Marcelo Mayer fielded grounders at second base on Friday.

Mayer entered the season expected to be the Boston Red Sox’s starting third baseman following Alex Bregman’s departure. However, the team acquired Caleb Durbin last week, who took grounders at third base Friday and is projected to be Boston’s opening day third baseman, with Mayer shifting to second base. Mayer slashed .228/.272/.402 in 136 plate appearances as a rookie last year.

Red Sox chief baseball officer Craig Breslow said during the Winter Meetings that Marcelo Mayer underwent a follow-up exam last week.

Per Breslow, everything went "really well" in the follow-up for Mayer. He continues to work his way back from undergoing wrist surgery back in August. He is expected to open next season as the starting third baseman for the Red Sox if they don't bring back Alex Bregman.

Red Sox chief baseball officer Craig Breslow said Monday that Marcelo Mayer’s recovery from right wrist surgery has progressed to the point that he could have been available if the team had advanced further in the postseason, Rob Bradford of WEEI.com reports. Mayer underwent arthroscopic surgery on his right wrist in August but is expected to be fully healthy well before spring training.

Fantasy Impact

Mayer’s recovery puts him on track to compete for a spot on Boston’s Opening Day roster in 2026. The 22-year-old could break camp as a starter at either second or third base, depending on offseason roster moves. His combination of contact skills and developing power keeps him an intriguing stash in keeper and dynasty formats.

Marcelo Mayer has been cleared to resume doing baseball activities.

Fantasy Impact

Mayer began playing catch earlier this week. He also began taking dry swings.

The Red Sox transferred INF Marcelo Mayer from the 10-day to the 60-day injured list.
