What to expect in 2026?
Seattle rolls into 2026 as a legitimate World Series threat after a 90-win season, their first AL West title since 2001, and a Game 7 ALCS appearance. Projections are bullish, with models forecasting roughly 94 wins, tops in the American League. It’s also the franchise’s 50th anniversary, adding extra buzz around futures markets.
While the pitching staff slipped to 18th in ERA last year after ranking top three previously, the offense finished ninth in runs scored. If the rotation rebounds even moderately and the lineup maintains its production, Seattle has clear value to repeat in the AL West and make another deep postseason run.
2025 Season Record: 90–72
