Cal Raleigh, Josh Naylor undergo offseason surgeries ahead of 2027

What happened

The Seattle Mariners enter the offseason with two of their most prominent position players in surgical recovery. MLB.com's Daniel Kramer reported that catcher Cal Raleigh underwent left shoulder surgery and first baseman Josh Naylor underwent right wrist surgery this offseason. Both players are expected to be fully recovered by Spring Training.

Per earlier Posterior Wire reporting, Raleigh's procedure was specifically a left shoulder AC debridement surgery, performed on October 3rd. That reporting carries the same recovery expectation: ready before Spring Training 2027.

Why it matters

Raleigh has been the organizational cornerstone behind the plate in Seattle, and the catcher position carries a workload that makes shoulder health a legitimate offseason variable. Debridement procedures — the general mechanics of which involve clearing damaged tissue from a joint — are typically considered lower-stakes than reconstructive surgeries, which is consistent with the Spring Training recovery timeline both players carry. That said, the desk is not in the business of projecting outcomes from surgical notes, and the material does not offer a more granular timetable than "fully recovered by Spring Training."

Naylor had his right wrist addressed this offseason. A wrist is the hinge on which a hitter's entire mechanical argument rests, and the fact that the club is moving through this now, rather than carrying it into February, is the operationally relevant detail. The recovery expectation is Spring Training readiness, and that is where the reported certainty ends.

The timing of both procedures, coming immediately after the regular season, reflects standard offseason surgical planning: address what needs addressing while the calendar is most forgiving. Whether either player will carry any limitations into camp, or whether either procedure affects their availability for Opening Day, is not addressed in the material.

Is either player's Spring Training status in doubt?

Not per the available reporting. Daniel Kramer's piece for MLB.com states explicitly that both sluggers are expected to be fully recovered by Spring Training. Earlier Posterior Wire reporting on Raleigh's procedure echoes that framing. Neither player is described as facing an extended absence or a delayed return beyond that window.

What the material does not provide is a specific date, a ramp-up schedule, or any indication of whether "fully recovered" means available for the first workout or available for the first spring game — a distinction that matters more for some positions than others, and matters quite a bit for a catcher.

Where the club stands

Seattle finished the 2026 regular season at 76-86 (.469), placing third in the AL West and finishing 5 games back in the division. The club was eliminated from both the division race and the Wild Card race, and enters the offseason ranked 9th in the Wild Card standings, 8.0 relative to the cut line. The Mariners closed the year on a two-game winning streak — a W2 that, in the context of this particular season, functions more as a footnote than a foundation.

The 76-86 record frames the offseason stakes clearly. This is not a club trimming around the edges of a contender; it is a team that needs multiple things to go right in 2027, and the health of its middle-of-the-order bats is near the top of that list.

The organizational backdrop grows more complicated from there. The Posterior Wire has reported separately that Seattle is conducting a managerial search heading into the 2027 season — a process that was underway as of earlier this week and remains open. Whoever takes that job will inherit a roster that includes two players currently in surgical recovery. The Posterior Wire also reported that the Mariners claimed first baseman and outfielder Michael Toglia off waivers from the Cincinnati Reds as their first offseason addition, a move that adds roster texture but does not resolve the larger questions around the club's direction.

What we don't know yet

The material does not specify what limitations, if any, Raleigh or Naylor will carry into Spring Training workouts. "Expected to be fully recovered" is the reported expectation, not a guarantee, and the desk does not upgrade reported expectations into certainties.

It is also not reported whether either procedure was planned in advance of the season's end or whether it was prompted by something that emerged during the final weeks of play. The October 3rd date for Raleigh's surgery suggests it was scheduled promptly after the season concluded, but the material does not speak to the circumstances that led to it.

The managerial search, meanwhile, remains open. No hire has been reported, and the new manager's relationship to roster construction decisions — including how the club handles the offseason around two recovering players — is entirely unresolved.

What to watch

The most immediate question is whether either player's recovery timeline shifts between now and the start of Spring Training. Both are currently expected to be ready, and the desk will update that framing if the reporting changes.

Beyond the health updates, the managerial search is the organizational thread that runs through everything else. The person hired to manage this club will be working with Raleigh and Naylor as foundational lineup pieces — assuming both return to full health on schedule — and the shape of the 2027 roster around them will depend in part on decisions that have not yet been made, by a manager who has not yet been named, for a team that finished 76-86 and is currently somewhere between retooling and rebuilding.

The offseason, as always, has only just begun.
