how far have the mariners gone in the playoffs

The Seattle Mariners have advanced to the American League Championship Series (ALCS) in the 2025 playoffs for the first time since 2001. They won the American League Division Series (ALDS) against the Detroit Tigers in a dramatic 15-inning Game 5 with a 3-2 walk-off victory. The Mariners will face the Toronto Blue Jays in the ALCS following this victory. This is their deepest playoff run since they reached the ALCS in 1995, 2000, and 2001, which are the furthest they have ever gone in the playoffs—they have never reached the World Series.
