The Diamondbacks won a wild game against the Brewers at Chase Field on Sunday, one in which they built and then squandered a 5-0 lead, overcame an 8-5 deficit to send the game to extra innings, fell behind 10-8 in the 10th inning, and finally, won in walk-off fashion, 11-10. Eugenio Suárez was at the center of much of the excitement. The 33-year-old third baseman drove in the game’s first run, and later plated both the tying and winning runs as well. It was the latest stellar performance of the player who’s been the NL’s hottest hitter since the beginning of July, digging his way out of an early-season slump.

Suárez began his Sunday afternoon by slapping a one-out RBI single off DL Hall through the right side of the infield, bringing home the first of three runs that the Diamondbacks scored in that frame. Facing Hall again, he struck out in the third before Arizona mounted a two-out, two-run rally that extended its lead to 5-0. Suárez grounded out against Joe Ross to end the fourth, and struck out again, against Aaron Ashby, to end the sixth, by which point the Brewers had pulled ahead 7-5 after chasing Zac Gallen and roughing up reliever Kevin Ginkel.

After the Diamondbacks scored two runs to cut the lead to 8-7 in the seventh, Suárez hit a sacrifice fly that brought home Corbin Carroll — who had walked, stolen second, and taken third on a wild pitch — in the eighth. Milwaukee scored two in the top of the 10th, but in the bottom of the frame, four straight Diamondbacks reached base, via three singles and a hit-by-pitch, before Suárez swatted a towering 100.5-mph fly ball that bounced off the right-center field wall, driving home Ketel Marte with the winning run.

Colton Cowser is a leading contender for American League Rookie of the Year honors, and his power numbers are among the reasons why. The 24-year-old Baltimore Orioles outfielder has 20 home runs to go with a .240/.321/.431 slash line and a 115 wRC+. San Diego’s Jackson Merrill (23) is the only rookie in either league to have left the yard more times.

That Cowser is clearing fences with some regularity is in many ways unsurprising. At a listed 6-foot-2, 220 pounds, his build is that of a basher. That said, his profile going forward wasn’t entirely clear when he was first featured here at FanGraphs in February 2022. Drafted fifth overall the previous summer out of Sam Houston State University, Cowser had propelled just a pair of baseballs over outfield barriers in 149 low-level plate appearances. Moreover, as I related to him in our offseason conversation, Baseball America had recently cited his “impressive walk-to-strikeout ratio,” adding that his swing path is “presently more geared toward contact versus power.”

The numbers suggest that Cowser is no longer the same style of hitter. After having more free passes than Ks in college and in his first taste of professional action, the left-handed-swinging slugger has fanned a team-worst 157 times this season with a 30.5% strikeout rate and a 9.5% walk rate. He’s also hitting more balls in the air, as evidenced by his 38.2 FB%. That number was just 26.9 in his two-plus years down on the farm.

Cowser’s thoughts on making less contact as he settles in to what promises to be a productive MLB career? Read the rest of this entry »

Even in an age in which baseball – and most sports to an extent – has become an extremely data-driven enterprise, the stew of conventional wisdom, mythology, and storylines could still feed a pretty large family. That’s not to say that this is a bad thing; even an old, jaded stat nerd like me gets excited to enjoy such a stew from time to time. But at the end of the day, an analyst has to focus on what’s true and what is not, and very few bits of baseball orthodoxy are more persistent than that of the sophomore slump. Coined for underperforming second-year high school or college athletes, the meaning in baseball is roughly parallel it: After a successful rookie season, a player finds it difficult to maintain the performance from their debut and are weighed down by the greatly increased expectations. As an analyst, the inevitable follow-up question is whether the sophomore slump is actually real.

While I entered this article with some rather developed skepticism, there’s no denying that high-performing rookies do occasionally have pretty wretched follow-up campaigns. Every longtime baseball fan can probably rattle off a dozen or so names instantly after reading the title of the article. For me, visions of Joe Charboneau, Pat Listach, Mark Fidrych, Jerome Walton, and Chris Coghlan dance in my head. And the list goes on and on. However, a second-year skid doesn’t mean there’s a special effect that causes it. The fact of the matter is that you should expect a lot of regression toward the mean for any player in baseball who can be optioned freely to the minors. The way baseball’s minor league system works accentuates the selection bias; underperforming rookies are typically demoted while the ones crushing reasonable expectations get to stay.

Looking at the sophomore slumpers, the story is typically more complicated than the cautionary tale. ZiPS has minor league translations going back to 1950 at this point, and while Super Joe (Charboneau) hit very well in the season before his debut (.352/.422/.597 for Double-A Chattanooga), at 24, he wasn’t young for the level, and ZiPS takes enough air out of that line to drop his translated OPS below .800. ZiPS thought he’d be an OK lefty-masher, but not much more than that.

Charboneau had a solid offensive rookie season, winning the AL Rookie of the Year award, but in his case, the fates didn’t really give him a fair opportunity to repeat that season. He injured his back in spring training and played through the injury, as was the style of the time. Across a couple of stints in the majors after his rookie breakout, he combined to bat .210/.247/.362 over 147 at-bats, and he was never healthy or trusted enough to make good. He didn’t hit again in the minors, either, with the only exception a walk-heavy .791 OPS as a 29-year-old in A-Ball (!).

As quick as Charboneau’s fall from grace was, it was far from the biggest rookie WAR drop-off. Using the definition of rookie in our leaderboards, which doesn’t know about roster service time days but is suitable for the approach of identifying rookies rather than specific Rookie of the Year eligibility, here are the biggest sophomore slides by WAR since 1901.

Some of these players recovered to have solid major league careers and some of these slumps resulted from serious injury, such as Kerry Wood’s, but for some of the players, that was the end of the road for them in the big leagues. As for Super Joe, his skid was the 100th worst in history among hitters!

So, how do we extract a sophomore-slump effect from simple sophomore slumps? At this point, I’ve been running projections for two decades, so I have a decent-sized database of projections calculated contemporaneously (as opposed to backfilling before ZiPS existed). I certainly haven’t told ZiPS to give a special penalty to solid rookies having bad follow-up campaigns, so I went back and looked at the projections vs. realities for every hitter with a two-WAR rookie season and every pitcher who eclipsed 1.5 WAR. (Rookie pitchers tend to have more trouble grabbing playing time.) That gave me 166 hitters and 207 pitchers. Let’s start with the hitters.

The 26 players in the top bucket averaged 5.1 WAR in their rookie seasons and 3.7 WAR in their sophomore seasons. That’s a pretty significant drop-off, but they were projected for an even steeper decline. The next group — 44 players who accumulated 3-4 WAR as rookies — underperformed its projection by about two runs per player, while the 96 rookies who finished with 2-3 WAR slightly overperformed their projections, but it was very close. As for the entire sample of 166 hitters, ZiPS projected a decline from an average 3.1 WAR as rookies to 2.3 in their sophomore seasons. Their actual average in their second year was… 2.3 WAR. Let’s look at the pitchers.

This is the same story, with the decline for pitchers being about as predictable as it was for hitters: ZiPS underestimated their second-year WAR by about 0.08 wins on average.

That’s not the end of it, however. I wanted to see if ZiPS has projected a similar decline for players who were coming off their second through fifth seasons, because that would determine whether ZiPS was capturing a sophomore-slump effect or if this was just a more general regression to the mean for players with less major league experience.

In sum, ZiPS didn’t knock more performance off high-performing rookies than it did for sophomores, juniors, seniors, and guys who stayed a fifth year because they had to drop too many 8 a.m. classes that they slept through. That’s because the sophomore-slump effect doesn’t exist.

So yes, projections will likely project fewer WAR next season from this year’s standout rookies, such as Jackson Merrill, Jackson Chourio, and Masyn Winn. But that dip is likely to be the result of the typical regression toward the mean that any high performer with a limited track record is expected to experience.

If I’ve learned anything from the new Statcast bat tracking data, it’s that bat speed alone isn’t sufficient to produce a high-quality major league hitter. Johnathan Rodriguez, Trey Cabbage, Zach Dezenzo, Jerar Encarnacion — all of these guys, at this early stage of their major league careers, swing hard but miss harder. Bat speed only matters when you make contact.

When you do hit the ball, however, it’s nice when your swing is as fast as possible. Swinging fast while making good contact most of the time — it’s hard to do, but if you can do it, you’re probably one of the best hitters in baseball.

The reason it’s rare is because these two variables — swinging hard and making solid contact — are negatively correlated. As some probably remember from when these stats originally dropped, Luis Arraez swings the slowest and squares up everything, while Giancarlo Stanton swings the fastest but seldom connects. A slow swing is a more precise swing, and so the group of hitters who can swing precisely while letting it rip are uncommon.

In order to determine who these rare hitters are, it is necessary to select some arbitrary cutoffs. I’ve picked hitters who have roughly 80th percentile bat speeds and 50th percentile squared-up per swing rates. (A “squared-up” swing is one where a hitter maximizes their exit velocity.) Here is the whole list of hitters who average over 74 mph of bat speed and have at least a league-average squared-up rate: Yordan Alvarez, Gunnar Henderson, Manny Machado, William Contreras, Juan Soto, Vladimir Guerrero Jr., and… Lawrence Butler???

A ballplayer who grabs a bat and steps up to the plate aims to hit. The point of the sport is to go around the bases, and the most efficient way to do that is to put wood on the ball and hope for the best. But it’s far from the only way to go around the bases.

Sometimes you hit the ball, and sometimes the ball hits you. I’ve long been fascinated by players who use their own bodies as a means of advancement, dating back to when I, as a child, read a George Vecsey feature on the single-season hit-by-pitch leader in an old anthology of baseball writing. “Ron Hunt, Loner,” painted a broadly ambivalent portrait of a second baseman with modest physical gifts. But Hunt made two All-Star teams and retired with the same career OBP as Shohei Ohtani, despite playing in the most pitcher-friendly era of the past 100 years.

Those who are able to systematize the hit-by pitch can transform their careers. Read the rest of this entry »

Welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. September is a magical time for baseball. Half of the games are mostly for fun, with teams playing out the string and competing for bragging rights. Those games produce some delightful nonsense, because teams are often more willing to engage in tomfoolery when the stakes are low. The other half of the games (using half very broadly here, of course) are far more important than any games from earlier in the season; they determine playoff berths, home field advantage, and statistical milestones. Those games have all the intensity missing from the other half, right down to electric crowds and locked-in benches. That duality is a ton of fun. This year, we’ve even got a truly historic statistical chase going on to add to the excitement. Zach Lowe’s NBA column, which inspired this series, always hits its stride when teams are building up for the playoffs. I think that baseball trends in the same direction. Let’s get right to it.

1. When the Ball Doesn’t Lie

This is just outrageous:

The umpire is part of the field of play. That’s just how the rule works. Umpires do their best to get out of the way of batted balls, both for self-preservation and for the integrity of the game. John Bacon wasn’t trying to insert himself into the play; he was in foul territory and focused on getting the fair/foul call right, and there was simply no way to avoid this rip. Bryson Stott couldn’t believe it:

On Tuesday night, while much of the country tuned in to see Kamala Harris debate Donald Trump, I watched an even more lopsided performance from the upper deck at Yankee Stadium, where the Royals’ Seth Lugo utterly dominated the Yankees, holding them to just three hits, walking none and striking out 10 over seven innings in a 5-0 Kansas City win. Through six innings, the only Yankee to reach base was Gleyber Torres, who blooped soft singles into center field on Lugo’s fifth pitch of the game and then, roughly an hour and 20 minutes later, on his 86th pitch; in between, Lugo retired 17 straight hitters. It was the latest in a season full of great outings from the righty, who at 34 years old is having a career year while pushing the Royals toward their first postseason berth since 2015.

Lugo’s seven scoreless frames ran his total to a major league-leading 193 innings while lowering his ERA to 2.94, second in the AL behind only Tarik Skubal. Meanwhile, he’s third in WAR with 4.4, 0.2 behind teammate Cole Ragans, fifth in FIP (3.27), seventh in walk rate (5.8%), and eighth in strikeouts (169) despite punching out hitters at a modest 21.7% rate. He’s also tied with Skubal for the league lead in wins (16), and so by our Cy Young Projection model and its multiple variants, his suite of stats puts him second in the AL to Skubal and a comfortable margin ahead of Ragans, Logan Gilbert, and Framber Valdez. All of this is happening in the first year of a three-year, $45 million contract he signed with the Royals last December, and in just his third season as a starter after largely being typecast as a workhorse reliever during his seven seasons with the Mets (2016–22).

Knocking back a couple of beers from my partial season ticket group’s usual perch in Section 422 affords a different perspective than in the press box or at home. So when Sports Reference’s Katie Sharp noted that the game was the first time the Yankees had ever been held to zero walks and zero extra-base hits while striking out at least 14 times, I decided to take a closer look at Lugo’s night to gain a fuller appreciation of what’s made him so successful lately.

If you’re a major league hitter, you’ll reach a two-strike count. Not every time – baseball isn’t an every time game – but frequently, consistently, inevitably. In those two-strike counts, you’re going to see sliders. Again, not every time, but frequently. A quarter of two-strike pitches in the majors this year have been sliders of some variety. Pitchers are no dummies, and they know where their bread is buttered.

The worst thing that could happen with those two-strike sliders you’re bound to face? A strikeout, obviously. But bad news: There are going to be strikeouts. Again, not every time, but strikeouts are just a fact of life in baseball these days, and 21% of two-strike sliders have resulted in strikeouts this year. Not in the plate appearance – on that pitch specifically. No wonder pitchers throw so many of them.

With all that in mind, here’s a statement I’m sure you’ll agree with: A good way to get better at hitting is to stop striking out on two-strike sliders. I mean, this isn’t rocket science. Striking out is bad. Doing it less is good. Thank you for coming to my TED talk.

Oh, right, I guess I still have to tell you what this article is about. Let’s talk about a player who made a heroic change. Early in his career, he did a fair job protecting against sliders with two strikes (15.4% putaway rate on two-strike sliders). In 2023, though, things took a turn; he struck out on 20% of the two-strike sliders he saw. This year, however, he’s defending against them better than ever. No player in baseball has gone down less frequently against two-strike sliders than our mystery man’s 8.6% clip. Pitchers simply can’t get him out. He’s putting up a glorious 118 wRC+ and striking out less often than last year.

Before I started researching this article, I assumed that Cal Raleigh had been an All-Star before. I was wrong. Raleigh is in just his third full season as a big leaguer, but he’s spent all of that time as one of the best catchers in baseball, so I was surprised to find out that the last time he won an award of any kind was 2019, when he was named the California League’s Rookie of the Year as a member of the Modesto Nuts. Now that I know, I feel even stronger about the premise of this article, so please forgive me for stating it so baldly: Cal Raleigh is a star, and it’s about time we all acknowledged it.

Raleigh has turned on the afterburners over his last nine games entering Wednesday, slashing .314/.390/.629 with three home runs for a 187 wRC+. With that, he pushed his WAR to 4.3, tying his total from the 2023 season. According to WAR, he was the sixth-best catcher in baseball in 2022, the fourth best in ’23, and he’s now the second best in ’24. Unless my pattern recognition skills have fallen off since elementary school, next year he’ll have to find a way to be number zero.

Here’s what Kevin Goldstein wrote in June 2021, just a bit over a month before Raleigh made his big league debut:

Teams were almost universally enamored with Raleigh’s bat in the 2018 draft, but the Florida State product fell to the third round because most had big concerns about his ability to stay at catcher, projecting a quick move to first base, where the pressure on the player to hit increases exponentially. The Mariners decided to at least try to keep him behind the plate, and to the player’s credit, Raleigh has put an incredible amount of work into his defense, and suddenly looks like an average defensive catcher.

As it turned out, Raleigh struggled mightily at the plate during his 43-game rookie stint with the Mariners, but his defense graded out great. In that short sample, both FRV and DRP rated his framing highly, and DRS would hop on board the following season. This year, in an uncommon bit of perfect harmony, all three of those advanced defensive metrics agree that Raleigh is having his best season ever behind the plate. DRP says he’s saved 17.5 runs, DRS has him at 17, and FRV at 13, all of which are good enough to rate him the best defensive catcher in the American League and second best in the game, behind Patrick Bailey.

Raleigh has paired that defensive excellence with the classic profile of a power hitter. He strikes out too much, but when he does make contact, look out. That’s not to say that he’s out of control: This year, he’s been especially aggressive on pitches over the heart of the plate, so despite his elevated chase rate, he ranks in the 80th percentile in Robert Orr’s SEAGER metric, which measures selective aggression. Opposing pitchers, hopeful that they can induce a chase and terrified of what might happen if they hit the zone, are throwing Raleigh a lot of balls, and he’s running a career-high 10.8% walk rate despite striking out nearly 30% of the time.

Even with the higher walk total, Raleigh’s profile still depends much more on power than his on-base ability. First, as befits a catcher nicknamed Big Dumper, he doesn’t beat out too many hits, which drives down his batting average. More important is the way Raleigh swings. He doesn’t just have the profile of a classic power hitter; he’s got the elevate-and-celebrate profile of today’s power hitters. He specializes in barrels, hitting the ball hard and lifting it like few others. His 53% fly ball rate is second among qualified players, and for the third season in a row, he’s in the 94th percentile or better in pulled fly ball rate. If you take a quick glance at his spray chart, you’ll see home runs to all fields, and you’ll think, “What a balanced batted ball profile.” And then you’ll remember that he’s a switch-hitter. Raleigh is looking to lift the ball and yank it from both sides of the plate. His 30 homers are tied for 12th in baseball, but his 25 pulled homers are good for third. On the left is a spray chart that shows all of Raleigh’s career homers to the pull side and straightaway. On the right is a chart that shows his opposite field home runs.

This year, Raleigh’s 30 homers lead all catchers. He led all catchers with 30 last season too, and despite appearing in just 119 games and playing through a broken thumb and a torn ligament in his catching hand for more than a month, he also led all catchers with 27 in 2022. Only eight players have ever put up three 27-homer seasons while catching at least half the time. Here’s the list of players who have done it three times in a row: Lance Parrish, Mike Piazza, Johnny Bench, and Cal Raleigh. If you’re keeping score at home, that’s one eight-time All-Star, two inner-circle Hall of Famers, and Cal Raleigh, who again has never had a full season when he didn’t hit at least 27 homers. Among catchers with at least a thousand career plate appearances, Raleigh’s .227 ISO ranks fifth all-time, and his 144 ISO+ ranks 13th.

Put all that together, and Raleigh combines first-rate defense with a homer-heavy 109 career wRC+ (115 over the last three seasons). That’s a pretty compelling package, and it’s made Raleigh the second-best catcher in baseball no matter what timeframe you look at.

Our entire database shows 278 four-win seasons from 106 different catchers. Along with Raleigh, I counted just 20 who had put up three in a row, and the list once again reads like a who’s who of Hall of Famers, along with more recent framing standouts.

I’m not trying to say that Raleigh is destined for the Hall of Fame. I’m just trying to demonstrate that what he’s been doing doesn’t happen all that often, especially right out of the gate. From the moment he became a full-time starter, Raleigh has been one of the best catchers in baseball, and despite playing through injury at times, he’s been hands-down the most consistent. There’s no guarantee that this will continue. It’s hard to stay on top defensively, especially because catching techniques have changed radically in the last few years. Look at J.T. Realmuto, who was one of the league’s premier defenders for years, and then suddenly saw his framing fall off out of nowhere last season. It also looks more and more likely that the ABS system will be coming soon in some form to erase at least part of a catcher’s framing value. If nothing else, that just means that we should appreciate Raleigh’s current greatness all the more. He belongs in any conversation about the greatest catchers in the game right now, and it’s time he had the hardware to prove it.

The last time Luis Arraez struck out was August 10, a full month ago. He struck out the day before that as well. As of Tuesday morning, Arraez has played in 42 of the Padres’ 46 games during the second half of the season, and he has struck out exactly twice. No other qualified player has struck out fewer than 15 times since the All-Star break. Please take a moment to think about that. It means that the player with the second-fewest strikeouts has struck out 7 1/2 times more than Arraez. Nearly 75% of qualified players have struck out at least 30 times. Arraez, once again, has done so twice. Here’s what that looks like in a graph. Each bar represents a qualified player and Arraez is the tiny green one all the way to the right. I’ve added a dashed line to give you a sense of how far below everyone else he is.

Arraez currently has 26 strikeouts over the entire season. If he can stay below 30, he would be just the ninth qualified player in this century to accomplish the feat, and the first since Jeff Keppinger did so in 2008. Even if you do count 2020, despite the fact that Arraez has made 340 more plate appearances (and counting) than any player in that season, he currently has fewer strikeouts than all but five of the 142 qualified players. Here’s a chart of the whole 2024 season, just for good measure. Read the rest of this entry »
