August 17, 2025 11:14 AM : Mayer will require season-ending surgery on his sprained right wrist, Ian Browne of MLB.com reports.
Analysis: 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.
