The Detroit Tigers and Seattle Mariners meet in Game 4 of the American League Division Series after trading one‑run decisions in the first 2 before the Mariners got the go-ahead in Game 3 after a significant delay. Detroit posted an 87‑75 record in the 2025 regular season, finishing second in the AL Central. They earned their postseason berth via a wild‑card series win and brought a well‑balanced roster into the playoffs.

Over the final month of the season the Tigers' young core found consistency; they went 18‑11 down the stretch, thanks to improved situational hitting and a bullpen that routinely held narrow leads. Detroit's path to the Division Series included a gritty 3‑2 extra‑inning triumph in Game 1 over Seattle, showing their resilience in tight games. Seattle, meanwhile, captured the AL West with a 90‑72 record, finishing three games clear of Houston.

The Mariners boasted one of the league's best run differentials and used a dominant pitching staff to limit opponents to under four runs per game. After dropping the opener, Seattle responded with a tense 3‑2 win to level the series, demonstrating their knack for timely hitting and their refusal to let the series slip away. The Mariners dominated Game 3, consistently finding success across virtually all innings. Both teams have seen recent games decided by razor‑thin margins, indicating an evenly matched showdown.
