With the playoff fields in both leagues nearly set, we here at FanGraphs are turning our focus to how teams set up for October. Jay Jaffe has covered the best players at each position among the contenders, with a run down of the worst positions in each league still to come. Dan Szymborski looked into the particulars of playoff lineup construction. Inspired by Meg Rowley, I’m taking a different tack: I’m looking for the players, strategies, and matchups that could be the difference between success and failure for each team.
We already know who the best players in baseball are, and they will of course be hugely important in the postseason. But less heralded players frequently have a lot to say about who takes home the World Series trophy. Think Steve Pearce and David Freese lengthening their respective lineups to turn those offenses from good to great, or the Braves bullpen mowing down the opposition in 2021. (On the flip side, you don’t hear a lot about teams let down by their supporting casts, because they mostly lose early on.) The best players aren’t always the most pivotal. In that spirit, I went through each team and focused on one potential pivot point. I’m looking at the American League today, with the National League to follow tomorrow.
New York Yankees: Austin Wells, Jazz Chisholm Jr., and Giancarlo Stanton
It’s not hard to come up with a game plan against the Yankees offense. It involves putting giant red boxes around Aaron Judge and Juan Soto, who have been the two best hitters in baseball this year, and writing “don’t let these guys beat us” in bold lettering beneath those boxes. The Yankees have the best wRC+ in baseball, all while their non-Judge/non-Soto hitters have combined for a 93 wRC+, the rough equivalent of the Washington Nationals. Sure, every team would be worse without its two best hitters, but not this much worse. Every pitcher who faces New York will have spent the vast majority of their preparation time looking at Judge and Soto, and building everything around that.
The easiest way to overcome Soto and Judge is to avoid them. I don’t mean intentionally walking them every time, though I’m sure Judge will receive his fair share of free passes. But teams will try to get those two to chase and avoid giving in even when behind in the count against them, which will result in plenty of walks the natural way. There’s going to be a ton of traffic on the bases for the team’s number four hitter, either Austin Wells or Jazz Chisholm Jr./Giancarlo Stanton depending on the matchup.
Wells has hit a rookie wall in the last month, with an 18 wRC+ in the last 30 days. Righties have simplified their attack against him, hammering the zone with fastballs and then aiming sliders at his back foot. This feels like the kind of slump that’s part fatigue and part adjusting to the majors. Wells hasn’t been aggressive enough on early-count fastballs (his swing rate on in-zone fastballs in the first two pitches of an at-bat has fallen from 64% to 54%), and so pitchers are taking the invitation to get ahead. Given how many runners tend to be on base in front of him, that approach will probably continue. It’s up to him to make opposing pitchers reconsider.
Chisholm and Stanton have split reps as the Judge follower with a lefty on the mound, and I’m not sure who will end up with the job. Like Wells, Chisholm has been too passive on early-count fastballs in his protection role, and he’s getting some tough counts and chase pitches as a reward. Still, I’m more optimistic about his outlook than Wells’. Chisholm might be taking fewer swings at crushable pitches, but he’s laying off tough breaking balls too, so it feels like part of a coordinated approach designed to minimize bad swings, and I don’t see an obvious plan of attack here for opposing lefties.
Pitchers attack Stanton high in the zone, where he’s prone to swinging under well-located fastballs. It’s a carnival game, almost: hit the brass ring on the high inside corner, and you’ll win a strikeout. Miss low, and you might surrender a home run. I expect the Yankees to deploy Stanton against pitchers who are less comfortable up in the zone, while Chisholm gets the nod against four-seam specialists.
How these three are able to respond to opposing game plans will go a long way towards deciding the Yankees’ fate this October. It’s a self-reinforcing cycle, too; if these four-spot hitters struggle, teams will naturally become more and more cautious with Soto and Judge, giving more opportunities to the guys behind them. If the four-hole hitters start to click, avoiding the two in front of them becomes less palatable.
Cleveland Guardians: Joey Cantillo and Matthew Boyd
The Guardians have used a simple blueprint to storm to one of the best records in the AL: timely hitting, great defense, and a lockdown bullpen. That’s how you end up with 90-plus wins despite a bottom-five starting rotation, one that looked sketchy heading into the year and lost Shane Bieber almost immediately. Tanner Bibee has been great, and Alex Cobb has been effective when not injured, but the spots after that are up for grabs.
In the past month or so, Joey Cantillo and Matthew Boyd have been the best options. Cantillo, in particular, has shown huge swing-and-miss upside, and he’s done it by using his best pitch, a changeup, more than a third of the time. He still has a fastball-heavy approach, and that pitch is probably his worst, but I expect that to change somewhat in the playoffs. With more off days and more bullpen availability overall, I think the Guardians will ask Cantillo to focus on his changeup and curveball, cut down on fastballs, and pitch twice through the order at max effort. He’s been intermittently great at doing just that, and when he’s on, the Guardians might not need to score much to win.
Boyd joined the Guardians when they were desperate for innings, and he’s been a pleasant second-half surprise. Still, I’m a lot less convinced by his performance than Cantillo’s. Call it the “new is always better” effect, because I’ve seen plenty of Boyd starts over the years and feel like I know what I’m getting at this point. That said, if he can put up average results in a five-and-dive role, the Guardians’ outlook will improve greatly. Their biggest weakness is always going to be the rotation, but Boyd and Cantillo have been great of late, and the rotation has actually been in the top half of baseball in the last month. For one of the weakest offenses in the AL field, improved run prevention would be a huge boon.
Houston Astros: Framber Valdez
The Astros look like a mirror image of the Guardians in a lot of ways. Despite adding Josh Hader, their bullpen has been a weakness thanks to a combination of injuries and regression. The defense isn’t great. But between resurgent bats and a few great starters, they’re putting up early runs and giving their bullpen enough cushion to make things work. Their second-half surge has been keyed by starting pitching in general, and by Framber Valdez in particular.
Valdez had been quietly bad for about a year by the time this All-Star break rolled around. From July 15, 2023 through July 15, 2024, he compiled a 4.13 ERA and 4.01 FIP. He’s always relied on producing a huge number of grounders, but changes in his fastball shape eroded that edge last summer, and it took him quite a while to adjust his game accordingly. His solution has been simple: use his best pitch more frequently. Valdez’s curveball is one of the best in the game, and he’s leaning on it:
More curveballs, more whiffs, more strikeouts, plummeting ERA — he looks like a whole new Valdez. He’s even getting more grounders again, at least partially because hitters are forced to look for the curveball more often and take emergency swings against sinkers. He’s been one of the best starters in the game over the past few months. That’s mostly what people already thought of Valdez – the top starter on a top team – but for a minute there, it wasn’t quite true. Now he looks dominant again, and he’s pitching deep into games too; he’s pitched into the seventh inning in six of his last 10 starts. The Astros could use that combination of length and quality, because if they’re going deep into their bullpen, things could get ugly.
Baltimore Orioles: Jordan Westburg
These don’t all have to be complicated. When Jordan Westburg broke his hand on July 31, the Orioles were a game back of the best record in baseball. Since then, they’ve gone 22-26, and his replacements haven’t impressed. Jackson Holliday hasn’t exactly replicated his nightmare April call-up, but he has a 70 wRC+ since returning to the majors. Emmanuel Rivera has been hitting well, but he’s more of a utility infielder/platoon piece than an everyday starter. Westburg’s presence means that Baltimore’s lineup makes sense; it felt stretched when he was out.
Broken hands are notoriously difficult injuries to forecast. Sometimes recovery is swift and complete. Sometimes power is slow to come back even as everything else rebounds. There’s no strict timeline; we simply don’t know how he’ll look. There’s also the matter of rust. After a brief rehab stint, the O’s activated Westburg over the weekend, but that still means only having about a week to get back up to major league conditioning and form before the games start to count.
Plenty of Baltimore’s hitters have had power outages in the second half — it’s not like you can pin the team’s entire swoon on Westburg’s absence. Adley Rutschman, in particular, looks worn down to me, and Anthony Santander and Ryan O’Hearn have cooled off. But Westburg’s return is a huge potential boost. If he’s back to his former self, the lineup gets scary to navigate. If he’s still not 100%, the other options aren’t amazing. Keep your eyes out to see how he handles inside fastballs, often a tough pitch to deal with if your hand is still hurt.
Detroit Tigers: Performance Against Good Fastballs
The Tigers seem to have worked out a good plan on the pitching front: Let Tarik Skubal cook, and fill in everything else with bullpen innings. But that’s only half the equation. They need to score runs, too, and that’s been a challenge this year. They’ve scored the fewest runs of any potential playoff team, and it’s not fluky; they have the worst wRC+ of the bunch, and they’re in the middle of the pack when it comes to baserunning.
To make matters worse, the Tigers have been especially weak against good fastballs. Only five teams in baseball have done worse against fastballs 96 mph and above this year: the Rockies, White Sox, Blue Jays, Marlins, and Rays. (They’re also bad against fastballs 95 and above, to be clear – 96 just feels like the new definition of “hard fastball” as velo keeps creeping up.) That’s not good company to keep, and the playoffs are chock full of hard fastballs. In the 2023 regular season, 10.4% of all pitches were fastballs thrown 96 mph or harder. In the playoffs, that crept up to 15.5%. Teams with hard-throwing relievers make the playoffs more often, and they also use their best relievers more while asking their starters to throw harder in shorter bursts in October. If you’re weak against velocity, teams will come after you.
Spencer Torkelson has had well-publicized struggles against hard stuff. Matt Vierling, Jace Jung, and Trey Sweeney, all of whom will start plenty in the playoffs, have looked overmatched this year against very good heaters. Kerry Carpenter and Colt Keith are doing damage against them, so look for opponents to attack the lefty-heavy heart of the Detroit lineup (Carpenter, Keith, and Riley Greene) with secondary-heavy lefties and then bring the thunder against everyone else. The Tigers are going to see a lot of fast pitches in the strike zone. If they can’t handle them, it might make for a short October run. If they can, their offense will surprise to the upside.
Kansas City Royals: GB/FB Ratio Allowed
The Royals are one of the best defensive teams in baseball, and the eye test and defensive models agree. But while the Bobby Witt Jr.-led infield is outstanding, the outfield is more of a mixed bag. Center fielder Kyle Isbel has been great in 2024, but he’s not getting much help. Tommy Pham is a hair below average in right, hardly surprising given that he’s 36. MJ Melendez is one of the worst defensive outfielders in baseball. Isbel covers so much ground that he can make up for some shortcomings, but one man can only run so fast. Think of it this way: Per Statcast, Kansas City’s infield defense has been 31 outs above average. Their outfielders have been three outs above average, and that’s with Garrett Hampson putting in solid work in left when Melendez isn’t available. The Royals’ preferred lineup is light on outfield defense, in other words.
The Royals pitching staff isn’t particularly focused on grounders, though. They’re in the middle of the pack when it comes to GB/FB ratio, and Brady Singer is the only one of their playoff starters who effectively keeps the ball on the ground. Opposing teams will be looking to elevate against the Royals, keeping the ball away from Witt’s all-encompassing glove. That might go double in Kansas City, where Kauffman Stadium’s cavernous confines mean that balls in the gap can travel a long way. Isbel is so good that he can cover for some of the corner deficiencies, but if the Royals’ opponents can pepper the pull side in the air, Kansas City’s defensive excellence will be blunted.
Minnesota Twins: Bridge Relievers
Let’s throw in the Twins as a bonus, even though they’re out of playoff position at the moment. They’re two back in the loss column with four left to play, which doesn’t leave them much margin for error. On the bright side, though, they hold the tiebreaker over both the Royals and Tigers, which gives them an outside chance at sneaking into the field if either of their divisional rivals hits a banana peel in the last series of the year. We give them a 22.8% chance of making the playoffs, which feels like enough of a shot to include in this article.
The business end of the Minnesota bullpen is fearsome. Jhoan Duran isn’t having his best season, but he’s clearly one of the better closers in the game. Griffin Jax has been outstanding. He has five plus pitches and is commanding them well, absolutely overwhelming opponents in the process. He might end up as the most valuable reliever in baseball this year when you consider volume, leverage, and results.
Should the Twins make the postseason, Duran and Jax are going to be very busy. But they can’t pitch all of the relief innings, and the guys behind them are question marks. Louie Varland has a 5.79 FIP (don’t even ask about the ERA, it’s ugly) and is coming into bigger spots than any Minnesota reliever aside from the top duo. Cole Sands has had an up-and-down season, and we consider him their secondary setup man after Jax. Scott Blewett and Ronny Henriquez have seen their strikeout rates plummet to borderline unplayable levels. Caleb Thielbar is dancing on a knife’s edge between effectively wild and unable to find the zone.
To be clear, this isn’t a case of an unfixably bad unit. I think Thielbar is an impact lefty when he’s right. Varland has premium stuff. Henriquez’s changeup is a weapon. Starting with Duran and Jax is a huge tailwind. It isn’t hard to imagine a world where some of the bullpen options pop and the Twins suddenly have a dominant relief corps.
But that hasn’t happened this year. Minnesota’s bullpen is playing its worst baseball of the season over the past few weeks – they have a 4.80 ERA even with the two top options taken into account, and a 5.33 without them. The middle innings are feeling shakier than ever, and that’s particularly concerning given that the starting rotation has been covering fewer innings since Joe Ryan hit the IL. If this group rises to the occasion, the Twins will look like a completely different team than they have so far this September. But, uh, that’s kind of the problem: Right now they don’t look very good.
