Last year, after a trade deadline sell-off, the Tigers snagged a Wild Card spot thanks to the combination of a late surge and a gruesome collapse by the Twins. This year, it’s the Tigers who are in danger of fumbling away a playoff berth, as they’ve lost 11 out of 15 since September 3, while the Guardians have won 15 out of 18. Meanwhile, the Mets have lost 12 out of 19 this month, slipping from the third NL Wild Card spot to being on the outside looking in due to the tiebreaker with the Reds.

Particularly with that tiebreaker looming so large, with six days to go in the regular season, it’s time for another look at what’s at stake. This used to be Team Entropy territory, but alas in the 2022 Collective Bargaining Agreement, Major League Baseball and the players’ union traded the potential excitement and scheduling mayhem created by on-field tiebreakers and sudden-death Wild Card games in exchange for a larger inventory of playoff games. The 12-team, two-bye format was designed to reward the top two teams in each league by allowing them to bypass the possibility of being eliminated in a best-of-three series. Those bye teams are just 6-6 under the new format, but across a larger sample going back to 1981, research by Dan Szymborski, freshly updated for this article, shows that in matchups where with one playoff team had a layoff of four or more days while its opponent had two or fewer days off, the team with more rest went 27-13 in its next game. It’s an advantage.

Anyway, as we head into the season’s final days, here’s a look at the various scenarios still in play when it comes to playoff seeding, and how the tiebreaker rules could determine who plays on into October and who goes home. Read the rest of this entry »

This June 25, the Dodgers and Tigers both played their 81st game of the season. Both teams finished the day 50-31, sharing the best winning percentage in baseball at .617. The Tigers got there with a slightly better run differential, though; their Pythagorean winning percentage was a cool .608, while the Dodgers checked in at .595. Pythagorean record is implied by runs scored and allowed, and broadly regarded as a more stable measure of talent than simple wins and losses. Since that day, though, the Tigers have gone 35-40 (.467 with a .483 Pythag), while the Dodgers have gone 38-37 (.507 with a .556 Pythag).

I’m bringing this up – last data project for a while, incidentally, I just had a bunch of things in my queue and couldn’t resist tackling them all – because “how good is that team, anyway?” has been a hot topic this year given the various surprising teams who have, at times, taken up the mantel of “hottest in baseball.” Versions of this question – “This team is doing well/poorly now, what does that mean for next month?” – have been both interesting and top of mind in 2025. The Tigers and Brewers played so well for so long that they each crashed the best-team-in-baseball debate. The Mets did their hot-and-cold thing. The Dodgers have endured multiple fallow stretches. Sometimes, teams felt like they were getting very lucky or unlucky relative to their run differential. But what does any of that even mean? Read the rest of this entry »

The Detroit Tigers are in a dogfight with just six games remaining on the schedule. Not only is their lead in the American League Central down to one game over the Cleveland Guardians — their opponent the next three nights — a Wild Card berth is no sure thing if they don’t hang on to win the division. As my colleague Kiri Oler pointed out just yesterday, while their chances are promising on paper, “the error bars on those odds are huge.” In order to stave off what could reasonably be deemed a collapse, a Tigers team that has lost nine out of their last 10 is badly in need of wins down the stretch.

A trio of pitchers who will help determine Detroit’s fate were the subject of a recent conversation I had with Dan Hubbs. Now the bullpen coach for the Athletics, Hubbs was the Tigers’ director of pitching development in 2019 and 2020, a time in which Tarik Skubal, Casey Mize, and Will Vest were all on the doorstep of the majors. Skubal (who made his major league debut in 2020) is slated to start tonight, while Mize (also 2020) will be on the mound over the weekend, and Vest (2021) has a team-leading 21 saves.

Heading into the 2020 season, Skubal was no. 4 on our Tigers prospect rankings with a 50 FV, Mize was ranked no. 2 with a 60 FV, and Vest was no. 36 with a 35+ FV. How did Hubbs view them then, and what does he see from them — albeit from a distance — five years later? That was what I wanted to know.

———

Hubbs on Tarik Skubal:

“With Tarik, it was getting him to command the arm side a little bit more. He was always kind of cross body and ran balls in on guys, and he would pitch up. He’s always had the mindset. I mean, he’s an animal on the mound, and always attacking the strike zone. So, one of the biggest things now is that he commands the arm side. But what has really changed is that he never had the changeup that he has now. That’s taken him to a whole different stratosphere. He throws 100 [mph], then he has this changeup that he can throw against [righties or lefties], interchangeably with his fastball. Read the rest of this entry »

The Boston Red Sox enter the final week of the regular season with a one-game cushion in the AL Wild Card race, which doesn’t sound like a lot, but it is. With Boston and Detroit at 85-71 and Cleveland and Houston at 84-72, with the AL Central and two Wild Card spots on the line, this is a four-goes-into-three situation. Factor in that the Astros have been pretty anemic of late, and the Tigers — who actually end the season with a three-game set at Fenway — look like they couldn’t find their own shoes with a flashlight and a map right now, and you have to like Boston’s chances.

Our playoff odds give the Sox an 89.9% chance of making the postseason. That’s not what I’d consider a lock, but it’s pretty close. Close enough to wonder about what their playoff rotation is going to look like. Read the rest of this entry »

The final week of the regular season is upon us, and the playoff picture in both leagues is far from settled. It should be a fun week of baseball as everything sorts itself out before the postseason begins.

Last year, we revamped our power rankings using a modified Elo rating system. If you’re familiar with chess rankings or FiveThirtyEight’s defunct sports section, you’ll know that Elo is an elegant solution that measures teams’ relative strength and is very reactive to recent performance. To avoid overweighting recent results during the season, we weigh each team’s raw Elo rank using our coin flip playoff odds (specifically, we regress the playoff odds by 50% and weigh those against the raw Elo ranking, increasing in weight as the season progresses to a maximum of 25%). The weighted Elo ranks are then displayed as “Power Score” in the tables below. As the best and worst teams sort themselves out throughout the season, they’ll filter to the top and bottom of the rankings, while the exercise will remain reactive to hot streaks or cold snaps.

First up are the full rankings, presented in a sortable table. Below that, I’ve grouped the teams into tiers with comments on a handful of clubs. You’ll notice that the official ordinal rankings don’t always match the tiers — there are times where I take editorial liberties when grouping teams together — but generally, the ordering is consistent. One thing to note: The playoff odds listed in the tables below are our standard Depth Charts odds, not the coin flip odds that are used in the ranking formula. Read the rest of this entry »

On July 8, the Tigers had 59 wins, while the Guardians had just 42. With one week remaining in the regular season, the Tigers have 85 wins and the Guardians have 84. A single game separates the two teams in the race for the AL Central title, a division that seemed all but sewn up for the Tigers as recently as September 13, when Detroit’s odds to win the Central sat at 98.2%, putting Cleveland’s odds at 1.8%. As of this writing, the Tigers are still favorites to win it, at 62.7%, but given that three of Detroit’s last six games are against Cleveland, the error bars on those odds are huge.

That wild swing in divisional odds happened over the course of the last week, but such a dramatic swing could only occur because in the two months leading up to it, two teams that had been heading in opposite directions both gradually rerouted and wound up on a collision course. Through April 25, both teams were winning games at roughly a .600 clip, but their fates diverged from there. By July 8, the gap in winning percentage had widened to 167 points, which translated to an additional 17 wins for the Tigers compared to the Guardians. Ever since July 8, that divide has slowly evaporated, and now the two teams own nearly identical records. Read the rest of this entry »

By the time the first half of the season ended, Pete Crow-Armstrong appeared to be a lock to join the 30-home run, 30-stolen base club. Elected to start the All-Star Game in center field for the NL in his first full major league season, the 23-year-old phenom had already totaled 25 homers and 27 steals. Things have not come easily since then, however; with one week to go in the regular season, Crow-Armstrong is stuck on 29 home runs, though he does have 35 stolen bases.

It was a fruitful weekend for joining the 30/30 club, with Jazz Chisholm Jr. doing so on Friday, José Ramírez on Saturday, and Corbin Carroll on Sunday; the three of them joined — improbably enough — Juan Soto. This is the fifth season in which four players have attained the dual milestones, and the second in three years, aided by the rules changes that have accompanied the introduction of the pitch clock. Any one of Crow-Armstrong, Julio Rodríguez (who has 31 home runs and 28 stolen bases), Francisco Lindor (28 HR, 31 SB), or Randy Arozarena (27 HR, 28 SB) reaching their needed thresholds would set a major league record.

Although Crow-Armstrong didn’t start against the Reds on Sunday, he came off the bench and had two chances to join the party. He flied out in one and, with the tying run at second base and two outs in the ninth, struck out looking at a borderline four-seamer to end the game. Read the rest of this entry »

Every once in a while, I take a peek at the Kirby Index leaderboards. In August, the expected names that populated the top of the rankings: Kevin Gausman, Trevor Rogers, and Jacob deGrom. Similarly, the bottom featured stereotypically wild hurlers: Joe Boyle, Luis Gil, Freddy Peralta, and… Janson Junk???

If you’re familiar with Junk, it’s most likely due to his excellent command: Among all starters with at least 70 innings pitched this season, his 3.0% walk rate ranks as the lowest. (In an excellent interview with David Laurila last month, Junk talked about training his command at Driveline over the winter.) Seeing Junk in last place on this leaderboard was like spotting a polar bear in Arlington, Texas — in other words, a sign that something was seriously amiss.

By all four components of the Kirby Index, Junk ranked poorly. But his vertical release point was particularly inconsistent, sitting dead last among pitchers in the sample. In my article from last year introducing the Kirby Index, which I linked to above, I found that the ultimate location of the pitch is dictated almost entirely by release angles and release points. It follows that pitchers with inconsistent release points exhibit poor command. How was Junk varying his release point so frequently and still throwing so many strikes? Read the rest of this entry »
