Willie MacIver has caught a lot of power arms since entering pro ball in 2018. Some were in Sacramento this season — the 28-year-old University of Washington product spent a chunk of the summer with the Athletics, backing up Shea Langeliers — but none of those hurlers stand out as having the best raw stuff he’s been behind the dish for. That distinction belongs to a former Colorado Rockies farmhand whose brief major-league ledger includes a 22.09 ERA and a 22.7% walk rate over five appearances comprising three-and-a-third innings.

“I caught a guy named Riley Pint,” said MacIver, citing the right-handed flamethrower whom the Rockies drafted fourth overall in 2016 out of an Overland, Kansas high school. “To this day, he has the best stuff I’ve ever seen. I caught him from Low-A all the way through Triple-A, so I was on the ride with him the whole time.”

That ride isn’t necessarily over. Pint is just 27 years old, and while he missed the 2025 season with an injury, the arm is indeed special. MacIver caught him as recently as 2024, and it’s being Pint, and not recent teammate Mason Miller, who he cited speaks volumes.

“When we were in Low-A, it was 102 [mph] all over the place,” MacIver told me. “Then he started throwing a sinker. We were at Driveline together and he was throwing sinkers that were registering as left-handed curveballs on the TrackMan. He could make the ball move like nothing else. His sinker would be like negative-eight, and then he would throw a true sweeper that was Morales-like with the horizontal, but at 87 [mph]. Read the rest of this entry »

SEATTLE — On a per-game basis during the regular season, the Mariners and Tigers both scored and allowed roughly the same number of runs — 4.70 and 4.28, respectively. Through the first four games of the best-of-five ALDS, each team eked out a one-run win and each team triumphed in something of a laugher. Both teams won one game at home and one game on the road, and both teams relied extensively on their bullpens. Heading into Game 5 on Friday night in Seattle, it was clear one team was going to need to do something to distinguish itself. These teams entered the night locked in a dead heat, having played matching hands for much of the series and needing a new strategy, something different to get an edge and break the stalemate, and even then, it required 15 innings and four hours and 58 minutes to do that. When it was all over, the Mariners had outlasted the Tigers, 3-2, on a walk-off single by Jorge Polanco to advance to the American League Championship Series for the first time in 24 years.

“I don’t even know where to begin to try to recap all the heroic efforts that went into today,” manager Dan Wilson said. “And 15 innings? I’ve got to say, I don’t know how the fans kept their energy going. It was unbelievably loud, even in the 15th inning. And this is a special place. T-Mobile Park is a special place, and they showed us that tonight. And just an incredible ballgame from top to bottom.”

Both starting pitchers were taking the mound for a second time in the series, and both brought a slightly different approach to Game 5 than what they put on tape in their prior starts. In Game 1, Seattle starter George Kirby threw his slider 31% of the time; it was the first pitch he threw to eight of the 22 batters he faced. In Game 5, Kirby went to his slider 50% of the time and threw it as the first pitch to 10 of the 18 batters he faced. After the game, he confirmed this was a conscious shift in strategy to show Detroit’s lineup something different from what it’d seen from him six days prior. “All those guys from top to bottom are probably looking for a heater to start,” Kirby said, “and just starting off with a slider, curveball, whatever it may be, just — if I kept them off balance a little bit, I was able to attack the zone a little bit more with my fastball.” By mixing in more sliders early in the count, he was able to maintain the effectiveness of his four-seamer despite the recent exposure. Though the slider-heavy approach meant Kirby racked up fewer strikeouts than usual, he finished his outing allowing just three hits and one earned run over five innings with six punchouts.

Even the best pitchers in baseball lose a game once in a while. Just ask Tarik Skubal. I’m sure you’ve read about it a hundred times by now, but the Mariners have won all three of their games this year where Skubal was the opposing starter. Seattle was the only team to hand him multiple losses during the regular season, and the Tigers dropped Game 2 of the ALDS — technically a no-decision for Skubal — less than a week ago. Now, thanks to his team’s roaring come-from-behind victory in Game 4, Skubal is lined up to start tonight’s decisive Game 5, giving him an opportunity to finally beat the Mariners this year.

I’ll give a warning upfront: This article is going to lean pretty heavily on batter-pitcher matchup stats; we’ll be examining some extremely small samples. But I think it’s an interesting investigation into the strategy that unfolds between familiar foes during a short postseason series.

What I really wanted to know is whether the Mariners had a specific approach that made them so successful against Skubal this year. As I mentioned, Skubal faced the Mariners twice during the regular season. On April 2, in Seattle, he allowed three runs in 5.2 innings; he gave up six hits and three walks while striking out eight. On July 11, he faced them again, this time in Detroit, and allowed four runs in five innings; he gave up just four hits and two walks while striking out five. His Game 2 start this past Sunday was his best yet: He surrendered two runs on five hits and one walk in seven innings while notching nine strikeouts. The two home runs off the bat of Jorge Polanco were his undoing. Read the rest of this entry »

Maybe the three runs the Tigers scored in the ninth inning of their Game 3 blowout loss weren’t so inconsequential after all. Maybe they were a sign of better things to come on Wednesday. Facing elimination, Detroit’s bats woke up in a big way in Game 4 en route to a 9-3 victory. That sends the American League Division Series back to Seattle on Friday for a decisive Game 5, allowing Tarik Skubal one more chance to beat the Mariners for good.

Consider this: Through the first three games of the ALDS, the Mariners had hit more home runs than the Tigers had extra-base hits. Kerry Carpenter hit a home run in Game 1, the team’s lone long ball to that point, and Spencer Torkelson and Gleyber Torres each had a pair of doubles, but that was it. Granted, three of those extra-base hits drove in runs, and two of them tied the game — the Tigers made the most of their limited opportunities — but Seattle had been absolutely outslugging Detroit:

Indeed, outside of Carpenter’s clutch home run, a pair of two-run doubles from Torkelson, and four hits off the bat of Torres, the Tigers offense had been conspicuously absent during the series. Even after their mini-rally in the ninth on Tuesday, Detroit was batting .165 and slugging .233 as a team entering Game 4. On the other hand, Seattle was slugging .423 even while batting just .212 through three games. That narrative completely flipped on Wednesday. The Tigers collected seven extra-base hits (three home runs and four doubles), while the Mariners could only muster one. Torkelson, Torres, Zach McKinstry, and Javier Báez each had multiple hits, and Jahmai Jones had a huge pinch-hit double in the decisive fifth inning.

And as they have all series long, home runs defined the shape of Game 4. Riley Greene had been mostly bottled up during the ALDS; he had collected just two hits through the first three games of the series. His first extra-base hit against Seattle was a 454-foot blast to give the Tigers a 4-3 lead in the sixth inning. After hitting 36 homers during the regular season, his go-ahead home run was the first of his postseason career and broke open the floodgates for the Tigers. For his part, Báez hit his first postseason home run since the 2017 NLCS, a two-run shot, later in the inning. Then in the seventh, Torres continued his hot hitting by launching an opposite field solo shot to extend the Tigers’ lead, making it 8-3.

The game hadn’t started off so lopsided. As they have in each game of the series, the Mariners got on the board first, scoring a run in each of the second, fourth, and fifth innings. With a 3-0 lead halfway through the ballgame, things were looking pretty encouraging for the Mariners. They’ll likely look back on Wednesday and be haunted by some pretty big missed opportunities to put the game away early. In the fourth, Seattle loaded the bases with no outs, but wound up pushing just one run across after a double play and a pop out squelched the threat. The next inning, the first two batters reached, earning the team another run, but the Mariners couldn’t keep the rally going.

Things turned in the bottom half of that inning. Torkelson led off with a single, and after a fielder’s choice, Dillon Dingler drove in the Tigers’ first run with a double. That chased Bryce Miller from the game, and Mariners manager Dan Wilson went with trustworthy lefty Gabe Speier to face the bottom of Detroit’s lineup. Jones, pinch-hitting for Parker Meadows, ripped the first pitch he saw down the left field line to drive in Dingler, and Báez tied the game with a single up the middle in the next at-bat. Speier came back out in the sixth inning to face Greene, but the Tigers left fielder turned on a hanging slider and deposited it in the right field stands. From there, the flood gates opened. The Tigers scored three more in the sixth, capped off by Báez’s home run off Eduard Bazardo, and they added insurance runs in the seventh and eighth.

For Seattle, it’s a pretty concerning shift from what had been a fairly dominant bullpen through three games. Even when you include the three runs allowed by Caleb Ferguson in the ninth inning of Game 3, Mariners relievers had put up a 3.38 ERA and a 1.71 FIP in 13.1 innings during the ALDS — their ERA drops to 1.35 if you ignore those garbage time runs. The Tigers have also scored all of their runs in this series in the fifth inning or later, putting even more pressure on the Mariners’ relief corps.

The runs Speier and Bazardo allowed in Game 4 were their first of the series, and you have to wonder if familiarity is starting to work against Seattle’s ‘pen. Bazardo has appeared in all four games, while Speier has now gotten some high-leverage work in three of the four games, including facing Carpenter and Greene three times apiece. Because Detroit’s most dangerous hitters are left-handed, Speier will almost certainly be called on to work in Game 5 on Friday, and thanks to Ferguson’s struggles on Tuesday — he’s the only other lefty in Seattle’s bullpen — Speier seems like the most critical piece of the pitching puzzle for Wilson and the Mariners.

The Tigers turned to Game 1 starter Troy Melton to shut down the Mariners bats once they had tied it up in the fifth. Melton worked around some trouble in the sixth, getting Randy Arozarena to fly out to center after allowing two two-out baserunners. The right-hander carved through the heart of the Mariners order on seven pitches in the seventh, then erased a leadoff baserunner in the eighth with a made-to-order double play, again only needing seven pitches to set the M’s down in order; he has to have Tigers manager A.J. Hinch feeling really good should the team need a fireman to quell a late rally from the Mariners on Friday. Will Vest closed the door with a 1-2-3 ninth.

While Detroit’s starter for the decisive Game 5 isn’t in question, Seattle’s is still unsettled. Both George Kirby and Luis Castillo could start Friday’s game on normal rest, and both looked pretty good in their earlier starts this series. Ultimately, it’ll come down to who Wilson trusts more to work through the Tigers’ lineup twice, with whoever doesn’t make the start likely available out of the bullpen anyway. I should mention that between the two, Kirby is the only one who has made a relief appearance during his big league career, closing out Game 2 of the 2022 Wild Card series against the Blue Jays.

No matter who starts for the Mariners on Friday, this was the exact scenario they were hoping to avoid. Allowing Skubal two opportunities to affect the outcome of the series is a very dangerous proposition, even if Seattle has beaten him three times this year. Tempting fate a fourth time tips the scales toward Detroit; our ZiPS game-by-game odds currently give the Tigers a 54% chance of advancing to the ALCS (assuming a Kirby start for Seattle). That’s a percentage Mariners fans are well acquainted with.

Water falling from the skies over Comerica Park delayed the start of a pivotal ALDS Game 3 between the Tigers and the Mariners by close to three hours. Once things dried out, Seattle’s batters rained on Detroit’s parade. Eugenio Suárez, J.P. Crawford, and Cal Raleigh all homered, and that was more than enough to support the pitching of Logan Gilbert and four Mariners relievers. When all was said and done, Seattle had an 8-4 win and a 2-1 edge in the best-of-five series.

The game started with a successful challenge. Randy Arozarena was initially ruled safe after Gleyber Torres threw to first to field a comebacker that glanced off of Jack Flaherty’s glove, but replay review reversed the call. Seattle’s leadoff hitter was out by an eyelash. A few swings later, Detroit’s starter had retired the side on just eight pitches. It was to be his only easy inning.

The Mariners made the right-hander work in the second. Josh Naylor had an 11-pitch at-bat, finally grounding out on Flaherty’s first changeup of the evening. Three other batters saw six pitches apiece. Suárez walked, Jorge Polanco and Dominic Canzone fanned, and Flaherty walked off the mound having thrown 29 in the frame, and 37 overall. It was apparent early that the Tigers bullpen would be well-worked by game’s end.

A Dillon Dingler single gave Detroit a runner in the bottom half, but as had happened in the first, Gilbert ended the mini-threat with a strikeout, leaving a Tiger stranded. Never really in trouble over the course of his outing, the tall right-hander nonetheless squelched every semblance of a Detroit rally. Read the rest of this entry »

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.
