Raleigh, Naylor both undergo offseason surgeries for Seattle

What happened

Seattle Mariners catcher Cal Raleigh and first baseman Josh Naylor each underwent offseason surgeries, MLB.com reported, with Daniel Kramer writing that both sluggers are expected to be fully recovered by Spring Training. Raleigh had a left shoulder AC debridement procedure performed on Oct. 3, per the Mariners' announcement, while Naylor had his right wrist addressed this offseason. The club announced both procedures.

The timing is notable in the way that most offseason surgical news is: the season just ended, the procedures are done, and the expectation is that neither player will carry the effects into camp. That is the best-case framing, and for now it is the one the club is offering.

Why it matters

Raleigh and Naylor are two of the more consequential bats in Seattle's lineup, and the offseason is already carrying a fair amount of organizational weight. The Mariners finished 76-86 (.469), third in the AL West, and were eliminated from both the division race and the Wild Card race. GM Jerry Dipoto dismissed manager Dan Wilson and announced a new managerial search — a process that was already underway heading into this news, per prior Posterior reporting. Dipoto publicly addressed accountability in the wake of that decision.

Into that backdrop, the club now has two of its core position players recovering from procedures. The expectation of full Spring Training readiness is meaningful precisely because the alternative — a player arriving at camp limited or on a modified program — can quietly reshape a roster before a single game is played. For now, the club's stated expectation is that neither Raleigh nor Naylor will be in that position.

Raleigh's shoulder is the procedure that draws the most operational attention. Catchers and shoulder health occupy a particular corner of baseball anxiety: the position is physically demanding in ways that accumulate, and an AC debridement — a cleanup of the acromioclavicular joint — is the kind of procedure that often reflects wear built up across a season rather than a single discrete event. The club announced Oct. 3 as the date of Raleigh's surgery, which puts the recovery timeline in the hands of the calendar between now and whenever pitchers and catchers report.

Naylor's right wrist surgery carries its own significance for a first baseman whose value is tied directly to his ability to drive the ball. Wrist procedures for hitters are watched carefully because the wrist is so central to bat speed and contact quality. Again, the club's expectation is full recovery by Spring Training, and that is the operative fact here — but it is worth noting that "expected to be fully recovered" is the club's projection, not a guarantee, and the offseason is long enough that the picture could change.

The numbers

The Mariners closed the season at 76-86 (.469), sitting third in the AL West and 5 games back in the division. In the Wild Card picture, Seattle ranked 9th, 8.0 games relative to the cut line — well outside the conversation by the time the season ended. The club carried a two-game winning streak into the close of the year, a small grace note on an otherwise difficult campaign.

Where the club stands

At 76-86, the Mariners were eliminated from both the division race and the Wild Card race before the season concluded. Third place in the AL West is where they landed, and the offseason agenda is substantial: a managerial search is active, the roster has questions at multiple positions, and now two surgical recoveries are part of the planning calculus.

Two days before this news, Seattle claimed first baseman Michael Toglia off waivers from the Cincinnati Reds — their first reported offseason addition — placing him on the 60-day injured list while he recovers from his own shoulder surgery. Under general roster mechanics, a player on the 60-day IL is removed from the 40-man roster count, which gives clubs some flexibility in managing offseason roster construction. The Toglia claim, the Raleigh and Naylor procedures, and the ongoing managerial search are all arriving in the same short window, which is a lot of open threads for a front office to manage simultaneously.

Dipoto's public accountability statement following Dan Wilson's dismissal set the tone for what the Mariners are framing as a reset offseason. The managerial search is the most visible piece of that, but the health of the roster's core contributors is the quieter, equally important thread running alongside it.

What we don't know yet

The club's expectation is Spring Training readiness for both Raleigh and Naylor, but specific return timelines, any activity restrictions during the offseason, or the point at which each player would be cleared for full baseball activities have not been reported. "Expected to be fully recovered by Spring Training" is the stated projection; the details of what that recovery looks like between now and then are not yet public.

On the managerial search: no candidate names, no timeline, and no indication of where the process stands have been reported in connection with this specific news. The search is ongoing, per prior Posterior reporting, and the new manager — whoever that turns out to be — will inherit a roster that includes two players coming off offseason procedures.

It is also worth noting that the details of Naylor's surgery beyond "right wrist" have not been specified in the reporting. The nature of the procedure and any structural findings are not part of what the club announced.

What to watch

The most straightforward thing to monitor is whether either Raleigh or Naylor surfaces with any update on recovery progress as the offseason moves forward. Spring Training readiness is the target; any deviation from that — or any indication that they are on track — would be the next meaningful data point.

The managerial search is the parallel story that will define the offseason's early shape. Whoever Seattle hires will be working with a roster that has Raleigh and Naylor as foundational pieces, and the health of those two players will be part of whatever conversations happen between the new manager and the front office about what the 2027 club can realistically look like.

The Toglia addition, meanwhile, adds a layer of first-base depth to a situation where Naylor's wrist recovery is now a known variable. Whether that connection reflects intentional roster planning or coincidental timing is not something the club has addressed — but it is the kind of offseason overlap that tends to become clearer once the full roster picture takes shape.

For now, the Mariners have announced the procedures, offered the Spring Training expectation, and moved on to the next set of questions. The desk will be watching.
