The Seattle Mariners will face the Detroit Tigers with a trip to the ALCS on the line. Seattle has not appeared in the championship series since 2001, and now it stands a single win away, five total wins from an appearance in the World Series. The Tigers have had slightly more recent success, but now find themselves on the ropes in their home stadium. A win forces an elimination game, but Detroit must find a way to get its bats going on Wednesday night.
Luckily for the Tigers, they have the right opposing pitcher to help break out of their semi-slump. Bryce Miller has had a tough season in Seattle, posting a 5.68 ERA and a 1.41 WHIP over 18 starts. He has issues with control and longevity, two areas that the Tigers are excellent at exploiting. It is the biggest start of Miller's life, and it will not be an easy one by any measure.
Opposite Miller is Detroit starter Casey Mize. The righty endured a bit of an up-and-down season, but he leveled out to post a 3.87 ERA and a 1.27 WHIP over 28 appearances. However, his last start against the Mariners was one of the worst of his campaign, as Seattle's lineup tagged him for six runs over just three innings. A similar performance would almost certainly lead to the end of the Tigers' season, a season that once held immense hope for a run far beyond the ALDS.

Mariners vs Tigers Prediction and Pick
Christian Romo of the Detroit Free Press writes, "The Tigers won the game they were supposed to lose in Seattle, and then lost the game they were supposed to win. That still puts them in the driver's seat as they head back to Comerica Park, but it also makes any game going forward very difficult to predict. One consistency about these Tigers so far in the postseason is that the bats are essentially underwater.
Only Kerry Carpenter has an OPS above .800 among Detroit batters with at least 20 plate appearances in the 2025 playoffs, while six of their nine qualified batters currently have a below-average wRC+. That's a formula for failure, especially with Mariners starter Logan Gilbert only giving up three earned runs in his two regular-season starts against the Tigers in 2025. Flaherty will put up another solid start, and the bullpen should be better with rest, but the Mariners will take Game 3 in another low-scoring affair. The pick: Mariners 2, Tigers 1."
