August 2, 2025 1:51 PM : Mayer received an injection in his right wrist Saturday, Christopher Smith of MassLive.com reports.
Analysis: Mayer will be shut down from all activities for three days following his injection. Once they see how the 22-year-old responds to his treatment, the Red Sox will begin to plan out his next steps, which will likely involve him heading out on a minor-league rehab assignment at some point.
