2026 Fantasy Outlook
Despite enjoying a strong spring training, Mayer opened the season with Triple-A Worcester, in part to get reps all around the infield. He was called up to make his major league debut in late May, playing third base while Alex Bregman was on the injured list. Mayer served as the left-handed part of a platoon, shifting to second base when Bregman returned in early July. He struggled to adapt to major league pitching, fanning at an elevated 30.1 percent clip while walking just 5.9 percent of the time before being sidelined by a wrist injury that ultimately ended his season. Despite these challenges, Mayer remains a significant part of the Red Sox plans, with the ability to play shortstop, second base, and third base. He could break camp as a starter or super-utility player, or even be assigned to Triple-A to demonstrate his readiness after recovering from wrist surgery. Read Past Outlooks
