Mayer exited the Red Sox’ game against the Phillies on July 23 in the bottom of the fifth inning with an injury later determined to be to the triangular fibrocartilage complex.

Red Sox rookie infielder Marcelo Mayer has been out since July 23 with a wrist injury and the hope was he would return at some point this season. Sunday, though, Red Sox manager Alex Cora told reporters that isn't going to happen. Mayer will have surgery to repair the right wrist injury, Cora said, and will miss the rest of the 2025 season.
