Dan Wilson is out as manager of the Seattle Mariners following their third-place finish in the American League West. The move came on the season's final day after a 76-86 record, marking the first managerial change of the 2026-27 MLB offseason. Wilson, hired in August 2024 to replace Scott Servais, entered the season as division favorites coming off a 2025 playoff run that saw the Mariners fall to the Toronto Blue Jays in Game 7 of the ALCS.

Seattle got off to a slow start, winning just four of their first 13 games. With season-long struggles from stars like Cal Raleigh and Julio Rodriguez, coupled with inconsistent pitching, the team never got to more than four games over .500. Wilson acknowledged the difficulty of the season, stating results were not what was expected.

ESPN will track all managerial hirings and firings throughout the offseason, providing potential replacements for every opening as they happen.
