Edouard Julien Again

Nick Wosika-USA TODAY Sports

Back in February, I wrote (and sang) about the electric debut of Edouard Julien, which featured excellent plate discipline and extreme platoon splits. The rookie second baseman ran a 136 wRC+ and put up 2.8 WAR in just 109 games, then hit even better in the postseason. Facing a steady diet of righties, Julien balanced out a precipitously high strikeout rate with an even better walk rate. He also balanced out roughly average raw power by hitting the ball hard consistently. This season, however, his strikeout rate has gone from high to untenable and his contact quality has taken a significant step back. Julien was sent down to Triple-A St. Paul to figure things out in June. Let’s take a look at what’s going on and how he might be able to fix it.

We should start by making it clear that Julien’s season, while disappointing, has not been disastrous by any means. He has a 93 wRC+, including a much improved 98 wRC+ against left-handed pitching (though once again it’s an extremely small sample size). He’s also improved his defense, and as a result, he’s put up 0.8 WAR over his 63 games with Minnesota. Prorated out over a full 162-game season, he’s right around league average at 2.1 WAR.

Rip-Roarin’ Reliever Roundup Rodeo 2024, Part II: The Wrangling

Sam Navarro-USA TODAY Sports

You didn’t really think teams were done swapping relievers after Friday and Saturday, did you? If you thought maybe they were tapped out for late relief help on Sunday and Monday, well, you thought wrong! If your bullpen doesn’t look like there are enough dudes to capture Helm’s Deep, you’re woefully short-armed.

The San Diego Padres acquired LHRP Tanner Scott and RHRP Bryan Hoeing from the Miami Marlins for LHSP Robby Snelling, RHSP Adam Mazur, 3B/2B Graham Pauley, and 3B/SS Jay Beshears

As one of baseball’s elite closers on an expiring contract, Tanner Scott was arguably the best short-term option available among relievers. His walk rate has peeked up a little to the numbers of the bad old days, but his first-strike percentage has stayed firmly in positive territory, which is an important indicator of where walk numbers will settle. Scott is likely to help the Padres in a very tight NL Wild Card race, but he’ll probably be even more important for them in the playoffs if they can get there. In San Diego, he teams up with Robert Suarez to asphyxiate opposing lineups late in the games. As far as elite closers who occasionally walk a few too many batters go, Scott is one of the less stressful of the genre, because he’s so hard to hit against with any authority, giving him a good shot at escaping jams following those free passes.

Bryan Hoeing is a sinker/slider reliever who has never quite clicked, as he’s never really been able to induce many swings-and-misses, nor has he mastered the art of inducing weak groundballs. He strikes me mostly as a depth guy who has plenty of years of club control left, and barring a breakout, he seems destined to be shuffled back and forth between San Diego and Triple-A El Paso a lot over the next few years. This trade is about Scott. Read the rest of this entry »


Pitching Prospect Update: Notes on Every Top 100 Arm

Sunday Notes: Cole Ragans Got His Tight Cluster Back By Moving on the Rubber

A more-consistent arm slot related to a move back to the third base side of the rubber has contributed to Cole Ragans’s success this season. The raw stuff was obviously already there. As Ben Clemens wrote back in March, the Kansas City Royals left-hander “looks like an absolute terror on the mound.” My colleague went on to say that if he “were designing a pitcher in a laboratory, he’d look a lot like Ragans.”

When I talked to the 2024 American League All-Star on the eve of the break, he told me that going into full attack mode following last year’s oft-reported velocity jump played a huge role in his emergence as a front-line starter. As he put it, “I kind of had to teach myself that I could get away with a little more of a miss compared to when I was throwing 90-91 [mph]. I have a good arsenal in my opinion, so I can just go after hitters.”

And then there’s the work he does in the laboratory.

“I use TrackMan in my bullpens, especially with the slider and the cutter, to kind of see where I’m at,” said Ragans, whose heater is now mid-to-high 90s. “The biggest thing for me is my release points, making sure that my pitches are in a tight cluster. I want everything coming out of the same tunnel. I don’t want to be throwing a fastball from this release height, and my slider from a lower release height.” Read the rest of this entry »


Five Things I Liked (Or Didn’t Like) This Week, July 19

Kevin Jairaj-USA TODAY Sports

Welcome to another edition of Five Things I Liked (Or Didn’t Like) this week. This is a strange week for the column. The All-Star break cut into the number of games available to watch; mathematically speaking, fewer games means fewer chances for weird things to happen. I took a weekend trip and didn’t watch any MLB games on Friday or Saturday. I’m also hard at work on the upcoming trade value series, which comes out between the All-Star game and the deadline every year – check back Monday for that annual exercise’s kickoff. In any case, that means this is a hodgepodge list: some stuff from this week, sure, but also plays and series that got left out last week, and some low-level baseball to boot. Thanks, as always, to ESPN’s Zach Lowe for the format idea. And two quick programming notes: I won’t be doing my regular Monday chat or Five Things next week; instead, I’ll be doing a jumbo-sized chat Friday morning.

1. The New Derby Format
The modern swing-happy Home Run Derby has been a great success, at least as far as I’m concerned. It’s more fun to see sluggers launch as many home runs as they possibly can than it is to see them agonize over every single swing. The format wasn’t perfect, though. I’m not trying to be a grump about it – is it even possible to be a grump about the Home Run Derby? – but there was one downside to the timed-round format: not enough drama.

The 2024 Replacement-Level Killers: Left Field & Right Field

Bill Streicher-USA TODAY Sports

Today the Killers list turns the corner — or rather turns to the teams receiving less-than-acceptable production in the outfield corners. While still focusing on teams that meet the loose definition of contenders (Playoff Odds of at least 9.5%), and that have gotten about 0.6 WAR or less out of a position thus far — which prorates to 1.0 WAR over a full season — I have also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance at that spot is worth a look.

As noted previously, some of these situations are more dire than others, particularly when taken in the context of the rest of their roster. I’ve batched the two corners together into one supersized roundup because three of the seven teams below the WAR cutoff for left field also make the list for right field, and because there’s plenty of crossover in play with regards to personnel. The capsules are listed in order of their left field rankings first, while noting those three crossover teams with an asterisk. As always, I don’t expect every team here to go out and track down upgrades before the July 30 deadline, but these are teams to keep an eye on. All statistics are through July 14.

I Saw a Bird

One of the fun things about baseball (that’s also one of the fun things about life in general) is that at any moment you can look for and find something that you alone are seeing, that you alone are paying enough attention to notice, that you alone care about. Last Wednesday, the Twins finally lost to the White Sox. The Twins had won their first eight matchups with the South Siders, and they would beat the Sox again later that day. In fact, if not for the opportunity to pummel the White Sox at frequent intervals, Minnesota’s first half would look much different and much darker. But just this once, in the first game of Wednesday’s doubleheader, the Twins lost to the White Sox.

The bird showed up sometime during the first inning. It wasn’t there when Carlos Correa slapped the 11th pitch of the game through the right side for a single, but in the bottom of the inning, when Andrew Vaughn grounded into a 5-4-3 double play and the camera whipped around the horn to follow the ball, there it was — perched on a steel cable right above the on-deck circle as if it had been there forever.

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.


Minnesota Twins Top 43 Prospects

Michael Cuneo/STARNEWS/USA TODAY NETWORK

Below is an analysis of the prospects in the farm system of the Minnesota Twins. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the fourth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

The Three Relievers With Four Fastballs

Stan Szeto-USA TODAY Sports; David Reginek-USA TODAY Sports; Brad Penner-USA TODAY Sports

Of all 193 relief pitchers with at least 20 innings pitched this season, exactly three have thrown four distinct types of fastballs a minimum of 20 times each: Reed Garrett, Chris Martin, and Cole Sands. They all have one non-fastball offering, but none of them throw it more than a quarter of the time. Justin Choi wrote recently about the strategic options available to pitchers with more than one fastball, but four? Four whole fastballs? These guys feel like doomsday preppers getting ready for some apocalyptic scenario where money is now worthless and fastballs are the new currency.

But anytime a new strategy pops up in baseball, it’s worth checking to see if the outliers are onto something others should attempt, or if their “one weird trick” to pitching works only for them. Shoot, maybe it doesn’t even work for them all that well. Regardless, we’re gonna get to the bottom of what’s going on with these pitchers and all the fastballs they’re hoarding.

Reed Garrett

Garrett has thrown 34.2 innings for the Mets so far this season, posting a 3.12 ERA and a 3.17 FIP. He’s struck out 37% of the batters he’s faced and walked 12%. His performance this year has earned him an ERA- of 81, firmly better than average. What the averages aren’t telling you is that Garrett started the season with a 0.57 ERA in March and April, a ridiculous run that earned him a full breakdown on his evolution from last season by Ben Clemens on April 23. But that April ERA had to buy new pants after swelling to 6.08 in May. His performance has regressed somewhat in June, settling somewhere between those extremes. The current version of Garrett is probably more representative of what the Mets should expect from him moving forward.

The table below shows a breakdown of Garrett’s pitch repertoire with the usage and a few metrics for evaluating each offering (run value per 100 pitches thrown, xwOBA, Stuff+, and Location+). The two most common fastball types (four-seamers, sinkers) that most pitchers feature at the center of their arsenals are the pitches he throws the least. But the metrics linked to Garrett’s outcomes — either actual outcomes (RV100) or expectations based on the characteristics of the outcomes (xwOBA) — agree with his decision to de-emphasizing those pitches. They like Garrett’s four-seamer the least, even though it has his highest velocity and second best Stuff+. The pitch’s Location+ score reveals its critical flaw: a lack of command. Stuff+, RV100, and xwOBA agree that his sweeper and splitter are his two best pitches. Based on usage, Garrett agrees with that assessment.

Reed Garrett Pitch Type Metrics
Pitch Type Usage RV100 wOBA xwOBA Stuff+ Location+
Cutter 24.3% -0.7 0.385 0.340 104 94
Splitter 23.9% 1.7 0.167 0.145 119 93
Sweeper 23.6% 1.5 0.183 0.187 133 106
Four-Seamer 18.7% -3.9 0.514 0.419 125 84
Sinker 9.5% -0.5 0.340 0.312 96 93

His pitches mostly hover around league average in terms of individual characteristics, but the sweeper and splitter are both a tick or two harder than average and generate a bit more spin leading to more horizontal break, which is likely why Stuff+ likes them more than the rest of Garrett’s arsenal.

Reed Garrett Pitch Characteristics
Pitch Type Velo Horizontal Break Vertical Break Spin Rate Spin Direction Horizontal Release Vertical Release Extension
Cutter 91.1 1.2 4.2 2446 11:00 -2.1 5.5 6.2
Sweeper 84.6 7.1 1.2 2750 9:00 -2.3 5.5 6.2
Splitter 87.4 -7.5 1.8 1544 2:45 -2.1 5.6 6.3
Four-Seamer 96.2 -5.5 9.9 2325 1:00 -1.9 5.7 6.2
Sinker 95.7 -10 6.1 2273 2:00 -2.2 5.6 6.2

He makes the most of middling pitches by playing them off one another. The sweeper and cutter mirror the spin direction of the sinker and the splitter. As a result the pitches look similar out of the hand but fork in four different directions as they approach the plate to keep the hitter guessing (see movement plot below). So even if hitters guess the horizontal direction correctly, they’ve still got two similarly spinning pitches that fan out vertically as they approach the plate.

Scatter plot depicting the horizontal and vertical break of Reed Garrett's pitches

Garrett deploys all of his pitches no matter the handedness of the hitter, but he does vary the flavor of his approach. To lefties, Garrett likes to fill the zone with his cutter and dangle the splitter down and away when looking for a chase. To righties, he keeps the hitter off balance by throwing the sweeper to a variety of locations, but then comes down and inside at varying speeds with the splitter and the sinker.

The flowchart below gives us an idea of Garrett’s sequencing habits. He tends to start hitters with a cutter or sweeper. Once ahead in the count, he’s more likely to play around on the periphery of the zone with his sweeper and splitter, whereas while behind in the count he rolls with the four-seamer and cutter as more zone-friendly options. The wOBA values for plate appearances passing through each given count indicate the approach works well in early counts and with two strikes, but not as well when the count forces him back into the zone, in part because his four-seam command limits his ability to actually hit the zone with that pitch when circumstances demand it.

Flowchart outlining Reed Garrett's pitch usage at each possible count

Here’s a representative example of how hitters respond to Garrett’s two-strike splitter.

Looking at swing metrics by pitch type, each pitch adds a valuable tool to his kit. The splitter is Garrett’s best combo play for inducing swings (56% swing rate) without courting disaster. The pitch owns his best swinging-strike rate (30%) and second lowest hard-hit rate (20%) when batters do connect. He gets batters to swing at 74% of the sinkers he throws in the zone, he uses the sweeper to induce weak contact (17% hard-hit rate), and turns to the cutter to mix things up. The four-seamer is the weak link in the chain so long as it keeps taking the scenic route to the catcher’s mitt.

Chris Martin

Martin has thrown 21.1 innings for the Red Sox in 2024, logging a 4.22 ERA with a 3.90 FIP. He’s struck out 28.2% of the batters he’s faced while walking just 2.4% of them. He has been on the IL since June 5 while proactively seeking help with anxiety.

Again, we’ll start with a synopsis of each pitch he throws according to the value metrics. Stuff+, RV100, and xwOBA all like his splitter best. The pitch is very similar to Garrett’s splitter from a velo/movement/spin perspective, but he doesn’t throw it nearly as much. His four-seamer is his next best pitch by RV100 and xwOBA, but fourth best by Stuff+. However, he locates it well enough to still get results. Martin’s cutter is his consensus third-best pitch, striking a balance between stuff and command to get the job done. Like Garrett, Martin’s non-fastball pitch is a sweeper, but unlike Garrett, he throws it so infrequently that it’s hardly worth discussing.

Chris Martin Pitch Type Metrics
Pitch Type Usage RV100 wOBA xwOBA Stuff+ Location+
Cutter 42.4% -0.7 0.329 0.290 106 111
Four-Seamer 31.8% 0.7 0.297 0.274 93 110
Splitter 15.6% 3.0 0.197 0.249 141 112
Sinker 8.4% -7.9 0.702 0.855 84 103
Sweeper 1.9% -9.2 0.592 0.521 103 136

His pitch characteristics all hover around average, thrown maybe a tick or two harder, but with slightly less spin and therefore less movement. What helps overcome somewhat middling profiles is a distinct release point created by his long levers. Though his delivery is composed of a pretty standard three-quarters-ish arm slot, the arm attached to his 6’8” frame allows him to release the ball several inches higher and farther to his right than other pitchers throwing from a similar slot.

Chris Martin Pitch Characteristics
Pitch Type Velo Horizontal Break Vertical Break Spin Rate Spin Direction Horizontal Release Vertical Release Extension
Cutter 92.2 -0.2 5.8 2191 11:45 -3.2 6.1 6.5
Four-Seamer 95.1 -6.6 9.4 2186 1:15 -2.9 6.2 6.5
Splitter 88.2 -7.0 1.7 1507 2:45 -3.1 6.1 6.6
Sinker 94.2 -9.6 6.2 2098 2:00 -3.1 6.0 6.6

Rather than mirroring the spin on his offerings like Garrett, Martin takes a different approach to cultivating deceit. The puzzle for his hitters is more akin to spotting the difference between two nearly identical photos. All of Martin’s pitches spin in a similar direction, and his four-seamer, sinker, and cutter do so at almost the same spin rates. Where they differ is in the amount of active spin, or the amount of spin contributing to the pitch’s movement. The four-seamer, as one might expect, has the most active spin and the most rise. The sinker has a little less active spin and creates more horizontal break and more drop. The cutter drops in a comparable fashion to the sinker, but refuses to follow his fellow fastballs and break toward the third base side. Then there’s the splitter that spins at a much slower rate and with less active spin, which translates to roughly the same amount of horizontal movement as his four-seamer, but with even more drop than the sinker. Yet another carbon copy, but with a small but crucial edit.

Scatter plot depicting the horizontal and vertical break of Chris Martin's pitches

Martin uses the same theory to guide his approach to both righties and lefties: Fill the zone with the primary fastball(s), use one of the secondary fastballs as a threat inside, and pepper the bottom of the zone with splitters. Against right-handers the four-seamer and cutter are the pitches he consistently throws to all parts of the zone and the sinker backs the hitter off the inner half of the plate. Against left-handers, Martin stays away from the sinker, so the cutter becomes the weapon he aims inside, while the four-seamer and the splitter maintain their existing roles.

The job of each fastball is further etched in stone by Martin’s sequencing, visualized below. He starts an overwhelming majority of hitters with the four-seamer or cutter and sticks to those zone-friendly pitches if he falls behind in the count. But if he gets ahead, Martin starts mixing in the splitter and sinker. His results tend to be better if he gets to those splitter/sinker counts, but it’s unclear whether that’s because of the effectiveness of those pitches or because he gets too predictable in unfavorable counts.

Flowchart outlining Chris Martin's pitch usage at each possible count

The swing metrics indicate Martin’s cutter is his best option for getting swings (55% swing rate) that lead to either strikes (13% swinging-strike rate) or weak contact (27% hard-hit rate). The splitter is his overall best bet for a swinging strike (19%), but when hitters do make contact, it yields the highest hard-hit rate (70%). The sinker is most effective when thrown in the zone because it has the lowest out-of-zone swing rate (18%) and in-zone contact rate (78%) compared to Martin’s other offerings. And avoiding contact is key, since the sinker has the second highest hard-hit rate (67%) of the bunch.

Cole Sands

Sands has pitched 32 innings for the Twins this season. Those innings have amounted to a 4.22 ERA and a 3.30 FIP. His strikeout rate sits at 28% and his walk rate is a measly 3%. Sands’ season trajectory mimics Garrett’s: on a rocket to the moon in April, a crash landing in May, and now back up and cruising at altitude in June. At his peak, Sands was striking out Shohei Ohtani on three pitches, and Minnesota was considering stretching him out to start while managing injuries in the rotation; now he’s settled into a multi-inning relief role.

Digging into Sands’ repertoire via the pitch evaluation metrics, his cutter, curveball, and splitter all clock in right around average according to Stuff+, but RV100 favors the four-seamer and hates the curve and split. Comparing the curveball’s xwOBA (.305) to its wOBA (.372) suggests the pitch’s actual outcomes have been a bit unlucky compared to what’s expected based on the batted ball characteristics, which in turn is likely deflating its RV100. Meanwhile the four-seamer and sinker both have better wOBAs when compared to their xwOBAs, suggesting some good luck has swung their way and their RV100s might be a little full of themselves. Luck doesn’t explain the metrics’ diverging opinions on the splitter, suggesting something is amiss with Sands’ execution. Hopefully, this contradiction will untangle itself as we proceed.

In terms of the movement profile broken down in the table below, Sands, like Garrett, mirrors the spin of his breaking ball relative to the four-seamer, sinker, and splitter in an attempt to disguise their true identities until it’s too late for the hitter to react. And concealing those identities is necessary because, as with the other two pitchers, Sands’ pitch characteristics are far more average than overpowering. The furthest he deviates from average is with his extension, but unfortunately he deviates in the wrong direction. His 5.8-foot extension puts Sands roughly six to eight inches below league average. Releasing the ball farther from home plate gives the hitter more of a chance to identify the pitch’s trajectory, which likely explains the lower Stuff+ scores relative to what Garrett and Martin receive for comparable pitches. And while we’re talking pitch trajectory, the extra couple inches of drop on his splitter relative to an average right-handed offering of the pitch might be too much of a good thing; at times it dives too far, too quickly to really tempt hitters.

How the pitches move relative to one another is basically a hybrid of what we’ve seen so far from Garrett and Martin. The fastballs land on the movement plot in roughly the same orientation as the other two, aside from being stretched more vertically. Sands’ curveball operates similarly to Garrett’s sweeper, just with more drop.

Like Martin, Sands doesn’t throw his sinker to lefties, but beyond that omission, Sands attacks hitters in the exact same manner regardless of handedness. He aims to fill up the zone with his four-seamer, works arm side with the cutter and sinker, and keeps the ball down and/or to the glove side with the splitter and curve.

Sands mostly sticks to the standard sequencing playbook, but he’ll reach for any of his non-splitter offerings to begin a plate appearance. If he gets ahead, expect a heavy mix of splitters and curveballs; if he falls behind, expect him to thrown mostly cutters and four-seamers. His adequate command keeps him competitive, since even after falling behind, the average outcomes remain respectable and in line with the more favorable counts.

Flowchart outlining Cole Sands' pitch usage at each possible count

The swing metrics suggest Sands’ cutter is his best option for inducing weak contact (51% swing rate, 32% hard-hit rate), the four-seamer has the lowest in-zone contact rate (80%) to pair with the second highest in-zone swing rate (71%), and the curveball is best for forcing swings out of the zone (35%) that lead to either a strike (14% swinging-strike rate) or weak contact (25% hard-hit rate).

***

With the four-fastball approach to relief pitching now fully dissected on the lab table before us, I can’t truly say we’ve discovered the next big thing that pitchers everywhere will be rushing to replicate. Though Garrett, Martin, and Sands are the only three relievers doing this out of almost 200, their approach is not as novel as those numbers suggest. What they’re actually doing is leaning on all of the classic pitching fundamentals: changing the hitter’s eye level, attacking the zone to get ahead in the count and then make the hitter chase, varying speeds, varying locations, keeping the hitter off balance. Most relievers execute these fundamentals using one or two overpowering pitches, or in lieu of dominant stuff, they cobble together a few crafty junk pitches. Garrett, Martin, and Sands pitch as if they were junkballers, but instead of throwing knuckleballs or Bugs Bunny changeups, they take their collection of middling fastballs and deploy them as junkballs. They mix and match movement profiles and velocities so hitters can’t sit on certain pitches or locations. They do all the same stuff every pitcher does; they just dress it up a little different. Which in and of itself is novel enough to still be impactful. After all, 10 Things I Hate About You is a singularly great movie, but it’s also a classic Shakespeare play, just dressed up a little differently.
