Mariners announce surgeries for Cal Raleigh and Josh Naylor

What happened

The Seattle Mariners announced that catcher Cal Raleigh and first baseman Josh Naylor each underwent surgical procedures on October 3. Raleigh had a left shoulder acromioclavicular (AC) debridement, addressing a joint that had apparently been a factor throughout the season without ever appearing on any injury report. Naylor's procedure was a triangular fibrocartilage complex (TFCC) repair on his right wrist. Per the club's announcement, as reported by Darragh McDonald of MLB Trade Rumors, both players are expected to be ready before spring training gets underway.

Neither procedure had been publicly disclosed during the season, which lends a certain retroactive clarity to what had been a quietly difficult year for two of Seattle's most important position players.

Why it matters

Raleigh and Naylor are not peripheral figures in Seattle's roster construction. Per MLB Trade Rumors, both players are signed to deals guaranteed through 2030 with eight-figure annual salaries. That kind of long-term commitment means the Mariners are not evaluating whether these players fit the next chapter — they are the next chapter. A clean bill of health heading into 2027 is not a luxury; it is a prerequisite for whatever the organization is trying to build.

The timing of the announcements also matters. The Mariners are conducting a managerial search following the dismissal of Dan Wilson, with GM Jerry Dipoto publicly addressing accountability for the club's 2026 performance. Whoever takes over the dugout will inherit a roster whose two highest-profile position players spent the season managing physical ailments that, until now, had not been fully explained. That context shapes how the new manager and front office will approach the offseason and spring preparation.

The shoulder issue Raleigh played through was not previously reported, per MLB Trade Rumors. The wrist soreness that affected Naylor was known to cause him to miss scattered games, but the extent of the structural problem — significant enough to require surgical repair — was not publicly disclosed until the club's announcement.

The numbers

The 2026 season lines for both players tell a story that the surgical announcements now help frame, even if the procedures themselves cannot be cited as a direct cause for the declines.

Raleigh finished 2026 with a .182/.296/.368 slash line and a 95 wRC+. The same player posted a .247/.359/.589 line and a 161 wRC+ in 2025, including 60 home runs. He hit 23 home runs in 2026 — a number that would represent a solid season for most catchers, but was well short of his prior output. His batting average and on-base percentage each dropped by roughly 60 points compared to 2025, per MLB Trade Rumors.

The defensive picture was similarly stark. Raleigh has accumulated 28 Defensive Runs Saved and a 36 Fielding Run Value across his career, but in 2026 he was credited with minus-6 DRS and minus-4 FRV, per the report.

There is a meaningful split buried in those numbers. Before landing on the injured list in May with an oblique injury, Raleigh hit .161/.243/.317. After reinstatement, he hit .193/.324/.397 — still not a line that inspires confidence on its face, but one that carried a 111 wRC+, meaning it was above league average once on-base rate and power were factored in. The oblique was the known variable. The shoulder, apparently, was the other one.

Naylor's 2026 line was .261/.317/.350 with a 95 wRC+. In 2025, he had posted a .295/.353/.462 line and a 128 wRC+. His home run total was cut in half from 20 in 2025, and his walk rate also declined, per MLB Trade Rumors. He did not go on the injured list at any point, but the wrist soreness caused him to miss a handful of games across the season.

From 2022 through 2024, Raleigh averaged roughly 30 home runs per year while hitting a combined .222/.303/.457 for a 117 wRC+, per the report. That baseline — not the 60-homer outlier of 2025, but the steady, above-average production of the three years before it — is the reasonable expectation Seattle is working toward recovering.

Where the club stands

The Mariners finished 2026 at 76-86 (.469), third in the AL West and five games back in the division. They were eliminated from both the division race and the Wild Card race, finishing ninth in the Wild Card standings at 8.0 games relative to the cut line. The club closed the season on a two-game winning streak, which is the kind of detail that feels more like punctuation than momentum.

Seattle fell well short of expectations in 2026, per MLB Trade Rumors. The offseason now opens with a managerial vacancy, two of the club's most important players coming off surgical procedures, and a front office that has publicly acknowledged the need for a reset. On the same day as the Raleigh and Naylor surgical announcements, the Mariners also claimed first baseman Michael Toglia off waivers from the Cincinnati Reds, placing him on the 60-day injured list while he recovers from his own shoulder surgery.

What we don't know yet

The club has not provided specific recovery timelines beyond the expectation that both players will be ready before spring training. "Before spring training" covers a meaningful range of outcomes in terms of how much preparation time each player will actually have, and the offseason between now and February is long enough that any complication would become news quickly.

It also remains unclear how much, if at all, the shoulder and wrist issues shaped Raleigh's and Naylor's 2026 performance. MLB Trade Rumors notes the possibility that Raleigh's shoulder combined with his oblique injury to weigh on his numbers, but that is framed as a possibility, not a conclusion. The club has not drawn that connection explicitly.

The managerial search is ongoing, and it is not yet known who will be leading the team when Raleigh and Naylor report for spring training.

What to watch

The most immediate question is whether both players arrive at spring training on schedule and without restriction. Per the club's announcement, that is the expectation — but the months between now and February leave room for updates in either direction.

Beyond the health picture, the Mariners' managerial hire will shape how the front office frames its 2027 ambitions — and how aggressively it moves to supplement a roster that, even with healthy versions of Raleigh and Naylor, finished 10 games below .469. Per MLB Trade Rumors, Seattle will need both players to produce more in 2027 if the club is to get back into contention. That is the operational reality the new manager will inherit, and the surgical announcements are, in a sense, the first piece of offseason information they will need to absorb.
