Dan Wilson announced after Seattle’s final game of the season that he would not return as Mariners manager in 2027. In an unusual move, he told players and staff before the game, then announced the decision himself to reporters, saying the team’s results had fallen short of expectations.

Seattle finished third in the AL West with a 76–86 record, a sharp decline after winning the division in 2025 and reaching Game 7 of the American League Championship Series. The article cites weaker hitting, inconsistent starting pitching, a late-season bullpen collapse and poor defence, alongside concerns about accountability in the clubhouse. Wilson, a former Mariners catcher who became manager in August 2024, leaves with a 187–171 record; president Jerry Dipoto and general manager Justin Hollander are set to return.
