Overview
- Mayer returned to San Francisco after a flare-up of right-foot soreness and will not join the Giants for their Boston series while he takes the weekend off for medical reassessment.
- The club's medical report ties the foot problem to a bone bruise from fouling a ball in June and notes Mayer is also coming off a left-forearm stress reaction.
- He had recently completed a four-game rehab stint with Triple-A Sacramento in which he went 6-for-17 with one home run, positioning him to potentially debut for San Francisco.
- Mayer was traded from the Red Sox to the Giants on Aug. 3 for left-hander Erik Miller, a move coverage said was driven by Boston's need for more immediate bullpen help.
- Mayer's repeated injuries — including right-wrist surgery, a 2024 lumbar strain, and 2023 shoulder inflammation — have limited his availability and leave both his long-term role and the timing of any big-league return unclear.
