August 21, 2025 1:19 PM : The Red Sox announced that Mayer underwent a successful right wrist arthroscopy Wednesday, Lauren Campbell of MassLive.com reports.
Analysis: 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.
