The Seattle Mariners are making a change at the top after a season that spiraled far from where anyone in the building expected it to go.
Dan Wilson was informed Sunday that he will not be back next season, according to a report from the Seattle Times. The move comes on the heels of a year that started with real promise and ended with Seattle sitting at 75-86 heading into Sunday’s regular-season finale against the Los Angeles Angels.
That finish looks even harsher when measured against what came before it. Wilson had taken over for Scott Servais in August 2024 and helped steer the Mariners to one of the strongest seasons in franchise history. Seattle won the AL West last year and pushed all the way to Game 7 of the AL Championship Series before its World Series hopes were ended by the Toronto Blue Jays.
With much of that core back in place, another division run seemed within reach.
Instead, the season slipped away.
The Mariners were 36-32 on June 9 and held a three-game lead in the division. They never turned that position into anything lasting, and the standings told the rest of the story. By season’s end, Seattle had fallen all the way into a disappointing collapse.
Wilson will be the one moved out, but the problems were spread across the roster.
Cal Raleigh’s season crashed after his record-setting 60-home run breakout. He entered Sunday hitting .177 with 23 homers. Julio Rodríguez also had his worst offensive season, while deadline addition Taylor Ward never delivered the lift Seattle was counting on.
The injuries didn’t help either. J.P. Crawford and Brendan Donovan both missed time, adding more strain to a lineup that already struggled to hold together.
The pitching staff had its own issues. Andrés Muñoz went into the final weekend with 10 blown saves and a 4.24 ERA. Bryan Woo had trouble on the road, George Kirby allowed 10.2 hits per nine innings, and Bryce Miller posted a 6.05 ERA after the All-Star break.
Wilson also drew scrutiny for some of his pitching calls during the slide, including leaving Miller in long enough to walk seven batters in a 19-2 loss to the Chicago Cubs.
There was another ugly moment too: a 22-0 loss to Milwaukee late in the year.
A managerial change gives Seattle a chance to reset, but it doesn’t erase the bigger picture. The next skipper will walk into a roster with talent, but unless Raleigh, Rodríguez and the pitching staff rebound, the Mariners could be left chasing the same answers again.

J.P. Crawfords Final Mariners Moment Felt Bigger Than One Ovation
J.P. Crawfords final day of the season turned into something more than a routine late-game substitution. The longest-tenured player on the Mariners was lifted in the season finale at T-Mobile Park and greeted with a standing ovation from the home crowd, a fitting nod for a player whose time in Seattle has been defined as much by steadiness and leadership as by production.
Crawford is headed toward free agency, though he has made it clear he wants another run with the club. He finished the year with a .221/.335/.352 line in 116 games, but the numbers only tell part of why teammates and the organization made sure to honor him the way they did. For a team that leans heavily on continuity when it finds it, his departure would leave a familiar space to fill. [Read more 🡒]
Mariners Just Signaled A Dugout Overhaul Fans Cant Ignore
The Mariners have started reshaping the entire dugout structure just one day after Dan Wilsons tenure as manager ended, making it clear this is more than a single personnel move. Seattle announced that bench coach Manny Acta, infield coach Perry Hill, hitting coach Kevin Seitzer, and first-base coach Eric Young Jr. will not return for the 2027 season, a sweeping shift that touches nearly every part of the staff fans see from the field.
President of Baseball Operations Jerry Dipoto and General Manager Justin Hollander framed the changes as part of a bigger reset, saying significant changes are needed as the club looks toward 2027 and beyond. For a team that has spent plenty of time trying to close the gap, the message is plain enough: this is the start of a broader overhaul, and the next set of moves will show just how deep Seattle plans to go.

As Front Office Search Just Took An Unsettling Turn
The Athletics search for a new general manager has taken another twist, and it matters around the rest of the AL West as much as it does in Oakland. Jon Daniels has withdrawn from consideration for the job, choosing instead to stay on as a senior advisor with the Tampa Bay Rays, leaving the As to keep sorting through a broad list of possibilities as they try to find the right fit for a demanding rebuild.
For Seattle, the timing is worth watching because the division picture keeps shifting in the background while other familiar names face uncertainty of their own. Angels manager Kurt Suzukis future remains unsettled, J.P. Crawford is still dealing with injury issues as free agency approaches, and the Astros are weighing Lucas Spences recent form as they sort out their postseason plans. In a division where front-office moves can ripple quickly, Oaklands next hire could end up mattering beyond one clubs search. [Read more 🡒]
