The key decision point in Saturday night’s Mariners-Tigers game came in the fifth inning, when manager Dan Wilson left righty George Kirby in the game to face a dangerous lefty, a third time through, with a runner on base. Kerry Carpenter smacked a 400-foot homer, erasing a Seattle lead, and the Tigers won 3-2 in 11 innings. So on Sunday, when righty Luis Castillo found himself in a similar pickle, Wilson found himself in a bind of his own.

The situation: a Gleyber Torres single put runners on first and third with two outs in the fifth inning. The next batter? None other than Carpenter. For the second straight day, the Mariners held a 1-0 lead, and this time, further runs didn’t feel likely, not with Tarik Skubal on the mound. Castillo had bobbed and weaved his way through the Tigers lineup two straight times, but he’d thrown 85 pitches to do so, scattering four walks and that Torres hit through his 4 2/3 innings.

This was no easy decision. Each choice had several points in its favor, but several downsides as well. Why pull Castillo? The situation greatly disfavored him. He’s far better against righties than lefties, and his platoon splits have only increased since he moved to Seattle and started weaning the changeup out of his arsenal. Even worse, Carpenter was up for a third time and had already seen 10 pitches from Castillo, including everything in his arsenal. Carpenter himself has huge platoon splits; in his career, he’s faced righties six times as often as lefties, with a 138 wRC+ against righties and a 69 wRC+ against lefties. Gabe Speier, Seattle’s middle-inning lefty of choice, is outstanding against lefties, and generally just outstanding overall. Finally, Castillo didn’t have his best stuff, and certainly didn’t have his best command. A change would meaningfully improve the matchup for Seattle, in the biggest spot of the game.

SEATTLE — “We didn’t steal one. We earned it.” Those were the first words spoken by Tigers manager A.J. Hinch following Game 1 of the ALDS at T-Mobile Park on Saturday night. Hinch took umbrage with a reporter’s characterization of a 3-2 victory that spanned 11 innings in a road ballpark as “stealing one.” Managers should bring that type of bravado to the press conference. Especially Hinch, who is tasked with imbuing confidence in a squad that has been dogged by tales of its epic collapse for over a month.

But with all due respect to Hinch, to describe any one-run, extra-inning game as one where either team definitively earned the win, or on the flip side deserved to lose, places all the emphasis on the final result and glosses over exactly how that result came to be. The Tigers got the win, and now they enjoy a 1-0 series lead with Tarik Skubal, the reigning (and presumptive) AL Cy Young award winner, taking the mound for them in Game 2. They get to bask in the glow of that advantage, and they absolutely should. But if Hinch gets to quibble with verbiage, so do I. Read the rest of this entry »

He doesn’t garner much press — at least not outside of Tigers territory — but Will Vest has developed into one of baseball’s better relievers. The 30-year-old right-hander has appeared in 181 games for Detroit over the past three seasons and logged a 2.93 ERA and a 2.71 ERA over 187-and-a-third innings. Moreover, he is currently the team’s closer. Vest’s 2025 ledger includes 23 saves to go with a 3.01 ERA and a 2.71 FIP, and he recorded the final out in both of the club’s Wild Card wins over Cleveland. If the Tigers go on to beat the Mariners in the ALDS, Vest will likely have played a key role.

He could easily be pitching for Seattle. As related by Dan Hubbs in a piece that ran here at FanGraphs two weeks ago, the Mariners took Vest in December 2020’s Rule-5 draft, only to return him to the Tigers the following July. Hubbs had departed as Detroit’s director of pitching development by the time Vest was reacquired, but he was, and remains to this day, bullish on the righty’s raw ability.

Vest was one of three pitchers (Casey Mize and Tarik Skubal were the others) whose development process the now-Athletics’ bullpen coach looked back on in the September 23 article. Spin rates that were “off the charts” was an attribute Hubbs saw in the then-under-the-radar prospect, as were “good movement profiles on everything he threw.” For the young hurler, success at baseball’s highest level “was just a matter of him getting comfortable competing in the strike zone.“

What are Vest’s memories of working with Hubbs, and in which ways has he continued to develop in the years that have followed? Read the rest of this entry »

Did you know that Tarik Skubal attended Seattle University? What’s that? You knew it already? Oh. Well, that’s great. Kudos to you for doing the research. I hope you are prepared to have that one fact bludgeoned so deeply into your brain over the next week that decades hence, when all the other thoughts start falling out of your aged skull, it will be all that remains. “Seattle Redhawks, only D-I program to offer him a scholarship,” you’ll mutter over and over like a protective spell as you putter through the halls of the nursing home. After defeating the Cleveland Guardians in the Wild Card round, the Detroit Tigers are headed to Seattle for the American League Divisional series. Tarik Skubal is coming home. Let’s get to the preview.

With the second-best record in the American League, the rested Seattle Mariners certainly look to be the clear favorite. They’ve got three (or maybe four) great starters lined up. They’ve got a top-10 bullpen by both ERA and FIP. Their team 113 wRC+ gives them the third-best offense in baseball. They finished the season by winning 17 of their last 21 games. On the other hand, it’s worth noting that all 17 of those wins came against non-playoff teams. Before that 21-game stretch started, the Mariners lost four straight, also to non-playoff teams. Their final act of the regular season was getting swept at home by the Dodgers. The Mariners finished the season with just three more wins than the Tigers and a run differential advantage of just five runs. Their Pythagorean records are identical. These teams are not as different as you may think.

During the Wild Card round, the Tigers were forced to empty their bag of tricks in order to hold off a Guardians team that stole the AL Central crown from under their noses. They relied on their ace, they coaxed just enough great relief performances out of a less-than-great bullpen, they played small ball, they induced errors, they bafflingly pinch-hit for their best hitter. During Game 3, they even got desperate enough to try scoring some runs. Will they come into the ALDS depleted, or will they finally regain the swagger they had when they went into the All-Star break with the best record in baseball? Read the rest of this entry »

Nobody likes a quick exit from the playoffs, but a brief October cameo would have been an especial humiliation for the 2025 Detroit Tigers. After spending much of the season fighting for the league’s best record, and collecting a 14-game divisional lead at one point, the Tigers went nine games under .500 in the second half. Not only was that bad enough to throw away the division title, Detroit nearly missed the playoffs altogether, only squeezing in thanks to a tiebreak advantage over the Houston Astros. So Thursday’s 6-3 win in Game 3 of the Wild Card series must come as a relief, especially given the measure of revenge that comes with beating Cleveland.

Jack Flaherty got the call in Game 3, his first playoff appearance for the Tigers. There had to be some trepidation about Flaherty, given that his last quality start came back in mid-August. While his 4 2/3 innings of work were short on highlight moments, and he allowed three 100 mph liners that fortunately found leather instead of grass or dirt, Flaherty confined the hits to two-out rallies, leaving Cleveland little room for any bunting or other little-ball shenanigans until the fourth inning. A George Valera double and a José Ramírez single got the Guardians on the board in the fourth, but the danger ended when J-Ram was caught stealing and Chase DeLauter hit into a double play. Flaherty did at least avoid angering the cruel deity that governs predictions; last offseason, he famously said that the Tigers would have defeated the Guardians in last year’s playoffs if he hadn’t been traded to the Dodgers at the deadline.

Dillon Dingler is developing into one of baseball’s better catchers. Playing in his first full big league season, the 27-year-old Detroit Tigers backstop banged out 13 home runs while slashing .278/.327/.425 with a 109 wRC+ over 469 plate appearances. Moreover, he was worth six DRS and posted well-above-average framing numbers. His 4.1 WAR ranked third best among junior circuit catchers.

Dingler’s defensive chops extend to his game-calling, which is done in collaboration with Detroit’s pitching group. Preparation is a team strength — last year’s pitching chaos didn’t succeed by accident — and not just because pitching coach Chris Fetter is widely regarded as an adept game-planner. The entire coaching staff is thorough, and so too is the former Ohio State Buckeye, who squatted behind the dish in 115 games this season. (Dingler also filled in at the DH position from time to time.)

The pregame pitcher meetings that precede every game was on my mind when I sat down with Dingler on the final day of the regular season. I was primarily interested in learning how the Tigers go about them, including just what role the catchers play in the dissemination of information. What I found out is that the Tigers — ditto Dingler himself — differ somewhat from most other teams. Not having both catchers in the room, which is the common practice, is an example.

“We do it as the starting catcher, the pitcher, our catching coach, Ryan Sanko, Chris Fetter, and [assistant pitching coach] Robin Lund,” explained Dingler. “That’s pretty much it. It’s usually a smaller group.”

And then there is the preparation he does before the meeting even starts. Read the rest of this entry »

On Wednesday afternoon, I briefly thought that A.J. Hinch had lost his mind. I really don’t know how else to explain it. With runners on the corners and one out in the top of the seventh inning of Game 2 of the Wild Card Series between the Tigers and the Guardians — which Cleveland won, 6-1 — Detroit had Riley Greene, its best hitter, at the plate with a chance to break a 1-1 tie. The Guardians went to the bullpen, bringing in lefty Tim Herrin. Herrin, a 6-foot-6 curveball specialist, figured to be a tough matchup for Greene; he’s been lights out against same-handed batters throughout his career. But then Hinch made a surprising call to the bench. He pulled Greene back and pinch-hit with Jahmai Jones – and now here I am writing this article.

Jones had one key thing going for him here: Like Inigo Montoya, he is not left-handed. He’s also hit lefties much better than righties in his brief major league career, and in his minor league career, too. Greene, on the other hand, is a poor left-on-left hitter. So you can at least see where Hinch’s decision was coming from. I want to give this kind of shocking decision the full consideration it deserves before just laughing it out of the building – after all, what if it was the right call? So let’s do all the math to get an idea of what Hinch was giving up, and what he was getting.

To model pitcher-against-batter outcomes, I first took projections for both players, the granular ones that consider specific outcomes. I also calculated platoon splits for each player by taking their observed career splits and regressing them toward league average based on sample size. I put those two projections – hitter and pitcher – into a modified log5 formula and used it to predict the likelihood of each possible outcome of a plate appearance. Then I applied those outcomes to the game state when Greene’s spot came up in the lineup.

That’s a lot of explanation jammed into one paragraph, so I think an example is in order. Let’s say that the Jones-Herrin confrontation results in a single 25% of the time, a deep fly ball 25% of the time, a strikeout 25% of the time, and a walk 25% of the time. Those are nowhere near reasonable, of course, but just an example. A single would mean runners on first and second (at least) and a 2-1 lead, for a win probability of 73.4%. A deep sacrifice fly? That would get the Tigers to 66.6%. A strikeout? 50.1%. Walk? 65.7%. Average those four probabilities, and the Tigers come out with a 64% chance of winning the game. There are more than four possible outcomes, of course, but this process is how I turn outcomes into win probabilities. Read the rest of this entry »

The first inning was a harbinger. The eighth inning featured an offensive explosion for a team that all too often struggles to score. The Cleveland Guardians plated five runs to break a 1-1 tie and went on to beat a thoroughly frustrated Detroit Tigers team 6-1. The season-saving rally evened the best-of-three Wild Card series at one apiece, setting up a decisive finale for tomorrow afternoon in Cleveland.

The Tigers had their chances. Make that many chances — the first of which came as fans at Progressive Field were just settling into their seats. Parker Meadows pulled a groundball into the four-hole that second baseman Brayan Rocchio could only smother, giving Detroit the first of its 17 baserunners (yes, 17) on the day. Center fielder Chase DeLauter — playing in the first inning of his first big league game — then lost a battle with the sun and wind, dropping a fly ball and giving the Tabbies an early opportunity to open up a lead. Cleveland starter Tanner Bibee survived the little-fault-of-his-own threat. Three strikeouts later, the game went to the home half scoreless.

It didn’t remain scoreless for long. Two batters in, George Valera — a rookie with just 17 major league games under his belt — took Detroit starter Casey Mize deep. It was the first of three Guardians home runs on the day, and while it gave them an early lead, it paled in importance to the two that came later.

One of the game’s biggest plays took place in the fourth inning. With the bases juiced courtesy of a Riley Greene double and a pair of free passes, Javier Báez laced a two-out single to give the Tigers a 2-1 lead… or so it seemed. Zach McKinstry was thrown out trying to go first to third, and the out was recorded just before Dillon Dingler crossed the plate with what would have been the second tally. Initially ruled safe, McKinstry was ultimately determined to be out per video review — this on DeLauter’s first career outfield assist. Read the rest of this entry »

Dansby Swanson brought home back-to-back Gold Gloves in 2022 with the Braves and ’23 with the Cubs while leading the majors in Statcast’s Fielding Run Value in both seasons. Although he hasn’t added any hardware to his collection since then, and while his defensive metrics have slipped, he still grades out as comfortably above average in both FRV and Defensive Runs Saved. His defensive acumen was on display in Tuesday’s Wild Card Series opener between the Cubs and Padres, as he made a couple of pivotal, run-saving plays in Chicago’s 3-1 victory.

The Padres had taken the lead in the second inning, when Jackson Merrill and Xander Bogaerts opened the frame with back-to-back doubles off Matthew Boyd; Bogaerts took third when center fielder Pete Crow-Armstrong’s relay spurted away from Nico Hoerner at second base. Ryan O’Hearn then hit a sizzling 101-mph groundball, and Swanson, who was shaded up the middle, dove to his right to stop it. He looked Bogaerts back to third base, then threw to first for the out. The play loomed large as Bogaerts ended up stranded.

The Padres threatened again in the fourth, when Manny Machado drew a leadoff walk and took second on Merrill’s sacrifice bunt. Bogaerts legged out a chopper into the no-man’s land to the right of the mound for an infield single, and San Diego appeared poised to capitalize when O’Hearn hit a flare into shallow center field. Swanson had other ideas, making a great over-the-shoulder snag of the ball, then in one motion turning to fire home to keep Machado honest.

The first game of the 2025 postseason played out exactly as scripted, plus or minus a few crazy bounces. In the Wild Card series between the Tigers and the Guardians, the aces looked like aces and the offenses looked, well, inoffensive.

Tarik Skubal, who will be picking up his second straight Cy Young in a month or so, carved up the Guardians to the tune of one (barely) earned run over 7 2/3 innings. Gavin Williams, who put up a 3.06 ERA and allowed just six runs over his final five regular season starts, returned the favor, allowing two unearned runs over six innings and change. The two starters combined for 22 strikeouts, with 14 of them coming from Skubal, who earned the win and gave Detroit a 1-0 series lead. Read the rest of this entry »
