The NL West race may have been settled in favor of the Dodgers this year, but everybody goes back to the starting gate in the playoffs. The only difference is the possible extra home game the Dodgers get in each individual series, though home field advantage has been far from a valuable perk for teams except for sales of tickets, hot dogs, and $59 foam fingers. With Los Angeles getting a few extra days to try and heal up a little more, the Padres got here the hard way, having to win the best-of-three Wild Card Series against the Atlanta Braves, a team that still managed to squeeze out 89 wins without Spencer Strider and mostly missing Ronald Acuña Jr.

While some of baseball’s best rivalries are the classic ones that have endured for the last century, such as Yankees-Red Sox and Dodgers-Giants, this one between the Dodgers and Padres is a good example of how new rivalries can pop up and be a lot of fun, too. Despite the fact that the two teams have played in the same division for more than five decades, only in recent years has the so-called I-5 Rivalry really heated up. San Diego has infrequently sustained runs of relevance – this is only the second version of the Friars to string together three winning seasons in a row – leaving Dodgers fans with few nightmares featuring a brown-and-mustard palette. But these Padres have been aggressive, and unlike in the past when short-term bursts of ambition were tempered quickly with brutal fire sales, they’ve consistently tried to make the Dodgers uncomfortable at the top of the NL West. Even as the Padres traded Juan Soto over the winter, they acquired their Wild Card Series Game 1 starter Michael King in that deal and then traded for Dylan Cease, who’ll start Game 1 of the Division Series, just before Opening Day. Yet, ultimate success has proven elusive for San Diego, with two disappointing playoff misses in 2021 and 2023 and still no returns to the World Series since 1998’s debacle.

The Dodgers enter the Division Series with something to prove as well. While they do have a World Series trophy from the COVID-shortened 2020 season, with five 100-win seasons in the last seven normal years, they crave to have more hardware to show for their success. Sure, we’re used to the idea that when you have large playoff formats, winning the World Series takes a lot of luck, but neither fans nor history care much about that. Winning the World Series this year would wipe out most, if not all, of that disappointment; taking care of business in this series would get the Dodgers one step closer to that while also giving them a little revenge against the Padres for knocking them out in the 2022 NLDS, after Los Angeles won a franchise-best 111 games.

So, how do the teams stack up? Let’s start with the ZiPS projections. As I type this, Joe Musgrove has been officially ruled out for the NLDS due to his elbow injury, which has now been confirmed to require Tommy John surgery. That means no Musgrove this postseason – or next season – but for now, we’ll just deal with the impact of the news on this series.

For contrast, here are the projections for if Musgrove had been able to pitch in this five-game set.

Replacing Musgrove with Martín Pérez, likely the next man up, basically flips the win probabilities for Game 4. Where every game previously favored the home team in the projections, now the Dodgers are expected to win on the road against Pérez.

Even though the Dodgers are favored to win with Musgrove out, it would still be wrong to call them overwhelming favorites. This is a close series overall, but also a swingy one, with four of the five games projecting to be at least a 55-45 split, meaning that for the most part, these games aren’t projected to be coin flips despite the tightness of the series as a whole. “Breaking serve” here by winning on the road has quite a lot of value. If the Padres can get to Yoshinobu Yamamoto or Jack Flaherty and win one of the first two games, they would expose one of the Dodgers’ current weaknesses: a thin rotation due to injuries. Walker Buehler had only three quality starts out of his 16 outings since returning from Tommy John surgery in May; his performance was shaky enough that in mid-June the Dodgers optioned him to the minors, where he spent two months trying to get right, before they brought him back up to start on August 20. And despite a superficially appealing ERA, Landon Knack would be about the 12th choice for Los Angeles if everyone were healthy. If the Dodgers are able to get out to a 2-0 lead without any bullpen-exhaustion events, like an 18-inning game, they might be in a position of strength to run a bullpen game and axe one of their uncertain starters from the NLDS rotation.

Where the Dodgers have the advantage is their front-line offensive talent, which gives them what appears to be the superior offense overall, an edge large enough that it isn’t erased if you view players such as Jurickson Profar and Donovan Solano with less skepticism than ZiPS does.

Dylan Cease is a terrific pitcher, but ZiPS thinks the Dodgers’ Big Four of Shohei Ohtani, Freddie Freeman, Mookie Betts, and the good platoon side of Max Muncy has a fighting chance of getting to him. It’s more of an uphill climb against Yamamoto; ZiPS has Luis Arraez as the only San Diego batter projected to have a .300 OBP against Yamamoto, and it gives none of the Padres a .450 SLG projection against him. Now, contrast that with the projections at home against Knack and Buehler.

One of San Diego’s other advantages, at least in the eyes of the computer, is its bullpen. While ZiPS has both teams performing similarly overall, it much prefers the depth of the Padres’ unit. To test their bullpens, in each simulation, ZiPS was instructed to knock out both starters after two innings in one game and have another game last 15 innings; in these scenarios, the odds of the Padres winning the series go from 42% to 47% – nearly a coin flip. In a short series, things like roster construction can make a real difference. Look at the way the Nationals were configured in 2019, with four good starters, two relievers they trusted, and a dumpster fire behind them. That kind of distilled performance meant that even when Washington won 13 fewer regular-season games than Los Angeles that year, ZiPS projected the teams as nearly equal when they met in the 2019 NLDS.

Here’s what I get from these reams of data: The Dodgers should stay the course with what’s worked for them all year, trust their elite hitters, and avoid the temptation to get too cute with their managing tactics, but the Padres ought to be aggressive. If they see an opening to get to Yamamoto or Flaherty, treat that game like it’s Game 7 of the World Series. San Diego can’t afford to save any wacky tricks for later. If the Padres can push the Dodgers back on their heels quickly and early, the latter may run out of time to right themselves.

One thing you’ll hear a lot (in all four series), especially early on, is the claim that the layoff is a big disadvantage for teams. Don’t believe it. If the Padres upset the Dodgers here in the five-game series, it won’t be because Los Angeles was too rested. Instead, it’ll be because the Padres played better.

It would be easy to look at what happened across the two American League Wild Card Series as the best possible outcome for the Yankees. The Astros, the team that had made it to the ALCS in each of the last seven seasons and eliminated New York three times to advance to the World Series in that span, saw their season end after losing to the Tigers; meanwhile, the Orioles, the Yankees’ up-and-coming division rivals who gave them fits all season, were bounced in Baltimore by the Royals.

That’s right, the two biggest AL threats to the Yankees this postseason were knocked out in the first round. To paraphrase manager Aaron Boone, it’s all right there in front of them. Indeed, their path to their first World Series appearance in 15 years is a bit clearer, in the sense that neither their past nemesis nor their latest challenger is standing in their way.

But let’s not get ahead of ourselves here. The Astros look more like the decaying New Rome of Megalopolis than the burgeoning empire that ransacked the AL for the better part of a decade, and Baltimore’s nearly completed rebuild still hasn’t gotten off the ground in October. Besides, the Royals are pretty good in their own right. They have a trio of excellent starting pitchers atop their rotation and a strong group of high-leverage relievers. They run the bases well and are either the best or one of the best defensive teams in the majors. And then there’s shortstop Bobby Witt Jr., a true five-tool player who posted 10.4 WAR this year and has carried Kansas City further than almost anyone could’ve expected when the season began.

To keep going, they will have to overcome the Yankees, who had the best record in the AL and won five of their seven games against the Royals this season. Kansas City’s first chance to do so comes Saturday night, when veteran right-hander Michael Wacha takes on reigning Cy Young winner Gerrit Cole in Game 1 of the ALDS at Yankee Stadium.

It certainly won’t be easy. The Yankees enter this weekend with the best odds of any AL team to win the World Series. Perhaps that makes sense, considering New York won’t have to go through Houston this time, but there’s a more specific explanation for why the Yankees are the team to beat this postseason: This is the best team they’ve had in years.

Wait, these Yankees, who won 94 games and were the second-worst team in baseball for six weeks, are better than the 100-win teams of 2018 and ’19? And the 2022 club that won 99 games? Even the upstart Baby Bombers squad in 2017, the one that many fans still claim would’ve won it all if not for the Astros’ sign-stealing scheme? Really? Sure!

Why? The main and most obvious reason is that the Yankees are no longer just the Aaron Judge show. They have two MVP-caliber talents batting back-to-back in their lineup, and somehow, describing Judge and Juan Soto as “MVP-caliber talents” doesn’t quite encapsulate their excellence or their importance to the Yankees. Think of it this way: The Yankees have both the best hitter in baseball since Barry Bonds and the second coming of Ted Williams. Or put another way, Judge and Soto are the second pair of teammates ever to finish with at least 8 WAR and a 175 or better wRC+. The first pair? Babe Ruth and Lou Gehrig, who did it a ridiculous four times (1927-28, 1930-31).

The rest of New York’s lineup is, at best, inconsistent, but that was the case in prior seasons, too, when Judge was the only player around. In 2022, for example, excluding Judge, the Yankees were roughly league average at the plate (102 wRC+); this season, the Yankees have a 104 wRC+ without Judge. That isn’t much better, but consider where they would be without both Judge and Soto; excluding them, New York hitters have combined for a 92 wRC+. The point here is that the Yankees now have two elite players to lean on instead of just one, and if either Judge or Soto goes cold, the team still has one of the top three hitters in baseball to pick up the slack.

Also, it’s worth noting that Boone acknowledged earlier this week that Judge was pretty banged up during the 2022 postseason, which probably contributed to his struggles (35 wRC+ in nine games); before that year, Judge had a 126 wRC+ across 160 postseason plate appearances. Boone also said both Judge and Soto enter this postseason about as healthy as any player can be after playing a six-month season.

Beyond Judge and Soto, the Yankees also have Giancarlo Stanton, who seemingly levels up when the calendar turns to October. Since joining the Yankees, Stanton is slashing .297/.373/.734 with nine home runs, a .443 wOBA, and a 186 wRC+ over his 75 postseason plate appearances. Additionally, there’s second baseman Gleyber Torres, who had a disappointing contract year this season; he finished with a .257/.330/.378 line, 15 home runs, a 104 wRC+, and 1.7 WAR — all down from his resurgent 2023 campaign. That said, those numbers are pretty remarkable considering how poorly Torres played over the first few months of the season. Entering the All-Star break, he had an 88 wRC+ and 0.3 WAR across 93 games and 380 plate appearances; over his 61 games (285 PA) since then, he has a 124 wRC+ and 1.4 WAR.

The arrival of Jazz Chisholm Jr., for whom the Yankees traded in late July, coincided with their turnaround after their six-week slide. Playing all but 14 of his innings with the Yankees at third base, a position he’d never played professionally before, Chisholm helped shake the team out of its midsummer snooze. With the Yankees, he batted .273/.325/.500 with 11 home runs, 18 steals, and a 132 wRC+ over 191 plate appearances. Thanks to that offense and stellar defense at the hot corner (6 OAA), Chisholm had 2.3 WAR during his 46 games with the Yankees.

This lineup still has plenty of questions, though. Rookie catcher and cleanup hitter Austin Wells had a dreadful September, when he hit for a 22 wRC+ across 83 plate appearances. That probably has something to do with fatigue; through the end of August, Wells slashed .259/.348/.447 with a 126 wRC+. He hasn’t played since the Yankees locked up the no. 1 seed last Saturday, so we’ll see if he rebounds following a week of rest.

The Yankees also have a significant hole in left field, where Alex Verdugo played most of the season and was one of the 10 worst hitters in the majors (83 wRC+). More recently, Jasson Domínguez has started in left, but he’s looked shaky in the field and hasn’t hit much either, though his 84 wRC+ has come in a much smaller sample. Boone has not yet committed to playing one over the other.

Despite the struggles of some players, the Yankees were one of the best hitting teams in baseball overall, ranking third in runs (815), second in wRC+ (117), and first in home runs (237). They’ll face a Royals pitching staff that was one of the best in the majors. Kansas City ranked seventh in ERA (3.76), fourth in FIP (3.76), and third in WAR (20.2). The Royals rotation was especially excellent this season, with a 3.55 ERA and 16.7 WAR, both of which ranked second among all big league rotations.

Their top three starters deserve much of the credit for their success. Cole Ragans, who threw six scoreless innings in Game 1 of the Wild Card round and would’ve kept going if he hadn’t started cramping, broke out this season with a 3.14 ERA, a 2.99 FIP, and 4.9 WAR over 186 1/3 innings — more than 50 innings above his previous career high at any professional level. That workload could become an issue, though. As Ben Clemens noted in his AL Wild Card Series preview, “He’s been walking more opponents and striking out fewer of them in August and September; only a mid-.200s BABIP has kept his ERA from reflecting it.” Ragans is slated to start Game 2 on Monday.

Seth Lugo wasn’t at his best against the Orioles on Tuesday even though he allowed just one run on five hits and struck out six. He labored most of the night and looked gassed when he was removed with one out in the fifth. At 34, Lugo just completed the best season of his career, one that should earn him a top-five finish in the Cy Young voting. He had a 3.00 ERA, a 3.25 FIP, and 4.7 WAR across 33 starts and a whopping 206 2/3 innings, the second most in the majors. One of those starts came last month in the Bronx, when Lugo silenced the Yankees across seven scoreless innings; he struck out 10, walked none, and gave up just three hits. After that start, Jay Jaffe went into depth on Lugo, and I’d encourage you to check out that piece if you haven’t already. Lugo will start Game 3 on Wednesday in Kansas City.

That leaves Wacha, KC’s Game 1 starter, who is having his best season (3.35 ERA, 3.65 FIP, 3.3 WAR, 166 2/3 IP) since at least 2017. Like Lugo, Wacha revived his career last year in the Padres’ rotation and turned that into a multi-year deal with the Royals. In his Wild Card preview, Ben also compared the two Royals veterans to describe Wacha, whom he said “is like Lugo with the volume turned down 5%. He throws a ton of pitches, but his only plus offering is the changeup that made him famous back in his St. Louis days.” Another thing about Wacha? He’s held Judge to just one single and three walks with 11 strikeouts in the 21 times he’s faced the Yankees slugger during his career, for whatever that small sample is worth.

Like the Royals, the Yankees have a deep rotation. Cole missed the team’s first 75 games with an elbow injury, and his first seven starts were the work of a rusty pitcher who might have returned to the mound too quickly. Since the beginning of August, though, Cole has a 2.25 ERA and a 2.62 FIP across 10 starts (60 innings), and for the most part, he’s been even better than those numbers suggest during that stretch. Seven of the 15 earned runs he’s allowed in that span came in his bizarre September 14 start against the Red Sox, when he intentionally walked Rafael Devers with the bases empty. What’s more, only two of the 11 home runs hit off him this year have come within the past two months (in fact, those two homers came in the same start, on August 27 against the Nationals).

Cole is set to start Game 1 on Saturday, followed by Carlos Rodón in Game 2 on Monday. Boone has not yet announced who will get the ball in Wednesday’s Game 3 in Kansas City, but it will most likely be either Clarke Schmidt or Luis Gil, with the other one, along with Marcus Stroman, relegated to the bullpen.

During the second half of the season, Rodón looked more like the pitcher the Yankees thought they were getting when they signed him to a six-year, $162 million deal before the 2023 season. Over his 12 starts since the All-Star break, he is 7-2 with a 2.91 ERA, 3.93 FIP, and 3.67 xFIP. Home runs were his biggest problem this season; his 1.59 HR/9 was the fourth-highest rate among major league starters.

For his part, Schmidt (2.85 ERA, 3.58 FIP, 85 1/3 IP) has been the best Yankees starter on a rate basis this season, but he missed more than three months with a lat strain and has not been as strong since returning from the injured list. After posting a 2.52 ERA and a 3.53 FIP during his first 11 starts (60 2/3 IP), he had a 3.65 ERA and a 3.69 FIP in 24 2/3 innings across his five September starts.

Gil, a Rookie of the Year candidate, dominated during his first 14 starts of the season (2.03 ERA, 3.06 FIP, 80 IP) and anchored the Yankees rotation while Cole was on the shelf. He then looked completely lost for three starts — allowing 16 runs in just 9 2/3 innings — before rounding into form again after making an adjustment to his pitch mix. Over the first half of the season, Gil was mainly a fastball/changeup guy who also had a slider; that worked for the most part. But in early July, after his third straight clunker, he started leaning on his slider more, with his changeup becoming his third pitch.

With the way the ALDS schedule works out — an off day Sunday and then travel days on Tuesday and, if necessary, Friday — both teams will need only three starters to get through the best-of-five series.

Witt is by far the most threatening hitter the Yankees’ staff will face in a lineup that is otherwise fairly light on impact batters. Salvador Perez, who is somehow only 34 years old, is coming off a solid season in which he hit 27 home runs and had a 115 wRC+ while splitting his time between catcher and first base. Expect him to be behind the plate for the entire ALDS as long as first baseman Vinnie Pasquantino remains healthy enough to be in the lineup. Pasquantino, who hit 19 homers and had a 108 wRC+ this season, recently returned from a broken right thumb.

The Yankees bullpen is their biggest question heading into this series. Luke Weaver made a point to say earlier this week that he does not consider himself to be the team’s closer, even though Boone has turned to him in save situations instead of Clay Holmes, who was displaced as the closer last month. No matter what you call Weaver’s role, there’s no denying that he’s been the most impactful Yankees reliever this year. Over 62 appearances spanning 84 innings, he has a 2.89 ERA, a 3.33 FIP, and 1.0 WAR.

Holmes has blown a league-high 13 saves this season, but overall, he’s been solid: 3.14 ERA, 3.02 FIP, 63 IP. Some of his woes can be attributed to bad luck. As David Laurila detailed today, Holmes is still a groundball pitcher, but far more of the fly balls he’s allowed this season have been hit for home runs (11.8%, up from last year’s 7.1%). Opponents also have a .322 BABIP against him; that’s the highest it’s been in a full season. The Yankees’ bullpen also includes righties Tommy Kahnle (2.11 ERA, 4.01 FIP) and Ian Hamilton (3.82 ERA, 3.03 FIP), and lefty Tim Hill, who has a 2.05 ERA and 3.62 FIP in 44 innings since coming over from the White Sox in June.

Closer Lucas Erceg has anchored the Kansas City bullpen since the Royals traded for him at the end of July, and he’s been better than they could’ve expected when they acquired him. Michael Rosen just wrote about what makes Erceg special, and I’ll refer you to his piece rather than going into depth here. Lefty Kris Bubic, their second-best reliever, is also excellent; he struck out 32.2% of the batters he faced this season while posting a 2.67 ERA and 1.95 FIP over 30 1/3 innings. The Royals also feature relievers John Schreiber, a righty, and lefty Angel Zerpa, who replaced Lugo on Wednesday with one out in the fifth to escape a bases-loaded jam. For the first out he recorded, Zerpa threw a sinker that was so nasty that Colton Cowser swung at it even though it hit him.

It’s going to be a fun series. The Yankees are the better team, but the Royals, to quote the face of their franchise, “didn’t come this far just to come this far.” He added, “We’re going to keep getting after it, keep trying to create our own legacy.” What exactly that legacy turns out to be remains to be seen.

The Dodgers built up a formidable seven-game NL West lead over the first half of the season. While they had to withstand a late charge by the Padres — whom they’ll face in a Division Series that starts on Saturday, a rematch of the 2022 pairing that ended up sending a 111-win Dodgers squad home — they were able to do so despite their starting pitching fraying at the seams. Even before Mookie Betts and Max Muncy returned from lengthy absences due to injuries, the emergence of Gavin Lux as an offensive force played a key role in the team’s second-half offensive uptick.

Lux’s overall numbers for 2024 — .251/.320/.383 with 10 home runs — don’t scan as particularly special. Dragged down by a September slump that he began to emerge from during the season’s final week, he finished with a modest 100 wRC+. Based on his overall batted ball data, including a .262 xBA and a .393 xSLG, it’s tough to make the case that he should have done much better. The key point is that he had to hit well enough to get his head back above water after a slow start that looked as though it might cost him his spot in the lineup.

The Dodgers have shown great patience with the 26-year-old Lux, both in the past and this season. A 2016 first-round pick out of a Kenosha, Wisconsin high school, he placed second on our Top 100 Prospects list as a 70-FV prospect four years later (behind only Wander Franco). While he had already debuted in the majors the previous September, he didn’t get a foothold until 2021, and needed a strong September to prevent that season from being a disappointment, though interruptions due to wrist and hamstring injuries probably played a part in his woes.

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.

Lucas Erceg, Filthy 91mph Changeup. ?

Royals Advance. ? pic.twitter.com/kWKQQy0gzZ

— Rob Friedman (@PitchingNinja) October 2, 2024

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:

Lucas Erceg, Wicked 91mph Changeup. 🤢

19 inches of run. pic.twitter.com/pUOkcCQ91Z

— Rob Friedman (@PitchingNinja) October 1, 2024

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.
