What happened: The Seattle Mariners will not participate in the 2026 playoffs. The mathematical elimination occurs just one year after the franchise came within a single game of a World Series appearance.
Why it matters: The outcome cements a disappointing regression for the Seattle Mariners. After entering the year with high expectations, the front office now faces significant roster questions heading into the winter.
By the numbers: The club has struggled with run differential throughout the year, scoring an average of 4.0 runs per contest while allowing 4.4. Seattle has won three of its last five games but could not erase its season-long deficit.
What to watch: The team will play out the remainder of its regular-season schedule before shifting focus to offseason evaluations.
