Mariners manager Dan Wilson unlikely to return in 2027, per Seattle Times

Dan Wilson is unlikely to return as Seattle's manager in 2027, sources told Adam Jude of the Seattle Times, capping a season that began with the Mariners as the American League's most credentialed contender and ends with them watching October from home at 72-83.

What happened

Per the Seattle Times report, attributed to sources speaking with Jude, Wilson's tenure as Mariners skipper is expected to conclude after this season. The club has not made an announcement. Connor Byrne of MLB Trade Rumors reported the story.

Wilson's path to the dugout was unconventional even by baseball's generous standards. A Mariners catcher and a member of the team's Hall of Fame, he returned to the organization as a minor league catching coordinator in 2013. More than a decade later, with no experience on a big league staff, Seattle hired him in August 2024 to replace the fired Scott Servais. He inherited a 64-64 club and guided it to a 21-13 finish — not enough for a playoff berth at 85-77, but enough to earn the full-time job.

His first complete season, 2025, was a genuine success. The Mariners went 90-72, won their first AL West crown since 2001 — a team on which Wilson himself was a starter — and knocked out the Tigers in a five-game ALDS before falling to the Blue Jays in seven games in the ALCS. One win separated Seattle from its first American League pennant. The expectations that followed were, accordingly, enormous.

Why it matters

The gap between those expectations and the current reality is the story of Seattle's 2026 season. FanGraphs had the Mariners at AL-leading 79.6% playoff odds on Opening Day, per the MLB Trade Rumors report. That figure has since fallen to 0.5% with eight games remaining, per the same report. The club is 3rd in the AL West, 6 games back, and ranks 9th in the Wild Card standings at 7.0 games relative to the cut line.

Wilson is not the only one absorbing the consequences of the collapse. Assistant hitting coach Bobby Magallanes lost his job in late July, per the MLB Trade Rumors report, as Seattle's offense — which ranked ninth in the majors in runs scored in 2025 — dipped to 28th this season.

The roster that came so close in 2025 was kept mostly intact this offseason, with one notable addition: infielder/outfielder Brendan Donovan, brought over in an offseason trade with the Cardinals, per the report. Donovan has been limited to 39 games due to injury and has not played since August 21, per the report, removing one of the few new variables from the equation almost entirely.

The numbers

The most dramatic individual decline belongs to catcher Cal Raleigh. In 2025, Raleigh hit 60 home runs, posted 9.1 fWAR, and finished second in AL MVP voting. This season, per the MLB Trade Rumors report, his fWAR has reversed to 1.9, his home run total sits at 22 — 38 fewer than last year — and his wRC+ has dropped from 161 to 94. Center fielder Julio Rodríguez and first baseman Josh Naylor have also fallen well short of last season's production, per the report, though the piece does not attach specific figures to their declines.

Shortstop Colt Emerson, whom Seattle gave an eight-year, $95MM extension before he had played a single major league game, posted a 67 wRC+ across his first 241 plate appearances, per the report. The Mariners were preparing to send Emerson back to Triple-A Tacoma in mid-August when, per the MLB Trade Rumors report, he was placed on the injured list instead. Wrist surgery ended his season roughly a week and a half after that, per the report.

The one number running against the grain belongs to Dominic Canzone, who is posting a 131 wRC+ with 22 HR in 474 PA for Seattle, per earlier Posterior Wire reporting. In a lineup that ranks 28th in runs, that stands out the way a functioning vending machine stands out in an airport terminal — conspicuous, appreciated, and surrounded by things that aren't working.

Where the club stands

The Mariners are 72-83 (.465), sitting 3rd in the AL West, 6 games back, on a one-game losing streak. The Wild Card door is effectively closed at 7.0 games relative to the cut line with the season winding down.

What remains on the schedule has a certain symmetry to it. Seattle travels to Coors Field on Sunday, September 20, where Kade Anderson is the probable starter against Tomoyuki Sugano for Colorado. The Mariners then return home to T-Mobile Park for back-to-back games against the Houston Astros on September 22 and September 23 — the division rival that finished ahead of them in the standings.

What we don't know yet

The Seattle Times report, as relayed by MLB Trade Rumors, is sourced but not an official club announcement. The Mariners have not announced Wilson's status, and the framing throughout the report is that his return is unlikely — not that a decision has been made or communicated publicly. Whether the club makes a formal move before or after the season concludes is not addressed in the report.

The report also does not specify who might replace Wilson, what the front office's broader evaluation process looks like, or whether any other members of the coaching staff are expected to be affected. The departure of Magallanes in late July suggests the organization has already been making mid-season adjustments, but the report draws no explicit line between that move and Wilson's situation.

The underlying causes of the offensive collapse — whether rooted in player regression, coaching, roster construction, or some combination — are described in the report but not formally assigned. Raleigh's drop from 9.1 fWAR to 1.9, and from a 161 wRC+ to 94, is documented; the explanation for it is not.

What to watch

The most immediate question is whether the Mariners make any announcement regarding Wilson's status before the regular season ends. With eight games remaining as of the report, the window is short. A club that went from AL pennant contender to 28th in runs scored in a single offseason will have significant decisions to make about the roster, the coaching staff, and the direction of the organization — and the Wilson question, per the Seattle Times, appears to be the first one approaching resolution.

The Emerson situation will also carry into the offseason. A shortstop on an eight-year, $95MM extension who posted a 67 wRC+ in his first 241 major league plate appearances before a season-ending wrist procedure is a storyline that does not resolve quietly. How Seattle frames his development path heading into 2027 will be worth monitoring.

And then there is Raleigh. A catcher who hit 60 home runs and finished second in MVP voting one year and posted a 94 wRC+ the next is a significant data point for any front office trying to understand what went wrong in 2026 — and what, if anything, is likely to look different next season.
