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.

BOSTON — Red Sox rookie Marcelo Mayer will undergo season-ending surgery on his sprained right wrist. The recovery is expected to be three months and so he should be ready for spring training 2026, manager Alex Cora said. The 22-year-old infielder received an anti-inflammation injection Aug. 2, but it didn’t work the way the Red Sox had hoped.
