Dan Wilson has informed Seattle Mariners players and staff that he will not return as manager in 2027.
The decision came before the season finale on September 27, 2026, following a 75-86 campaign that eliminated Seattle from playoff contention.
Wilson's exit arrives only a year after he guided the club to a 90-win season, an American League West title, and a postseason run that ended in Game 7 of the ALCS against the Toronto Blue Jays.
Regression and Internal Tension
The franchise regressed widely in 2026, with high-profile starters Cal Raleigh and Julio Rodriguez enduring significant slumps.
The pitching staff also struggled to maintain consistency despite a rotation built on high expectations.
Reports from MLB.
com and The Seattle Times pointed to internal tension and a lack of overall accountability from top management down to the clubhouse during the season's low points.
Pitcher Bryan Woo described the leadership dynamic during the difficult season as players struggled on the field.
"Every year is going to take on a life of its own … and learning that, like, it's not the on-field performance that gives guys the leadership and the validation and the voice," Woo said.
"At times where we all have struggled, maybe we didn't feel as confident with speaking up because we weren't performing in our own right.
So it's a tough spot to be in. But I think we all learned from that this year."
Seattle hired Wilson in August 2024 to replace former manager Scott Servais without an interim tag, despite Wilson having no prior professional managerial experience.
Wilson finished his managerial tenure with an overall record of 186-171 across two and a half seasons.
It remains unclear whether he will stay with the franchise in another capacity.
Seattle's front office leadership is expected to remain intact, with president of baseball operations Jerry Dipoto and general manager Justin Hollander set to return to recruit the team's next manager ahead of the offseason.
