Marcelo Mayer’s rookie season is officially over.

The Red Sox announced Sunday that the 22-year-old infielder will undergo season-ending surgery after suffering a sprained right wrist back in late July. The surgery comes with a three-month recovery timetable and Mayer is expected to be fully healthy in time for the start of spring training.

Mayer said pregame Sunday that he specifically has a torn TFCC (Triangular Fibrocartilage Complex) similar to one he had during the 2022 season, only more severe. He said he knew right away he would likely need surgery but received a shot in hopes of potentially getting back on the field this season.

“I gave it my all, obviously with my options given I could have had surgery when I first injured it or get the shot and try to do everything I can for the slight chance to come back and play,” Mayer said. “Obviously I’m really sad about what’s going on and I want to play, I want to help the team win, but that’s just the hand I’m dealt with right now.”

Mayer suffered the injury on a swing during Boston’s July 23 game in Philadelphia and after receiving the shot attempted to resume baseball activities without success. He said he played catch while the rest of the club was on the road in San Diego, but that he could only throw up to about 60 feet without issue. He also said it hurt to even take practice swings, and the shot only helped for a couple of days before he once again hit a wall.

Eventually it became clear that surgery was the only path forward.

“The way that my wrist is right now there’s just no way for me to come back and play,” Mayer said. “So it made the decision pretty easy to get the surgery.”

The sprained wrist marks the latest setback for Mayer, who has battled injuries throughout his professional career and has seen each of his last three seasons cut short. He battled wrist and back issues throughout 2022, missed the final two months of 2023 with shoulder inflammation and was sidelined from July 31 onward last year due to a lumbar strain. Now he’ll miss the last two-plus months of his first big league season as well.

“It’s frustrating, like I said I just want to be out there playing, I do all I can to put my body in the best position possible and obviously things like that happen in baseball,” Mayer said. “I’m just trying to stay optimistic and try to get after it this offseason and come back stronger.”

Mayer made his MLB debut on May 24 and in 44 games batted .228 with four home runs, 10 RBI and a .674 OPS. While his overall offensive performance didn’t stand out, he provided the club with a huge lift defensively, particularly during the stretch where All-Star third baseman Alex Bregman was out with a quad strain.

Red Sox manager Alex Cora gave Mayer a positive but measured assessment of his rookie season.

“Incomplete. A learning experience. You saw flashes of him offensively, defensively he’s a stud, baserunning-wise he’s great, offensively he still has some learning to do but with experience he was going to get better,” Cora said. “I’m happy he was part of this, he’s a big part of the future of the organization so just get him right, get him ready and we’ll see what happens in the future.”

“I think it’s been a good year, I got to the big leagues, it’s something I always dreamed of doing, obviously there were a lot of goals that I wanted to achieve that I couldn’t with my season being cut short,” Mayer said. “But I mean, this team is super special and I think we have a really good team to make a good playoff run, which is all that matters, that’s all I care about. I’m going to be cheering them on the whole way.”

While losing Mayer will deal a blow to Boston’s infield, Cora believes the team has enough depth to get by. Bregman has played at a high level at third base ever since his return from injury and the Red Sox have also recently played Ceddanne Rafaela regularly at second base to accommodate the club’s surplus of outfielders.

“Obviously he’s a good player, a good defender, was still learning at the big league level but we’ve got some capable guys in the minor leagues in case something happens here,” Cora said.

Mayer said he expects to undergo surgery “as soon as possible” and he’s hopeful to recover quickly enough to enjoy a fairly normal offseason.

“That’s definitely the goal,” Mayer said. “That’s what I’m going to be working towards, but I should be full go by the middle of the offseason.”
