Raleigh (left shoulder), Naylor (right wrist) undergo surgeries

SEATTLE -- Cal Raleigh had hinted near the end of the regular season that he may necessitate imaging to address some persistent discomfort that he was playing through.

Josh Naylor was more guarded when directly asked about his status and the visible discomfort he showed with his wrist as far back as June.

It turns out, both sluggers necessitated medical procedures to address their respective issues.

Raleigh (left shoulder) and Naylor (right wrist) each underwent surgery on Saturday at the University of Washington Medical Center, the Mariners announced on Monday. Both are expected to be fully recovered by Spring Training, per the team.

Raleigh underwent a left shoulder acromioclavicular (AC) debridement procedure that was performed by Dr. Albert Gee.

Naylor underwent triangular fibrocartilage complex (TFCC) repair surgery on his right wrist that was performed by Dr. Jerry Huang.

Neither player had been on the club’s injury report that general manager Justin Hollander shares with media at the outset of each homestand, the most recent of which was on Sept. 22.

And the information on Raleigh -- specifically, that he was playing through a shoulder injury that wound up requiring surgery -- is new. It could also explain more of his steep production dip from his historic, 60-homer season in 2025.

Raleigh experienced the sport’s largest dropoff in slugging percentage (down 221 points, to .368) among players with 2.1 plate appearances per team game, while hitting .182 with a .664 OPS, both career worsts since his short 2021 rookie season. However, he did show more consistency down the stretch, with an .824 OPS over his final 25 games.

The shoulder injury was not the only one that he played through. He was placed on the injured list for the first time in his career on May 14 with a right oblique strain and was sidelined for one month. That came after he attempted to play through the oblique issue for two weeks before he re-aggravated it and then was shut down.

The oblique injury was among the Mariners’ more notable of the season. Raleigh was asked about the team-wide injuries after the club was eliminated from postseason contention -- and if they contributed to the club’s shortcomings in an extremely weak American League West.

“No, because every team deals with that,” Raleigh said. “Guys are going to go through aches, pains, injuries. So, it's silly to use that as an excuse. Like I said, 30 different ball clubs -- 29 other different ball clubs -- are dealing with the same thing that we are, and you can't use that as an excuse. And we're definitely not going to. It came down to play on the field.”

Naylor, who just finished the first season of a five-year, $92.5 million contract, echoed the same.

“I think everyone plays through pain,” Naylor said during Seattle’s final homestand. “Everyone wants to play baseball, play at the highest level, and play at your best capability. Whether it’s 50% that day, give all your 50. Whether it’s 20, give your 20. But I don’t really like to use that as an excuse. If you’re not willing to play through pain, this is the wrong job.”

Like Raleigh, Naylor also experienced a sharp decline in offensive production -- specifically via power, which could have been due to the wrist issue. Naylor’s 112-point dip in slugging percentage (to .350) was the sport’s eighth-largest, and he only hit two homers after June 12 and zero after Aug. 8. He was regularly seen wincing after more aggressive swings, dating back months.

Both players were huge catalysts in Seattle winning the AL West in 2025, with Raleigh as arguably the leading storyline in the sport and Naylor coming over in a Trade Deadline blockbuster as a capstone roster piece.

And each is under contract for the next four seasons and is a key piece to the Mariners’ core. The club is obviously banking on both players rebounding from a disappointing 2026 -- and getting healthy to do so.
