Red Sox's Marcelo Mayer: Surgery deemed successful
Rotowire
The Red Sox announced that Mayer underwent a successful right wrist arthroscopy Wednesday, Lauren Campbell of MassLive.com reports.
After initially spraining his wrist in late July, Mayer had hoped that a cortisone shot plus extended rest and recovery time would be enough for him to heal up from the injury and return to action before the end of the season, but surgery was ultimately deemed necessary. Mayer has now sustained season-ending injuries in each of the last three years, as his 2023 campaign was cut short by a shoulder injury, and his 2024 season ended prematurely due to lumbar strain. The 22-year-old -- who previously suffered the same wrist injury in 2022 but avoided surgery -- will face a three-month recovery timeline from his procedure, putting him on track to be back to full health ahead of spring training. Mayer will likely need a strong camp to solidify himself as an everyday player for the Red Sox heading into 2026, after he produced a .228/.272/.402 slash line with a 30.1 percent strikeout rate over 136 plate appearances with Boston prior to being shut down with the sprained wrist.

Red Sox's Marcelo Mayer: Requires season-ending surgery
Rotowire
Mayer will require season-ending surgery on his sprained right wrist, Ian Browne of MLB.com reports.
Shortly after being placed on the 10-day injured list July 25, Mayer received an anti-inflammatory shot, but the rookie's wrist didn't respond as well as the Red Sox had hoped. The 22-year-old has opted for a permanent fix for the injury and is expected to face a three-month recovery, per Mac Cerullo of the Boston Herald. Mayer should be back to full health ahead of spring training, when he'll likely have to compete for a starting role after slashing just .228/.272/.402 with four home runs over his first 44 big-league games.

Red Sox's Marcelo Mayer: 2025 return uncertain
Rotowire
Manager Alex Cora said Friday that Mayer (wrist) has begun taking dry swings, but it's unclear if he will return this season, Mac Cerullo of the Boston Herald reports.
Mayer's recovery from right wrist soreness has been slow, even after undergoing an anti-inflammatory injection at the start of August. The 22-year-old began playing catch this week and has now begun swinging a bat. While it didn't initially seem like the injury would threaten to sideline Mayer for the rest of 2025, Cora was non-committal when asked about the rookie's return this season.

Red Sox's Marcelo Mayer: Starting baseball activities
Rotowire
Mayer (wrist) is scheduled to play catch Monday, Christopher Smith of MassLive.com reports.
Mayer has been on the 10-day injured list since July 24 due to a sprained right wrist.

Red Sox's Marcelo Mayer: Still not ready for activities
Rotowire
Mayer has yet to resume baseball activities since landing on the injured list July 25 due to a sprained right wrist, Christopher Smith of MassLive.com reports.
Mayer received an anti-inflammatory injection Aug. 2, but he's taken longer to bounce back from the sprained wrist than anticipated. The Red Sox's plan was to see how he felt after three days and have him begin baseball activities if the injection had the desired effect, but he's taking part in only individual workouts as of Saturday. Surgery is viewed as an option, but Mayer is still attempting to return this season.

The Red Sox are still collecting information about the nature of Mayer's wrist injury, Gabrielle Starr of the Boston Herald reports.

Red Sox's Marcelo Mayer: Exits with wrist injury
Rotowire
Mayer was removed from Wednesday's game against the Phillies due to right wrist discomfort, Chris Cotillo of MassLive.com reports.
Mayer went 0-for-1 with a walk and a run scored before his wrist forced him out of the game in the fifth inning. The severity of his injury is unclear, but a day off for the Red Sox on Thursday will give him extra time to recover and possibly allow him to be ready for Friday's series opener against the Dodgers.

Red Sox's Marcelo Mayer: Contributes to win
Rotowire
Mayer went 1-for-4 with a double and an RBI in Friday's 5-4 win over the Rays.
Mayer had a run-scoring double for the second straight game, both of which helped the Red Sox come back after the Rays had taken a lead. He's set to become the primary second baseman after the team activated third baseman Alex Bregman from the injured list Friday. Mayer, who is batting .225 through 38 games, has hit safely in three straight games, going 4-for-11 with two doubles, two RBI and two runs scored.

Red Sox's Marcelo Mayer: Set to be primary second baseman
Rotowire
Manager Alex Cora said Friday that Mayer will get the majority of the playing time at second base moving forward, Mac Cerullo of the Boston Herald reports.
The 22-year-old's roster spot appeared in question with Alex Bregman (quadriceps) returning from the injured list Friday, but the Red Sox will keep Mayer in the majors and shift him to the middle infield. The rookie has seen most of his playing time thus far at the hot corner, but he has yet to get on track at the plate with a .234/.272/.421 slash line and 29.8 percent strikeout rate through 37 games. Mayer is starting at the keystone and batting seventh Friday versus the Rays.

Red Sox's Marcelo Mayer: Survives roster decision
Rotowire
Mayer will remain on the Red Sox roster after the team optioned David Hamilton to Triple-A Worcester on Thursday to clear a spot for Alex Bregman (quadriceps), Chris Cotillo of MassLive.com reports.
Bregman's return Friday was going to present a roster crunch, but it's Mayer who will stay in the majors. The 22-year-old top prospect will likely occupy the strong side of a platoon at second base with Romy Gonzalez. Mayer had a key run-scoring double Thursday during Boston's three-run seventh inning.

Red Sox's Marcelo Mayer: Back from bereavement leave
Rotowire
The Red Sox reinstated Mayer (personal) from the bereavement list Monday. Mayer will start at third base and bat sixth in the Red Sox's series opener with the Reds.
After being recalled from Triple-A Worcester on Friday when Mayer was deactivated, infielder Nick Sogard will head back to the minors to clear room for Mayer's return to the 26-man active roster. Before stepping away from the team and missing three games while tending to the personal matter, the 22-year-old rookie slashed .208/.262/.429 with four home runs and seven RBI through his first 84 big-league plate appearances. At least until Alex Bregman (quadriceps) returns from the injured list, Mayer is poised to serve as the Red Sox's primary third baseman.

Red Sox's Marcelo Mayer: Called up, debuting Game 2
Rotowire
The Red Sox selected Mayer's contract from Triple-A Worcester, and he will start at third base and bat sixth in the second game of Saturday's doubleheader against the Orioles, Gabrielle Starr of the Boston Herald reports.
Mayer was informed earlier in the day that he was getting called up to the majors to take the spot on the 26-man roster vacated by Alex Bregman (quad), who was placed on the 10-day injured list. Mayer will make his major-league debut in Saturday's nightcap and is expected to be used across multiple positions in the infield. He has an .807 OPS with two steals, nine homers and 43 RBI across 193 plate appearances in Triple-A this season.

Red Sox's Marcelo Mayer: Set to be called up by Boston
Rotowire
Mayer is expected to be called up by the Red Sox on Saturday, Gabrielle Starr of the Boston Herald reports.
Mayer was not included in Triple-A Worcester's lineup against Durham on Saturday and was seen getting congratulations from his teammates in the clubhouse, per Katie Morrison-O'Day of MassLive.com. Mayer has spent most of his time at shortstop in Triple-A this season, though he's played 10 games at second base and four at the hot corner, and that infield versatility should give him a chance at regular playing time with Alex Bregman (quadriceps) facing a stint on the injured list. Per the official Red Sox broadcast, Mayer could be available to make his major-league debut in the second game of Saturday's doubleheader against the Orioles. The 22-year-old prospect is slashing .265/.342/.465 with two steals, 31 runs scored, nine home runs and 43 RBI in 193 plate appearances in Triple-A this season.

Red Sox's Marcelo Mayer: Getting starts at second base
Rotowire
Mayer started at the second base twice in the last three games for Triple-A Worcester.
Mayer has moved around the infield for the WooSox but has mostly defended at shortstop -- he's made seven starts at second, four at third and 39 at short. That he's made two starts in the last three games is noteworthy, because the Red Sox recently began giving Kristian Campbell practice reps at first base. If Campbell adapts to the entirely unfamiliar position, he could serve as the team's primary fill-in for the injured Triston Casas (knee), which would open up second base, potentially for Mayer or David Hamilton.
