After dispatching the Houston Astros in a two-game Wild Card sweep, the Detroit Tigers’ magical season — their playoff odds sat at just 0.2% on August 11 — continues with a matchup against the Cleveland Guardians in the ALDS. For its part, Cleveland emerged as the winner of the surprisingly tough AL Central, the team’s second division title in the last three years. The Guardians flirted with the best record in the American League for most of the season, but a slow July and August meant that they finished a game and half behind the Yankees for the top seed; they ultimately outperformed their BaseRuns record by 11 games, by far the widest differential in baseball this year, on the back of clutch hitting and a shutdown bullpen.

These two division rivals are well acquainted with each other — Cleveland eked out the regular season series 7-6 — but this will be the first time these storied franchises have met in the postseason. Both teams are extremely young and neither had especially lofty expectations entering the season, but here they are, battling for a spot in the ALCS.

As was true in the Wild Card round, one of the primary questions for the Tigers is how they will deploy their pitching. They got a brilliant start from Tarik Skubal in Game 1 in Houston, then bullpenned their way through Game 2 with the help of seven different pitchers. Now the challenge is figuring out how to take the unorthodox approach that got them through the end of the regular season and past the Astros, and adapt it for the Division Series. Fortunately, the postseason schedule means that Skubal should get two opportunities to pitch this series if it goes all the way to five games, but what they do for the other three games is anyone’s guess.

Both Reese Olson and Casey Mize were on the Wild Card roster, and Detroit will probably bring Keider Montero back for the Division Series. Still, Olson hasn’t pitched past the fourth inning in any of his three regular season starts since returning from a shoulder injury a few weeks ago. Mize, meanwhile, was an effective starter for the Tigers for most of the first half of the season, but missed two months with a hamstring injury and was used as a piggyback option in two of Olson’s starts in late September. The ZiPS game-by-game odds assume that Olson will “start” Game 1, with Montero going in Game 3 and a bullpen game for Game 4:

As you can see, if the Tigers are able to force a Game 5, the series is essentially a coin flip, with the odds slightly favoring Detroit thanks to Skubal. The trick will be to win Skubal’s starts and at least one of Games 1, 3, or 4. Of course, no matter who is listed as the official starter in the non-Skubal games, the Tigers will almost certainly use every available reliever to work through those games. In the Wild Card series, they used eight pitchers out of their bullpen between the two games, with Jason Foley and Jackson Jobe the only ones to allow any runs. Will Vest and Beau Brieske were the standouts, pitching in both games and each earning a save.

The Guardians won’t have to scramble quite as hard to find starters, but the rotation certainly isn’t the main strength of Cleveland’s roster. After Shane Bieber was sidelined by Tommy John surgery in April, Tanner Bibee became the de facto ace of the staff, turning in a solid effort (3.47 ERA, 3.56 FIP, 3.3 WAR) in his second big league season. He improved his strikeout rate by more than two percentage points, lowered his walk rate by 1.5 points, and was a reliable workhorse the entire season. His slider and changeup are both legitimate bat-missing weapons, and his fastball is just good enough to support those secondary pitches.

After Bibee in Game 1, things become a little less clear. Matthew Boyd will certainly make at least one start during the series, and potentially two if Cleveland opts to use him in Game 2 (which would line him up to start a potential Game 5). Boyd returned from Tommy John surgery in August and made eight very impressive starts down the stretch. His fastball velocity is sitting right around where it was at his peak with the Tigers, and his secondary offerings are generating plenty of swings and misses.

For Game 3, the Guardians have a number of options to turn to. The game-by-game odds above assume Alex Cobb will be activated off the IL for this series and make the start, but he’s only made three starts all year and just one in September after dealing with blisters on his throwing hand. Gavin Williams has electric stuff to go along with his prospect pedigree, but he’s struggled with inconsistency, particularly with runners on base, leading to a 4.86 ERA that’s more than a run higher than his 3.67 FIP. There’s also the veteran Ben Lively, whose 3.81 ERA and 4.66 FIP across 29 starts gave Cleveland’s rotation some stability after Bieber’s injury, but he’s not exactly the kind of starter you’d want pitching in a big postseason game. However they lineup their rotation, it’ll be a lot more predictable than the chaos Detroit is trying to harness.

Of course, the Guardians’ true strength lies in their bullpen. Led by Emmanuel Clase, who just had one of the best reliever seasons ever, Cleveland also has a deep stable of setup men who form a bridge from the middle innings to the ninth:

Cade Smith, Hunter Gaddis, and Tim Herrin are as good a setup trio as there is in baseball, and Cleveland’s relief corps as a whole had the sixth-best league- and park-adjusted ERA among the 750 team seasons since 2000. The same expanded schedule that benefits the Tigers’ heavy bullpen usage will also allow manager Stephen Vogt to deploy his ‘pen aggressively should the Guardians take an early lead.

The x-factor on the Guards’ pitching staff is Joey Cantillo, their 13th-ranked prospect. He made his major league debut in late July and has shown some real promise with his changeup and slider, especially across four September starts that saw him pitch to an impressive 2.25 ERA and 1.17 FIP with 29 strikeouts in 20 innings. It’s possible they’ll use him as their Game 3 starter, but it’s more likely that they’ll deploy him as another multi-inning weapon out of the bullpen.

Not only do the Guardians have the more impressive bullpen, they also employ the series’ biggest superstar in José Ramírez. He was a double and a home run away from posting a 40 double, 40 home run, 40 stolen base season, and will certainly receive down-ballot MVP consideration behind Aaron Judge and Bobby Witt Jr. Despite his fantastic track record in the regular season since his breakout 2016, Ramírez has had a rough go of things in the postseason. In 134 plate appearances across 32 playoff games, he’s slashed just .242/.291/.347 (a 70 wRC+) with a pair of home runs. If Cleveland wants to make a deep run in the playoffs, Ramírez will need to be firing on all cylinders.

Steven Kwan and Josh Naylor are the other key members of the Guardians lineup, with the former posting an excellent 131 wRC+ from the leadoff spot while the latter blasted 31 home runs and collected 108 RBIs from the cleanup spot. Both Kwan and Naylor hit left-handed, which puts them at a disadvantage against Skubal. That’s one reason why Cleveland acquired Lane Thomas from the Nationals at the trade deadline — to balance out the lineup with a strong right-handed batter. Thomas got off to a slow start with his new team in August, but produced a 137 wRC+ during the final month of the season.

Cleveland will also hope to see more consistent production out of Jhonkensy Noel. He slumped pretty badly in September, but he was a key member of the lineup during his hot August. His huge raw power gives Cleveland something it has largely lacked the last few years, and one swing from “Big Christmas” could change an entire game.

Because the Tigers will be looking to exploit as many matchups as they can with their relievers, Cleveland’s bench will bear a lot of weight this series:

David Fry, Cleveland’s surprise All-Star, should get starts against the left-handed Skubal, with Noel in the outfield. Beyond those two straight platoons, Vogt will need to pick and choose the right moments to deploy his pinch-hitters to counter A.J. Hinch’s bullpen machinations. The switch-hitting Angel Martínez, in particular, could be the most valuable piece off Cleveland’s bench.

In my preview of the Tigers-Astros Wild Card series, I wrote that Detroit’s offense would need to rely on four key contributors: Kerry Carpenter, Parker Meadows, Riley Greene, and Spencer Torkelson. That quartet collected just four combined hits against Houston, though Meadows’ home run in Game 2 broke the scoreless tie and Carpenter’s single in the eighth started the game-winning rally. Behind those four, the rest of the Tigers lineup collected 13 hits against the Astros, with Torkelson and Colt Keith the only batters to go hitless in the series. Timely hitting was the differentiator; all three runs in Game 1, as well as Andy Ibáñez’s go-ahead, three-run double in Game 2, came with two outs in their respective innings. The Tigers also left a combined 19 runners on base during the series, squandering a number of opportunities to tack a few more crooked numbers on the scoreboard.

The blueprint for both the Tigers and Guardians should look pretty similar: scratch across a few runs early in the game and hand things off to a shut-down bullpen to close things out. With both teams working from the same plan, the series will likely come down to which club can find a timely hit to put themselves ahead. The moves both managers make will have a huge influence on the course of the series. Hinch’s bullpen management has been pretty flawless so far; Vogt will have his own bullpen to manage, along with a bench that should see heavy usage. For fans of nuanced baseball strategy, this series should prove to be a fascinating matchup.

How the New York Yankees choose to deploy Clay Holmes throughout what they hope will be a long postseason run is uncertain, and the same is true for how he’ll perform in whichever role he assumes. The 31-year-old right-hander had a career-best 30 saves this season, but he was also charged with an big league-worst 13 blown saves. Displaced as the team’s closer by Luke Weaver in September, Holmes logged just one save in the season’s final month, that in the club’s last game.

His overall numbers were solid. Over 67 appearances comprising 63 innings, the sinkerballer put up a 3.14 ERA, a 3.02 FIP, and a 25.1% strikeout rate. He also killed a lot of worms, as evidenced by a 65% groundball rate that ranked second-highest among hurlers to throw at least 50 innings, behind only Tim Hill’s 68.2%.

Inducing groundballs has been Holmes’ M.O. ever since he debuted with the Pirates in 2018. He has a career groundball rate of 66.3%, with a high-water mark of 75.8% in 2022, his first full season in pinstripes. (The veteran reliever was acquired by New York from Pittsburgh in July 2021 in exchange for Diego Castillo and Hoy Park.)

As for playoff experience, his résumé is promising. While past performance is by no means a future guarantee, Holmes has nonetheless allowed just three hits over eight innings in six postseason appearances. Given that — and his 74 saves over the past three regular seasons — the 6-foot-5 hurler is battle tested when it comes to late-inning opportunities.

Holmes talked about his signature pitch, and how his approach hasn’t changed much over the years, when the Yankees visited Fenway Park in mid-September.

———

David Laurila: You spent 10 years in the Pirates system before coming to New York. In terms of pitching philosophy — including what was emphasized in the development process — how different was Pittsburgh compared to here?

Clay Holmes: “I think ‘different’ is the key word. The onset of technology has happened pretty fast. To compare what you consider’ best’ and ‘right’ today to ‘best’ and ‘right’ when I was first drafted, you’re talking about two completely different atmospheres and settings in terms of where the game is.

Tuesday afternoon, Josh Hader took the mound at the start of the ninth inning. His Houston Astros were losing 3-0 to the Detroit Tigers in the first game of their three-game Wild Card series. Riley Greene smashed a one-hopper over the right field fence for a double, but Hader retired the other three batters he faced and departed with the three-run deficit still intact.

This was strange! That’s not how teams use their closers. It felt weird right away – to the broadcasters calling the game, to the chatters who flooded us with questions about it, and also to me. And it felt consequential the next day, too, when Hader was summoned for his usual job. This time, the Astros were tied, and there were runners on first and second with two away in the bottom of the eighth. It was the biggest spot in the playoffs for the Astros. Hader walked Spencer Torkelson on four pitches, then threw a fastball right down the middle that Andy Ibáñez tattooed for a bases-clearing double. That made it 5-2 Tigers, and just like that, Houston’s season was over.

If you want to, there’s an easy through-line to trace here. Hader made a low-leverage appearance, and then he had to pitch again on no rest. He didn’t have his best stuff in that second game, so he paid the price. Cause and effect, simple as that. Read the rest of this entry »

For eight innings on Thursday night, the New York Mets’ bats barely spoke above a whisper. Unfortunately for the Milwaukee Brewers, the ninth inning was the charm in Game 3, as the Mets loudly ended the Brew Crew’s 2024 season with a 4-2 win, largely thanks to a dramatic opposite-field homer from Pete Alonso.

The climactic action may have involved a trio of round-trippers, but for six innings, we got a classic pitchers’ duel between two starters with very different styles. Starring for the Mets was Jose Quintana, who played the crafty veteran lefty trope to perfection here, throwing leisurely fastballs and sinkers where hitters could neither drive them or ignore them, while mixing in a healthy dose of changeups and curves that threatened the dirt.

ZiPS was a bit worried about how Quintana matched up against the Brewers coming into the game; while he’s maintained enough of a reverse platoon split over a long career to be confident in it, Milwaukee has a lot of right-handed hitters who can make a southpaw’s evening unpleasant in a hurry. But William Contreras and Rhys Hoskins went hitless, and ultimately it was the lefties who provided most of the team’s offense. It certainly wasn’t from lack of trying; Brewers hitters offered at 60% of Quintana’s fastballs, including more than half of the ones thrown out of the zone. What’s more, they connected with every Quintana fastball they swung at, but it only resulted in two hits. Quintana didn’t throw a single fastball for a called strike all evening.

As Gunnar Henderson stepped to the plate in the bottom of the ninth inning of Game 2 of the AL Wild Card Series on Wednesday night, his team down by a run and one out from elimination, it felt like something special was brewing. Late-inning tension, high stakes, one of the sport’s biggest stars: The postseason was peaking, and the young superstar held the Orioles’ fate in his hands, poised to deliver a signature moment. Unfortunately, he had to deal with Lucas Erceg’s changeup.

I’ve followed Erceg all year, first from afar, mystified by the flamethrower that materialized out of nowhere in the Oakland bullpen, and then with a closer eye when he moved to Kansas City, watching him slip seamlessly into the fireman role in the Royals bullpen. His eye-popping fastball velocity caught my attention, but it’s the changeup stealing the show on the bright October stage.

As the table shows, Erceg’s velocity sits at the top of the scale. His four-seam fastball averages 99 mph. Again, he sits at 99 mph. But the results on it were just so-so: It graded out at 0.1 runs per 100 pitches by Baseball Savant’s run value calculations, neither helping nor really hurting him.

I think the pitch’s performance can be explained by its exceedingly “normal” shape. (Shout out to Leo Morgenstern.) Erceg throws his fastball from a 43-degree arm angle, which is smack dab in the tall part of the histogram among major league pitchers. From that bog-standard arm angle, his fastball gets roughly league-average induced vertical break.

Max Bay’s “dynamic dead zone” application projects how batters might perceive Erceg’s fastball relative to arm angle expectations. While the pitch drifts further to his arm-side than batters might initially expect, the vertical expectations are basically identical. The conventional shape of his four-seam fastball knocks it down a peg from a “stuff” perspective, taking it from plus-plus to maybe just plus.

But a high-velocity fastball doesn’t exist in a vacuum — it exists in the context of all in which it lives and what came before it. In other words, it impacts all of the other pitches in an arsenal. As Erceg rears back to throw, hitters have to keep that 99 mph in mind. And that expectation will certainly help a changeup play up.

The velocity separation between his four-seam fastball and changeup is solid — Erceg’s changeup averages 91 mph — but the horizontal movement of the pitch is its most distinct quality. It averaged 17.9 inches of horizontal movement this season; of the 165 pitchers who threw at least 150 changeups in the regular season, only three averaged more horizontal movement, putting Erceg in the 98th percentile.

Some of that arm-side fade is seam-shifted-wake effects; some of it is connected to Erceg’s motor preferences. (Mario Delgado Genzor wrote a great primer on motor preferences for Baseball Prospectus in January.) Erceg, as far as I can tell, is a pronator, which means that his natural throwing motion is conductive to changeups that run and fade to the arm side. Watch how he whips his forearm toward his body in the slow-motion part of this video:

In these playoffs, at least, it’s been not just the movement that’s exceptional, but his pinpoint command of the pitch. On that 1-2 changeup to strike out Henderson, he buried it in that perfect location right below the knees, where it looks like a low fastball right up until the point that it isn’t.

What makes one changeup better than another is generally one of the more difficult questions to answer in pitching analysis. Royals ace Cole Ragans, for example, had one of the best changeups in baseball this season. Its effectiveness can’t really be explained by its shape — it doesn’t have much depth or movement differential from the fastball. But hitters, time and again, swing through the pitch, deceived by Ragans’ arm action or the way the trajectory mirrors his fastball or some other variable that is impossible to measure. Unlike a fastball, a changeup cannot be easily graded by a stuff model because it depends on how it plays against the expectations of the fastball.

What makes Erceg’s changeup good, however, seems pretty obvious to me. It goes fast and it moves a ton, almost like a lefty slider.

The changeup helps Erceg stand above other relievers with more limited arsenals. Against righties, he is mostly a sinker-slider guy, throwing his two-seamer in on the hands and then dropping his slider below the knees for whiffs. But against lefties, he relies on his four-seamer and changeup, neutralizing lethal lefties like Henderson. The results bear this out — Erceg faced roughly an equal amount of righties and lefties this season and held them both in check (.242 wOBA against righties, .279 wOBA against lefties).

There is a flip side to extreme pronation: It is hard to throw big, sweepy glove-side breaking balls. And yet Erceg’s slider has actually graded out as his best pitch by run value and whiff rate this season. As Erceg’s pitch movement plot shows, befitting his pronation bias, the slider doesn’t actually get any glove-side movement, coming awfully close to achieving a true “deathball” shape. Note the yellow dots representing the sliders he threw this season:

Even without glove-side movement, that shape can still be super effective. When Kumar Rocker made his debut, some analysts were throwing 80 grades on his “deathball” slider. Erceg’s slider is shaped just like Rocker’s, but Erceg throws his a couple miles an hour harder.

Erceg’s top-end velocity, platoon-neutral arsenal, and rapidly improving command (a 14.3% walk rate in 2023, an 11.9% walk rate when Michael Baumann wrote about him in May, and a 4.4% walk rate since that post) suggest to me that he could make a transition to starting pitching. Even if he drops two or even three miles per hour while stretching out to six-inning appearances, the fastball velocity will still be well above average. And if the Royals do decide to go that route, they could accrue significant benefits without risking too much. According to Roster Resource, they have him under team control through the rest of the 2020s, giving them plenty of opportunity to reverse course if it doesn’t work out.

Lucas Erceg, quality major league starter — it’d be quite an ending to a remarkable story. He was drafted by the Brewers as a third baseman in 2016, but after struggling to hit in the high minors before and after the pandemic, Erceg made the switch to pitching. Just 18 months ago, our lead prospect analyst Eric Longenhagen wrote that “his mechanical inconsistency impacts his fastball location,” but noted that Erceg had a “chance to make a consistent big league impact if things click for him command-wise.” He is still so new to this, and so it is easy to imagine what could be.

But all of that is for the future. Right here, right now, in the heart of the playoffs, Erceg is the primary weapon out of a surprisingly solid Kansas City bullpen. And it’s the changeup, in my view, that is setting him apart.

Just before the top of the ninth, with the Astros trailing the Tigers, 5-2, in the second game of the AL Wild Card series, something caught my eye. Several somethings, actually. Will Vest, who despite his more than 200 career appearances has just five saves, was taking a moment on the back of the mound to rub the baseball and breathe. The low third base camera found him, and it was hard to differentiate between the routine, meditative acts that Vest always uses to calm himself before an appearance, and the twitches and tics that might only be surfacing now, during the biggest moment of his career.

When Vest determined that the ball had been sufficiently rubbed, he put his glove back on and tossed the ball into it. He adjusted the left shoulder of his jersey, then his hat, then the right shoulder. He rubbed his fingertips against his thumb and his palm to disperse the sweat, and then rubbed his whole hand against his pants leg. He took shallow breaths as he gently worked his foot into the dirt in front of the rubber. He dumped the ball from his glove back into his pitching hand, then pressed it against his right hip in order to wedge it securely into a changeup grip. He brought his glove to his belly and briefly touched the back of his hand to his butt before nesting it in his glove. He came set, then lifted his left leg ever so slightly and came set again.

I didn’t catch all that the first time; my attention was focused on the background. Those several somethings were flickering in gold, setting off tiny lens flares all around the screen, but because Vest was the hero of the shot, they were out of focus and blurred. I puzzled over what they might be, wondering at first whether the Houston fans were shining their cell phone flashlights, holding some sort of vigil for the team’s flatlining season. It took me a moment to remember the King Tuck crowns. Read the rest of this entry »

Pete Rose died on Monday at his home in Las Vegas, closing the book on an 83-year life that included an incredible, record-setting 24-year major league career that was soon followed by three and a half decades of wandering in a desert of his own making. Handed down by commissioner Bart Giamatti in 1989, his permanent banishment from organized baseball for gambling — a prohibition that dates back to predecessor Judge Kenesaw Mountain Landis’ effort to clean up the game in the wake of the 1919 “Black Sox” scandal — prevented the all-time leader in hits and games played from cementing his legacy with enshrinement in the Hall of Fame, and from working within baseball in any capacity.

Backed by a sizable contingent of admirers and apologists — and a smaller faction of truthers, a group that at one point included Bill James — Rose spent decades denying his transgressions, lying to the public, to baseball officials, and to himself. Deprived of the financial windfall that would have come with election to the Hall, “The Hit King” chose instead to try making a buck with anything he could put his name on. That included everything from a 2004 no. 1 best-selling autobiography, My Prison Without Bars, in which he admitted in print to gambling while managing the Reds (he had done so in pre-publication publicity as well) to autographed balls with the inscription “I’m sorry I bet on baseball.”

That assertion rang hollow given Rose’s apparent lack of contrition, his unwillingness to reconfigure his life as a precondition of his reinstatement by MLB, and his continued lies. Not until 2015 did he admit to gambling during his playing career, after ESPN’s Outside the Lines obtained copies of documents verifying his bets in 1986 while serving as the player-manager of the Reds. Elsewhere during the last decade of his life, a credible allegation of statutory rape dating to the 1970s, uncovered by prosecutor John Dowd during his investigation into Rose’s gambling, undermined his latter-day reinstatement effort while further chipping away at his public standing. It’s been a fall from grace without parallel, at least among baseball’s icons. Read the rest of this entry »
