Let’s Examine Swing Path Diversity in the 2024 Playoffs

Jayne Kamin-Oncea-USA TODAY Sports

It’s the most wonderful time of the year: October baseball. As always in the playoffs, I’ve been keen to observe lineup construction and offensive personnel, particularly from a bat path perspective. Over the last few years especially, the matchup game has become more and more important as managers navigate the platoon advantage that comes from switching pitchers in and out of the game.

In 2023 and 2022, I explored how Vertical Bat Angle (VBA) can serve as a proxy for analyzing swing diversity in a team’s lineup. At first it started as a way of investigating why the Astros were so consistent in the playoffs, then it became a way for me to understand which lineups have the most versatility in bat path and handedness. In theory, the more versatility, the harder it is for a pitcher-catcher combination to game plan. If a lefty with a flat bat path hits ahead of a righty with a steep bat path — as is the case with Juan Soto and Aaron Judge — a pitcher is forced to execute two different approaches. If that variance carries through an entire lineup, good luck! Spoiler alert, I’m basically describing the Dodgers, but more on that later.

As I’ve said in countless blogs of mine, VBA is not a catch-all metric for describing bat path. Attack Angle (AA) and Vertical Entry Angle (VEA), among other metrics, are important for understanding the full story of each player’s path. But in this piece, I’m going to stick with just VBA because that’s what I’ve used for this piece in previous years. Here are a few key points that are important to rehash before showing the results.

For left-handed hitters, I made their average VBA negative to account for the fact that they swing from the other side of the plate. (VBA data is provided by SwingGraphs.) For switch-hitters, I multiplied their average VBA by -0.72 because the league-wide rate of switch-hitter plate appearances that come against righty pitchers — when they are batting lefty — is 72%. Additionally, even though I used regular-season VBA data, I included only hitters who’ve recorded at least one playoff plate appearance this year in the sample. By not including guys who didn’t bat during the postseason, the dataset is more representative of each playoff team’s VBA variance based on how its offense is currently constructed. With the remaining group of players, I took the variance of the VBAs on the given team and adjusted it to be a percentage above or below average. The average is set at 100, just like wRC+. Without further ado, here is the update on VBAVar+ for 2024:

2024 VBAVar+ Leaderboard
Team VBAVar+

DET 107.91
SDP 107.25
KCR 106.09

As I alluded to earlier, the Dodgers come out on top this year. Their addition of Shohei Ohtani is a big help. Shocker! He comes before Mookie Betts, who is then followed by Freddie Freeman. From a VBA perspective, these three hitters offer immediate variance atop the lineup. Ohtani’s VBA sits around 34 degrees on average (although we know he can alter his swing a ton). Betts offers a very similar VBA at just around 33.7 degrees, but his comes from the other side of the plate, and he is much shorter than Ohtani. After that, Freeman has one of the steepest swings in baseball at just over 40 degrees on average. The different angles are one way to illuminate how different they are as hitters. They force pitchers to execute multiple pitches in different locations because each of them has different strengths or weaknesses due to the shapes of their swings.

Being without a healthy Freeman takes a versatile layer out of the lineup. The first baseman is nursing a sprained ankle and bone bruise, an injury that would typically warrant a recovery time of four to six weeks. He did not play in the Dodgers’ 8-0 win over the Padres in Game 4 on Wednesday, but he is in the lineup for Friday night’s Game 5. Either way, he is not at full strength. During his Game 4 absence, Max Muncy moved over to his old home at first base, while Chris Taylor and Enrique Hernández split the third base duties. As the Dodgers showed in their Game 4 rout, they have plenty of other boppers following the three stars in their lineup. It starts with Teoscar Hernández’s neutral VBA of 33-34 degrees. He is followed by Muncy’s slightly flatter swing (31 degrees). Then comes the righty Will Smith with his steeper angle of about 36 degrees. The bottom third is highlighted by Gavin Lux and Tommy Edman, who provide pitchers another different look with their flatter swings (both less than 29 degrees on average). I know, I basically listed the entire lineup, but that’s exactly the point: The Dodgers have a ton of talented hitters with different swing profiles, making it very difficult for pitchers to come up with a concrete gameplan to get them out. Last season, the Dodgers were second in this metric. The additions of Ohtani, Teoscar Hernández, and Edman, as well as the return of Lux from injury, have helped push the Dodgers to the top of the list.

The Yankees also have plenty of star power in their lineup. They’ve struggled offensively thus far through their four playoff games and are just slightly above average in terms of lineup swing variance. Judge is their only hitter in this sample who has an average VBA above 33 degrees. However, as I mentioned earlier, the top of their lineup is all the more dangerous because their two best hitters, Judge and Soto, have completely different VBAs. Judge’s is 41 degrees, while Soto’s is 26, and they also come from different sides of the plate.

The Padres and Royals appear third and fourth on this leaderboard, respectively. San Diego’s placement is largely due to its ability to rotate left- and right-handed hitters. On Wednesday, the Padres’ lineup went like this: L, R, L, R, L, R, L, R, L. There is one spot that sticks out especially: Batting Manny Machado fourth and Jackson Merrill fifth. Machado’s flat swing is geared toward crushing heaters, while Merrill’s steeper swing (and versatility) allows him to hit sliders well. If pitchers want to spam sliders to Machado, they’re forced to adjust quickly and take a different approach with Merrill. Yes, that’s possible. But if it makes things even just slightly more difficult for pitchers, it’s worth it.

Kansas City is quite different from the other teams discussed so far because its offense is top heavy. Bobby Witt Jr. and Salvador Perez are the two key threats. If you’re not going to overwhelm pitchers offensively with a bunch of star power, at least give them varying looks, right? That’s what this lineup does. The Royals have a handful of lefty hitters with different VBAs, ranging from Kyle Isbel (very flat) to Adam Frazier (very steep). The Tigers, the other AL Central team to secure a Wild Card berth, are a similar story.

The Tigers have done just enough offensively during the playoffs so far. They haven’t really had a big breakout game, but their versatility has allowed A.J. Hinch to make pinch-hitting decisions that put his team in a better position to play against the strengths of Detroit’s opponents. A good example of this came in Game 2 of the Wild Card Series against the Houston Astros, when Andy Ibáñez pinch-hit for Zach McKinstry against left-hander Josh Hader in the eighth inning. From a handedness perspective, the move is straight forward; McKinstry bats left-handed while Ibáñez is a righty. But what makes this an especially shrewd move is the fact that, from a bat path perspective, Ibáñez might be an ideal matchup for the Tigers against Hader. Hader has a flat approach angle on his fastball, which he’s trying to keep above the bats of hitters, and Ibáñez has a flat swing — on average, his VBA hovered between 26 and 27 degrees this season — which helps him to avoid swinging beneath higher pitches. That’s exactly what happened. Hader fired a sinker up in the zone, and Ibáñez hammered it for a go-ahead double.

And sometimes, you have similar personnel who are all playing so well that having variance doesn’t matter all that much! That is exactly what’s happening in Queens. Almost the entire Mets lineup is within five degrees of VBA. The only exception is J.D. Martinez, who has a steeper path in the high 30s. I don’t think the Mets’ position all the way down on this leaderboard is a bad thing; good hitters are good hitters regardless of their swing paths. Putting together a lineup with a high VBA variance is just one way to build a winning team, but it’s far from the only way.

This is the third year I’ve done this exercise and it’s one of my personal favorites. The more context that can be added to a team’s lineup, the better you can understand matchups and managerial decisions. In the small sample of the playoffs, teams have to flex whatever competitive advantage is available. When you have the personnel to make life harder for your opponents, you better exercise it.


Tigers Take Game 3 Behind Strong Bullpen Performance

David Reginek-Imagn Images

If you’re into relief pitching and pinch-hitting, boy was Game 3 of the ALDS between the Cleveland Guardians and the Detroit Tigers the game for you. On the surface, it was fairly straightforward, a low-scoring affair that featured good pitching and a couple of timely hits. But look beneath the surface and you’ll see that it was quite a quirky game, one that would be difficult to explain to casuals (not derogatory!). Why was a healthy hitter pulled before he got an at-bat? Why did one of the biggest offensive threats on the Tigers get pulled in the fifth inning? Truly, it was a dream game if you love talking about the intricacies of baseball with your friends. And lucky for me, you’re all my friends today.

Let’s establish a few of the details before we dive into some of the nerdier aspects of Wednesday’s game. The Tigers won 3-0 to take a 2-1 series lead against their division rivals. Just as he had the last few months, A.J. Hinch put his faith in his bullpen, a unit that posted a 3.00 ERA (fourth in the game) in the second half as the Tigers put together the best record in the American League over that stretch. They delievered another superlative performance, and now his team has a chance to close out a playoff series at home Thursday night. Imagine telling Tigers fans that was possible in July!

There are 26 players on each of these flawed but fun AL Central rosters. Realistically, four of those 52 players (the starting pitchers from Games 1 and 2) weren’t going to appear in Game 3 unless it went a gazillion innings, leaving 48 who might see action. The Tigers used six pitchers and the Guardians used seven. Both teams used three pinch-hitters, while the Guardians also called on Austin Hedges as a defensive replacement (he ended up getting an at-bat), making for seven total substitutions between the two teams. Add those hurlers and pinch-hitters to each team’s starting lineup, and you end up with a whopping 38 players used! Not quite every player, but for a nine-inning game, that’s a lot! And all that mixing and matching added a fascinating dimension to the chess game, especially the pinch-hitting. Read the rest of this entry »


‘The J-Rod Show: Season 3’ Is Finally Catching Fire

Tim Heitman-Imagn Images

Julio Rodríguez’s season was growing bleaker and bleaker by the day as he labored through the longest slump of his short career. We had expected him to get right sooner than later — after all, he’s one of the most talented players in the sport, with an explosive bat, top-shelf sprint speed, and a cannon of an arm — but it was worrisome to see him struggle for so long. He had an 86 wRC+ across 360 plate appearances at the end of June.

Over the last few months, though, Rodríguez has progressively figured things out, with his turnaround culminating with his current heater. Since July 1, he is batting .321/.377/.545 with 12 home runs and a 166 wRC+, and over his last 10 games, fueled by his .458/.471/.833 line, five homers, and 270 wRC+, he’s added 1.3 WAR to his ledger. He is a key reason why the Mariners are still in the playoff race with less than a week remaining in the season, though you could also make the case that his overall underperformance is one of the reasons why Seattle is barely hanging around. Either way, to better understand the story of Rodríguez’s season, we have to dive deeper into his struggles.

Rodríguez pitch-by-pitch performance data show he spent the first three months of the season almost exclusively hunting fastballs, which isn’t a bad idea considering he feasts on them. The problem was that because his eyes were focused only on one speed, he started swinging at any pitch that he thought might be a fastball, and as a result, he was chasing too many breaking balls and offspeed pitches.

During the first three months of this season, Rodríguez may have been the worst everyday hitter against offspeed pitches in the entire sport. Among the 260 batters who saw at least 50 offspeed pitches outside the zone through the end of June, he had the second-worst chase rate at 54.9%, behind Nick Gordon. As a result, Rodríguez had a .157 wOBA against offspeed pitches, which dragged down his overall numbers, especially because he also had trouble against breaking balls (.232 wOBA).

Rodríguez’s feast-on-fastballs approach corresponded with a swing deviation that limited his production. In previous seasons, Rodríguez thrived because of his swing variability, which allowed him to do damage against different pitches in different locations. That is an essential skill for him because he is one of the more aggressive hitters in baseball. However, during the first months of this season, because he seemed to be selling out for fastballs, his hacks were too noisy on most of his swings. That type of one-dimensional swing is designed to crush higher-velocity meatballs — and, even as he struggled, he was still doing that — but it is susceptible to pretty much everything else.

When looking at SEAGER, it becomes clearer that Rodríguez truly did have an eat-the-meatball approach. Yet despite his increased chase rate against offspeed pitches, his SEAGER has actually improved from last year. His Selectivity% is about league average as of this week, in the 54th percentile (mainly due to recent improvements), but his Hittable Pitch Take% is in the 97th percentile, meaning he is rarely letting pitches he can damage pass him by. Altogether, he is in the 95th percentile for SEAGER, a jump from last year’s 69th percentile score. At first glance, this might seem contradictory, that he’s making better swing decisions during his worst season. But just because he is swinging at hittable pitches doesn’t mean those swings have enough variability to produce against pitches with different speeds and locations.

The thing is, even though Rodríguez was hunting heaters with a swing that is tailored to damage them, it doesn’t seem like he intentionally altered his mechanics. Rather, the two changes likely came about simultaneously and spiraled as they reinforced each other. Here’s what probably happened: After getting off to a slow start, he began pressing to break out of his funk and tried to clobber the most hittable pitches he saw, leading to a one-dimensional, fastball-dependent swing.

Rodríguez is at his best when he has a flatter Vertical Bat Angle (VBA). VBA is the angle of the barrel relative to the ground at contact. So that means his best performance has come when his bat has been flatter at contact. That could mean deeper contact and/or a flatter entry into the hitting zone. Flat swings don’t work for all hitters, but for a someone like Rodríguez who creates so much bat speed deep in the zone, they typically are a recipe for success. Over the first three months of the season, Rodríguez had the steepest VBA of his career, ranging between 33.4 to 35.5 degrees; this stretch coincided with his below-average offensive production. Since the beginning of July, though, he’s flattened his VBA to somewhere between 30 and 31 degrees, much more in line with his career norms.

Rodríguez’s upper body mechanics are crucial to his swing because they determine the path his bat takes to the ball. He has a louder bat row, similar to those of Vladimir Guerrero Jr. or Rafael Devers, two hitters who also have swings on the flatter side. Noisy movements help batters generate power and time up their swings, but with more movement comes more room for error when something goes awry. Having an effectively loud swing requires maintenance and attention to ensure the delicate balance between power and control doesn’t fall out of whack.

If Rodríguez’s swing had unintentionally become more vertically oriented because of a different setup or row, that could have disrupted where he perceived his bat to be in space (proprioception) and hindered his contact quality and frequency. This all makes sense in theory, but let’s confirm it with some video analysis. The first two swings below are from May and the next two are from July:

May

July

You can see a much more toned-down bat row in July compared to what it was in May. Since Rodríguez isn’t moving it as aggressively in the pre-swing, his bat starts on a flatter plane when he descends into his downswing. That helps decrease the amount of time it takes to get his barrel into the zone and is more in line with where his swing has been in the past.

Now, let’s compare two swings, one from last season when he was rolling, and another from the second half of this season, as he returned to form:

2023

His mechanics aren’t identical, but they are much closer now than they were when he was struggling during the first few months of this year. Pay attention to the angle of his bat throughout the row and how far his hands drift from his body. Maintaining the connection between his barrel/hands and the rest of his upper body is paramount for him to control his barrel.

As a last piece of information to consider, I was curious about how Rodríguez’s bat speed changed as his row calmed down a bit and his swing flattened back out. This month, his bat speed has ticked up significantly compared to the first three months of the season. He’s swinging at an average velocity of 77.7 mph in September, a sizable spike from April through June, when his average swing was just under 76.0 mph. If flatter means faster, then it sounds like he should stay where he’s at right now.

Any Mariners fan would tell you that in the first few months when Rodríguez was struggling, he was clearly pressing. Any player would tell you that when you start pressing, your swing can regress because of it. You try and hack your way back to your normal numbers and get too far from the best version of yourself. It’s an intuitive story.

Considering the Mariners were just eliminated from the AL West race Tuesday night and currently sit 2.5 games out of the final Wild Card spot with four games to play, it would have been nice for them to have gotten this version of Rodríguez a bit sooner. But the season isn’t over just yet. Maybe the young superstar can propel his team into an unlikely playoff berth. After “The J-Rod Show” got off to such a slow start this year, that would be an especially epic season finale.

Except for the standings, which include Tuesday’s results, all stats are updated as of Tuesday morning.


Jackson Merrill Is Already a Star

Denis Poroy-USA TODAY Sports

I will always have an affinity for hitters with a knack for vertical bat variability. To effectively cover pitches at different heights in the strike zone, a hitter has to vary the angle of their bat relative to the ground to create lift. To hit a pitch at the top of the zone for a line drive, the bat should be flatter, and to lift a pitch at the bottom of the zone for a line drive, the bat should be steeper. It’s a simple concept that some hitters can execute with more consistency than others. Jackson Merrill is one of those guys.

When I first really started getting into the mechanics of hitting, Mike Trout was the dude who made it easy to understand vertical bat variability. Vintage Trout’s lower half looked almost identical across all swings, but depending on the height of the pitch, his entire torso angle would adjust. Through the years, players like Michael Brantley, Freddie Freeman, and Trea Turner have all executed impressive levels of vertical bat variability, too. And unsurprisingly, they all maintained (or still do) strikeout rates well below the league average with great gap-to-gap line drive skills. When Eric Longenhagen first compared Merrill’s swing to that of Brantley, I became very impatient anticipating what the Padres outfielder would do in the big leagues. So far, he’s exceeded expectations.

Through his first 121 career games, Merrill has hit for a 125 wRC+ with a .290/.321/.484 slash line. Over the past month, he’s found his power stroke to go along with his superb line drive swing, and during that span, he’s been one of the best hitters in baseball, with a 182 wRC+ across 104 plate appearances. It’s come at a good time for the Padres, who have picked it up and are only three games behind the NL West-leading Dodgers.

Merrill’s sound mechanics and production at the plate are all the more impressive considering that he is still just a 21-year-old rookie who is also learning a new position. Although his outfield experience in the minors was limited to 45 innings in left field last year at Double-A, he’s already turned into one of the top defensive center fielders in the game (6 OAA).

His ability to go down and get it with the best of them while still covering the top of the strike zone is the key to his success so early in his career. Below is a table highlighting his performances in both the upper and lower thirds of the zone:

Merrill Performance by Vertical Zone
Zone xwOBA League Rank*
Upper Third .381 27
Middle Third .432 29
Lower Third .386 25
SOURCE: Baseball Savant
*Out of 194 batters to see at least 1,250 pitches as of Aug. 20

Elite hitters have all different shapes of production. Juan Soto mashes everything at the top of the zone, Aaron Judge crushes everything in the heart, and Yordan Alvarez demolishes everything down low. But it’s uncommon for hitters to be this productive on both high and low pitches. In fact, among the 194 hitters who’ve seen 1,250 pitches this season, only two other players have xwOBAs that rank in the top 30 on pitches in both the upper and lower thirds of the zone, Ketel Marte and Marcell Ozuna, who are two of the best 11 hitters in the game by wRC+. Merrill and Ozuna are the only two hitters with top-30 xwOBAs in all three vertical thirds.

As I said before, a hitter needs to employ a flatter swing path at the top of the zone and a steeper one at the bottom. Sounds easy enough, but the tricky part is generating enough bat speed across a range of bat angles to make it work from a damage perspective while maintaining the body control to make contact. What’s notable here is how Merrill does this: Unlike most hitters, Merrill keeps his bat vertically oriented against low and high pitches, which allows him create enough lift to shoot the gaps no matter the height of the pitch. It’s a balance of strength and finesse that Merrill seems to have mastered.

I could throw a bunch of numbers at you to explain this particular skill, but the best way to understand this is by watching what he does with his body and bat. Let’s take a look:

Upper Third

Before watching the lower third swings, here are a few quick notes. He maintains his posture and shoulder plane during all three of these swings. Because of that, he keeps his bat on the same vertical plane as these pitches so he can square up the bottom part of the baseball to create backspin but not get so far under it that he pops them up. Also, his torso backbend on the second swing is fantastic. This move is most noticeable from a hitter like Shohei Ohtani, who right before contact bends his upper body backward to give his barrel space to get behind the ball. Few hitters have the necessary upper body or t-spine flexibility to do this; Merrill is one of them. Okay, now onto some swings in the lower third:

Lower Third

Pay attention to his back shoulder on each of these swings. Merrill’s body and bat are moving together as he swings, and he uses his back shoulder as a guide to get his barrel on plane with pitches in the lower third. Whether it’s a back-foot breaking ball or a dotted heater away, his back shoulder angle lines up his swing.

The important thing to take away from all of this is Merrill has a great understanding of how to use his upper body to get his bat on plane with pitches at different heights. That’s the elite skill carrying his game right now. He has the talent to develop additional tools and sharpen the ones he currently owns as he gains more experience. He’s already started tapping into his power more over the last month or so. He still chases too many pitches and struggles against lefties, albeit in a small sample of plate appearances (70 wRC+, 127 PA), but again, he is 21 and figuring things out in his first big league season. What we’re seeing from him right now is essentially his starting point as a hitter, and that’s really exciting.


Ben Rice Has Built a Strong Foundation During His Limited Time

Vincent Carchietta-USA TODAY Sports

The smooth, lefty stroke has aged like fine wine through baseball history. Ben Rice is one of the latest examples of a left-handed hitter whose swing alone makes him fun to watch. Moving through the Yankees’ system as a bat-first catcher, Rice’s explosive minor league performance the last year forced his name into the big league conversation when first baseman Anthony Rizzo landed on the injured list with a fractured arm.

Even before Rizzo went down, Rice was mixing in more time at first base at Triple-A this season. That’s where the organizational need was, and his skills were not quite suited long-term at catcher anyway. As you’d expect, his defense at his new position has been a work in progress, and the same is true for the rest of his game. At the plate, Rice is experiencing the same ups and downs that most rookies do: Pitchers are figuring out how best to attack him, and he is learning how to make adjustments at the big league level.

With a 102 wRC+ over 142 plate appearances, Rice has been formidable thus far, but much of that is due to his hot streak that came along with his call-up. Across his first 19 games, he slashed .267/.348/.567 with five home runs, including the three against the Red Sox on July 6, and a 154 wRC+ over 69 plate appearances. During his 18 games (73 PA) since then, he’s batting .143/.247/.283 with two homers and a 53 wRC+. Despite that recent skid, ZiPS still believes in Rice, giving him a projected 110 wRC+ for the rest of the season. No projections come without uncertainty, of course, but there is a reason why ZiPS – and other projection systems – are confident the under-the-radar prospect can continue to be above average at the plate. Let’s get into it. Read the rest of this entry »


CJ Abrams Is Running Into Too Many Outs

Geoff Burke-USA TODAY Sports

CJ Abrams is one of the blossoming stars in today’s game. Entering play Friday, the 23-year-old shortstop who recently made his first All-Star appearance is batting .260/.333/.467 with 15 home runs, 16 stolen bases, a 122 wRC+, a .344 wOBA, and 1.9 WAR over 422 plate appearances. During the first month of what’s turned out to be his breakout season, I wrote about Abrams’ stellar offensive start. About a month-long slump followed, but he bounced back in late May and is showing that his plus-offensive profile is here to stay.

Now in his third season, Abrams is proving he can be the centerpiece that the Nationals can build around. Beyond his bat, his aggressive baserunning and speed make him one of the most dynamic young players in the game. Last year, despite his inconsistencies at the plate, Abrams was a menace on the paths. Thanks to his 28.6 ft/sec sprint speed (82nd percentile), according to Baseball Savant, he was worth +3 runs on the bases; he swiped 47 bags and had a 9.2 BsR.

This year, Abrams has been just as fast, but at least according to BsR, he is no longer a plus baserunner. (Baseball Savant says he’s been worth +1 run on the bases this year, which ranks 71st; he was no. 23 on last year’s leaderboard.) That’s because he’s been caught stealing 10 times already, with five of them coming via pickoffs, plus another pickoff that didn’t come on an attempted steal.

In 2023, Abrams went 47-for-51 on stolen base attempts. If he took off, the odds were in his favor. Pitchers weren’t exposing him for taking too big of leads or being overly aggressive. This year, his precipitous drop to 16-for-26 has been staggering. When a player who was so recently a great basestealer runs into a slump like this, it warrants a deep dive into understanding what exactly is going on. There are a few components of the steal that we have to pay attention to when trying diagnose this type of issue: the lead, the jump, and the situation. Let’s go through each piece and find out what’s gone wrong for Abrams. Here is a compilation of his pickoffs this year:

None of these look particularly great. He was either off balance or out by a good margin on almost every play. We can trace some of this back to his leads, so let’s start there. There are two main ways to take a lead against a lefty if you are thinking about attempting to steal second. You can take a normal 12-foot lead like Abrams did against Sean Manaea and then run on the pitcher’s first movement (as soon as the pitcher lifts his leg). Or, you can take a larger, one-way lead to possibly draw a throw over and get a feel for the pitcher’s pickoff move.

For the first one, you want to stay close enough to the bag so the pitcher doesn’t pick you off, but you want to get far enough out there that you have a good chance to be safe at second even if he does throw over; as soon as the pitcher lifts his leg, you break for second. For the one-way lead, you are an extra step or two toward second, but you are not attempting to steal on the upcoming pitch. Instead, you put all your weight on your left foot, toward first base, so you can dive back safely if the pitcher attempts to pick you off. If the pitcher doesn’t throw over, you are timing up his delivery so you can get a better jump if you decide to steal later. That doesn’t appear to be what Abrams was doing in the video above. All three times he has been picked off by a lefty this season have come early in the count, twice on the second pitch of the plate appearance and once on the first pitch.

In the 1-0 count against Manaea, Abrams took a standard 12-foot lead. He attempted to go on first movement but realized he would’ve been dead to rights, so he hesitated into shuffles instead. He should have just kept going and forced Pete Alonso to make a play. This was the most obvious mental mistake of the three. Against left-handers Kirby Snead and Alex Vesia, Abrams went on first movement, but because each pitcher expected him to go and was well-prepared to throw over, the defense caught him easily. As a pitcher, you know Abrams is an aggressive runner, but why in these two cases was it so easy? Well, this is a good time to point to Abrams’ tendencies.

Eight of his 16 swipes this season came on the first pitch, and of his six pickoffs, four were on the first pitch. If you’re a pitcher looking to control Abrams’ aggression, do it early. For lefties, it’s even easier to execute because you’re facing him as he leads off first. This goes back to the situational aspect I brought up before. Pitchers are smart, and these are the exact types of tidbits they become aware of as they prep for a good basestealer. Combine the early counts with pitchers being more willing to throw over if they haven’t yet used their allotted disengagements, and you have tough recipe for success. A potential solution here is for Abrams to wait for deeper counts before trying to steal.

The right-handed pitchers in these clips are equally prepared for Abrams to run early. He often uses the vault lead against righties. As a reminder, the vault lead is when you take your primary lead at about nine or 10 feet instead of 12. You take your same athletic stance and shuffle about 2-3 feet just as the pitcher lifts his leg. The momentum from your vault helps you accelerate into your sprint quicker than you would with a traditional, static lead, albeit with risks. The key to a successful vault lead is not the size of your shuffle; it’s your timing. If you venture too far out before or after the shuffle, or you mistime your vault and are in the air when the pitcher disengages to throw over, you risk getting picked off.

At times this season, Abrams has made both mistakes on his vault leads: Either his primary leads or his shuffles are too large. The vault lead is more technical than physical, based more on mechanics than reflexes and pure speed. Abrams is fast enough and reacts quick enough to steal bases with a traditional lead against favorable matchups, so if I were him, I would temporarily abandon the vault lead and work on getting the fundamentals down again before bringing it back in games.

Before letting you go, I also want to look at the plays on which Abrams was thrown out by a catcher to see if these caught stealings were because of bad decisions, poor jumps, or good defense. Here is a quick reel:

Off the rip, there are three plays that stick out. If you’re going to attempt steals against Gabriel Moreno and Patrick Bailey – perhaps the two best throwers in the sport – you have to pick your spots wisely. In the Arizona game, the Nationals were up two runs and the count was 0-2, providing a good opportunity to run and try to avoid a double play; against the Giants, my guess is he wanted to get into scoring position with two outs. These are valid enough reasons to run despite the poor matchups and are not comparable to the pickoff mistakes.

In the game against the Red Sox, righty Brayan Bello, who has an extremely quick slide step, was on the bump. Even runners who are faster than Abrams would have trouble reaching second safely when a pitcher delivers a 96-mph heater in the middle of the zone on a slide step. And perhaps not surprisingly, this came on the first pitch of the at-bat.

On the first play in the clip, against the Rockies, Abrams attempted to swipe third with a left-handed batter up. Even without seeing the quality of the lead that Abrams took, this was a bad decision. Dakota Hudson never took his eye off of Abrams before he delivered his pitch, making it much more difficult for him to get a good jump. On top of that, catchers love when this happens because with a lefty batting they have a clear throwing lane to third base; when righties are hitting, catchers have a more difficult play because they need to step back and around the batter before firing. Even with an inaccurate throw from catcher Jacob Stallings, Abrams was canned.

Abrams is an aggressive runner. Without his aggressions, he wouldn’t be able to steal nearly 50 bases in a season like he did last year. This isn’t something you want to take away from him. However, he does need to learn from these mistakes so he can use his speed and aggression more effectively. Most of these pickoffs and unsuccessful steals resulted from some a combination of being predictable and getting too jumpy. The good news is he is talented enough to make the necessary adjustments. Once that happens, we’ll get to see a much more complete version of Abrams, one who can swipe 40 bags at a high clip and pepper the gaps with line drives.


Baserunning Is All About Taking Calculated Risks

Peter Aiken-USA TODAY Sports

Like most things in baseball, baserunning is a blend of skills and smarts. It helps to be one of the faster guys in the league, but there are players who provide above average value on the bases despite not having above average speed, as instincts and feel can often make the difference between being safe or out.

One of my favorite parts of baserunning is the judgement calls that players are forced to make while running at full speed and expelling all their power and athleticism. In those moments, they have split seconds to weigh the many factors that can impact their chances of getting the extra base. While basestealing may be the single most exciting part of the game, the decision of whether to try and swipe a bag is much more black and white than other base-running plays.

Say you’re a major leaguer leading off first base and are determining whether to attempt to steal second. You already know the catcher’s pop time, and you have a pretty good idea of how long it takes the pitcher to deliver his pitch. You’re also familiar with the pitcher’s pickoff tendencies and footwork, as well as your own speed and ability to time your jump. Yes, maybe you can pick up on a pattern in real time that gives you a slight competitive advantage, or you notice either the pitcher, catcher, or both of them aren’t paying you much attention, allowing you to catch them by surprise. But for the most part, your decision to take off for second is still almost entirely going to come down to how fast all parties involved can boogie.

On the contrary, if you’re at the plate and lace a liner in the gap that splits two outfielders, you’re faced with several different variables that affect your decision outside of just your speed. How quickly do you get out of the box? Are you thinking two right away, meaning you’re running hard and already taking the angle that will allow you to cut the corner of first base and make a good turn that will give you a direct line to second.

From there, it’s based on feel and whatever data points you have in your head about the outfielders going for the ball. Which one is going to get there first? Does he have a strong arm? If so, is he accurate? Are his throws any weaker and less accurate if he’s pacing on a diagonal toward the gap and has to plant and throw off his back foot? Or, is the outfielder going to get to the ball quickly and have time to circle it, set his feet, crow-hop, and fire? There are other factors on top of these, too.

Let’s check out a few examples from some of the best base-running plays of the year. I’ll be using Statcast’s Runner Runs metric as a guide for choosing plays. This metric estimates the success rate for each base-running opportunity based on variables such as runner speed, outfielder arm strength, and distance from the given bag. Below, I’ve selected three plays — one at second, one at third, and one at home — that were worth at least .20 runs added.

We begin with a hustle double from Bobby Witt Jr.:

Sheesh! Out of the box, this looked like a clear single, even when you consider Witt’s 100th percentile sprint speed. This is a typical line drive to center field, not one that splits two defenders. But Witt knew that in this situation — runners on second and third with one out in the seventh inning and the Royals leading 4-2 — the Tigers might throw to the plate instead of second; he also knew who was playing center field.

Riley Greene, an above average left fielder, had shifted shifted over to center earlier in the game, and his skills don’t exactly fit as well there. He has 66th percentile speed and 48th percentile arm strength. On top of that, Greene throws left-handed, meaning that because he was roaming to his right side (toward the left-center gap), he’d either have to take a few steps to line his body up with second (as he did) or plant his feet in the ground and pirouette before getting rid of the ball. In other words, this play is easier for a right-handed thrower. Add up all those factors, and you have a perfect recipe for Witt to take a calculated risk with only one out. If Matt Vierling were still playing center, as he was at the beginning of the game, his speed and righty throwing might have kept Witt at bay. Every single one of these details matters!

The next play features Anthony Volpe pushing for a triple on a line drive down the right field line. Volpe has very good, but not elite, speed (28.6 ft/sec, 86th percentile), and because of that he’s a bit more reliant on his decision-making than Witt. On this play, he had a favorable spray angle, but it was going to be bang-bang as long as Jo Adell played it right:

To me, Volpe seemed to realize that he had a shot at a triple as he rounded first and saw the ball bouncing around off the curved fence in right field. He didn’t have a particularly great turn around the bag, but the slight ricochet gave him enough leeway. Typically, runners should look up at the third base coach once they’re getting to second base, but in this case, Volpe was going three no matter what and kept his head down.

Adell delivered a great throw to the cutoff man, but the relay to third was short-hopped, which made it more difficult for the third baseman to field it cleanly and apply the tag before Volpe slid in safely. This is an example of a challenge play, where Volpe put the pressure on the fielders to do everything correctly, and because there were multiple steps that had to be executed perfectly, Volpe liked his odds that one part of the chain would be off by just enough for him to make it.

Coincidentally, our final play comes from the same Royals-Tigers series that also featured the Witt double from above. And like that play, the outfielder was Riley Greene. Though this time, the runner was MJ Melendez, who despite his 68th percentile speed has done well on the basepaths this year, with +2 Runner Runs. The play we’re about to watch shows how a runner with just slightly above-average speed can put himself in a position to have above-average outcomes. Here it is:

Wait a sec, how did he get around to score on a fly ball that seemed likely to be caught? You can’t see it on the broadcast, but Melendez played this exactly right. On a towering fly ball like this one, a runner who begins the play at first should be waiting on second base, ready to pivot in either direction. Once Greene dropped the ball, it was time to take off, and even though the ball landed right at Greene’s feet, there was enough time for Melendez to make it home ahead of the throw. That’s despite the fact that Melendez stumbled on his way around third base; he made up for that because he was in the right place when the ball dropped. Also, remember that Greene doesn’t have a particularly strong arm and was all the way out at the warning track.

We could keep going, but by looking at plays at second, third, and home, we now have a better idea of the circumstances that affect base-running decisions. We saw how electrifying speed can manifest plays out of nowhere, but also how sound fundamentals can put runners in a strong position for success. As you’re watching ball for the rest of the summer, pay attention to these types of plays and see if you can pick up on the factors that baserunners must consider when weighing whether to take the extra base. These small details can have a major impact.


Can Royce Lewis Sustain His Elite Contact Quality?

Jesse Johnson-USA TODAY Sports

Royce Lewis is one of the most intriguing hitters in the game right now. Despite how fantastic he has been on a rate basis, it’s hard to fully evaluate his overall value as a hitter because of how little he has played. He has amassed 4.1 WAR and a 159 wRC+ across 93 career games, but as is well known, he’s been limited due to a series of injuries that includes two ACL tears, quadricep and hamstring issues, and an oblique strain.

This season, his explosive performance has added some confidence in what he can be as a hitter. Despite suffering a quad injury on Opening Day that kept him out of the lineup for two months, he’s clobbered 10 home runs in 23 games, showing that he doesn’t need a bunch of plate appearances to shake the rust off his swing before catching fire. His raw talent has never been in question, but there’s one part of his game throughout his power surge that seems to defy logic and is worth keeping an eye on moving forward: His xwOBACON sat at .473 entering play Sunday. If he were a qualified hitter, that would rank in the top decile. Given what we’ve seen from Lewis, that isn’t all too shocking – he can really put a charge into the ball. But when zooming in a bit on a particular detail of his swing, it becomes a bit surprising. Here are the leaders in xwOBACON to date in 2024:

2024 xwOBACON Leaders
Player xwOBACON VBA
Aaron Judge .627 39.4
Shohei Ohtani .556 32.3
Brent Rooker .541 34.5
Marcell Ozuna .530 34.4
Giancarlo Stanton .508 27.4
Juan Soto .507 26.1
Rafael Devers .485 27.5
Gunnar Henderson .478 30.6
Royce Lewis .473 27.3
Fernando Tatis Jr. .474 31.5
Colton Cowser .471 37.5
Oneil Cruz .471 32.2
Bobby Witt Jr. .468 28.8
Ryan McMahon .463 37.4
Nolan Gorman .462 37.1
All players except for Lewis are qualified hitters.

I’ve included Vertical Bat Angle (VBA) here because, except for Juan Soto, Lewis has the lowest average VBA of all hitters on this list. After Lewis, the hitter with the next-lowest VBA is Giancarlo Stanton, who generates so much power and bat speed that it would be nearly impossible for him not to have a top-of-the-line xwOBACON, even with such an unorthodox swing. How Soto can impact the baseball with ferocity despite having one of the flattest swings in the entire game is a bit more complex. The simplest explanation is he has incredible upper body athleticism, which allows him to let the ball get extremely deep in the hitting zone and still adjust his bat path to get on plane with the pitch.

Otherwise, though, hitters hardly ever generate this level of contact quality with these types of VBAs. So it’s remarkable that Lewis is among the exceptions. For the rest of this piece, let’s ignore Stanton because he is, in the words of Yankees manager Aaron Boone, a “weirdo” and what he does with his violent, choppy swing is almost certainly impossible to replicate. Soto is also a singular hitter; the difference is that what he does — using his flatter bat path to make more consistent contact while still having the strength to do damage, and pairing that hit tool with 80-grade swing decisions — would be worth emulating if anyone were talented enough to do it. At a glance, it seems Lewis might have the skills to follow a somewhat similar recipe. So far this season, Lewis has a 98th percentile SEAGER, a metric from Robert Orr that weighs how selective hitter are and the rate at which they attack hittable pitches. It’s especially encouraging that Lewis lets only 28.2% of hittable pitches pass him by, meaning that when he gets a pitch he can crush, he’s attacks it. That’s a great foundation to have.

To better understand his swing, I’ll refer you all to the third hitting installment from Tess Taruskin’s invaluable video scouting series, specifically the part where she compares grooved and adjustable swings. Because Lewis is a hitter with such a flat swing, my initial hunch was that most of his damage comes against pitches down the middle or in top half of the zone, leaving a hole for pitchers to target at the bottom of the zone. This would indicate that Lewis would have a grooved swing, one that repeats a specific swing path over and over, leading to a limited space for barrels. Although Lewis’ sample size is still hardly significant this year, it’s worth looking at where his best swings in terms of contact quality have been located. Here are his 10 home runs this season:

Interesting. All of Lewis’ homers have come from the middle of the zone. That’s not necessarily a bad thing – the best hitters in baseball are the ones who crush mistakes the most often. And as we saw from his SEAGER, he is great at attacking pitches in hittable zones. Basically, we can’t just knock him simply because his homers come from meatballs. However, it’s relevant context to the conversation around distinguishing whether his swing is grooved or adjustable. To go a bit further than just his pitch chart on home runs, we can look at his performance by zone to see if he’s had a hole below the zone.

Lewis has actually been quite successful in the bottom of third of the zone, with a .380 wOBA and .355 xwOBA on pitches in this location. (I included both 2023 and 2024 to increase the sample size a bit.) That’s pretty impressive for a hitter with such a flat swing. Soto’s wOBA/xwOBA line in that span is .264/.260, though his sample is much larger. Lewis’ contact quality on lower-third pitches is also quite strong.

Looking at video, it becomes clear how Lewis is succeeding against lower-third pitches, and this is where he is different from Soto. Remember, it is Soto’s upper body flexibility that propels him to impact pitches that get deep in the zone against him. Lewis, on the other hand, uses his lower body to get down in the zone and do damage on pitches in the bottom third:

If you focus on where Lewis’ head starts on these swings versus where it finishes, you can see the angles he can create with his lower body to get his barrel to the lower third despite his flat swing. It’s reminiscent of Fernando Tatis Jr. The hands start high and stay high, but the lower body creates space for the barrel to still maintain a positive attack angle – the angle of the bat path at contact relative to the ground – at the bottom of the zone. It’s a difficult move to make, but when your swing is this adjustable, you can rely on it from time to time when you identify pitches correctly.

The contrast between Lewis and Soto is a great reminder of how different hitters can be, even when a key trait in their swings is similar. Lewis’ superpower lies in his lower body. Whether the pitch is inside, outside, or in the middle of the zone, he uses his legs and hips to go down and get pitches.

Now, if I were an opposing pitcher, I’d challenge Lewis to make these moves over and over again and prove he can still elevate pitches down in the zone. Like I’ve said, we’re dealing with a limited sample. However, based on what we’ve seen so far, there is reason to believe Lewis has the skills needed to continue producing elite contact with his flat swing.


Zach Neto Is Proving To Be a Bright Spot in Anaheim

Jayne Kamin-Oncea-USA TODAY Sports

Things aren’t particularly bright in Anaheim right now, but even amidst the Angels’ struggles, some of the team’s young players are thriving. One of those players is Zach Neto, who in his sophomore campaign looks like an improved version of himself at the plate. His full-season wRC+ is up to 107, a mark that has been propelled by continued improvement as temperatures have gotten warmer. In the first month of the season, Neto posted a meager 79 wRC+, but in the two that have followed, he has looked like an All-Star, with a 130 wRC+ in May and a 123 so far in June. Despite not having big raw power, he’s been able to consistently drive the ball.

Last year, Neto was abysmal in the top third of the strike zone. He simply couldn’t handle high heaters, with his .194 wOBA in that area of the zone in the bottom decile of the league. It’s a hole that is too easy to expose. Any pitcher with a decent four-seamer that features at least average ride could live there when facing Neto and not be worried the shortstop would do any damage. It was a problem that held back his entire offensive profile, and without mitigating it, his prospects as a hitter weren’t promising. But as struggling young players often do, Neto looked to make a change. Read the rest of this entry »


Let’s Look at the Data Behind Bo Bichette’s No-Stride Approach

Kamil Krzaczynski-USA TODAY Sports

Bo Bichette is a ton of fun to watch at the plate, and that’s especially the case in two-strike counts. He takes on the old school approach of physically altering his swing to avoid striking out. There is something aesthetically pleasing about a player who refuses to strike out; it’s admirable, even. It can also be rewarding.

Bichette has used a no-stride two-strike approach his entire career, but back in 2022, he started standing a bit taller, with his weight pre-shifted into his rear hip to go along with his no-stride load. In 2021, his .212 wOBA with two strikes was well behind the league-wide mark of .236. As a hitter with an above-average hit tool and a knack for making good contact on pitches off the plate, that performance simply wasn’t good enough. Indeed, it’s the exact sort of thing that would force most hitters to try something else, which is what Bichette did. While his wOBA and xwOBA in two-strike counts showed no tangible improvement, 2022 was (and still is) his best full season by wRC+ (130). Whatever the results were, Bichette’s overall offensive game was thriving, so instead of reverting back to the more crouched setup, he built upon his new two-strike stance to improve it.

In 2023, Bichette’s .233 two-strike wOBA was in line with the league average (.232), while his .250 xwOBA was .018 points higher than league average. He decreased his whiff rate with two strikes by about four percentage points from 2022, and his strikeout rate dropped three percentage points as a result. That’s notable, of course, but remember: More contact isn’t always better for a chase-prone player like Bichette, as a batter’s quality of contact on pitches outside the zone is typically worse than on those over the plate. The key here is that Bichette’s reduction in whiffs came with better contact; last year he had the best xwOBACON with two strikes (.389) of his career. Read the rest of this entry »
