ALDS is going 5 games: Mariners lose 9-3 to Tigers in Game 4

The Seattle Mariners couldn’t protect a three-run lead, and now they’ll find themselves in a winner-take-all Game 5 in the American League Division Series.

The Detroit Tigers won Game 4 at Comerica Park on Wednesday, scoring nine unanswered runs after the Mariners jumped out to a three-run lead to avoid elimination and force a deciding game Friday in Seattle.

Detroit Tigers 8, Seattle Mariners 3: Box score

Game 5 will be at either 1:40 p.m. or 5:08 p.m. Friday at Seattle’s T-Mobile Park. If the New York Yankees win the other ALDS Game 4 on Wednesday to continue that series, Seattle and Detroit will play at 1:40, or it will be at 5:08 p.m. if the Blue Jays win Wednesday to clinch a spot in the AL Championship Series.

The Tigers scored three runs in the fifth inning to tie things up Wednesday. Dillon Dingler brought home Zach McKinstry with a double to the gap that Mariners left field Randy Arozarena took a bad route on, allowing the ball to get to the wall.

Seattle then pulled starting pitcher Bryce Miller for left-handed reliever Gabe Speier with the lefty-hitting Parker Meadows due up, prompting Detroit to call on righty-swinging Jahmai Jones to pinch-hit. Jones hit the first pitch he saw for a double to bring Dingler home.

Javier Báez then singled to score Jones and tie the game.

The Mariners stuck with Speier, who had thrown 1 1/3 perfect innings in each of Game 1 and Game 2 last weekend, with lefty-hitting Riley Greene due up to lead off the sixth. Greene crushed a 454-foot home run, the longest at Comerica Park since 2023, to put Detroit up for good.

It was just the fifth home run off of a left-hander this year by Greene, with one of the others also coming against Speier. Greene led the Tigers with 36 homers in the regular season, four of which came against Seattle.

The Tigers poured it on from there, with Báez and Gleyber Torres each homering.

Báe, Detroit’s No. 9 hitter, went 2 for 4 with four RBIs.

Seattle’s offense initially kept things rolling a day after winning Game 3 by a score of 8-4, building a 3-0 lead with a single run in each of the second, fourth and fifth innings.

Dominic Canzone had an RBI single to score Josh Naylor in the second.

The Mariners tacked on another run if the fourth, but it came on a bases-loaded double play hit into by Victor Robles, squandering a chance to add more.

Miller allowed two runs on four hits and no walks over 4 1/3 innings for Seattle.

Seattle right-hander Eduard Bazardo had a rough outing out of the bullpen, allowing three runs on four hits in an inning of work in the seventh.

First baseman Josh Naylor, who had been hitless in the first three games of the series, was a bright spot for the Mariners. He went 3 for 4 with two runs scored and made an unassisted double play in the fourth inning.

The winner of Friday’s game will advance to the ALCS against either the top-seeded, AL East champion Blue Jays or fourth-seeded Yankees, who were the first of the three wild cards from the AL. If the Mariners make it to the ALCS, they would open play Sunday at Toronto if the Blue Jays beat the Yankees. If it’s the M’s and Yankees in the ALCS, Game 1 would be Sunday in Seattle.
