Marcelo Mayer, the fourth overall pick in the 2021 Draft, is performing strongly in Boston Red Sox spring training, positioning himself for an Opening Day role at second base. Manager Alex Cora notes that Mayer has been checking all the necessary boxes, though no final decision has been made with one week left before camp breaks. The infielder has shown smooth transition to his new position and solid hitting stats.
In Fort Myers, Florida, Red Sox manager Alex Cora indicated nearly a month ago that the baton is being passed to Marcelo Mayer for the Opening Day second baseman spot on March 26 in Cincinnati. Mayer, a natural shortstop who played third base during his abbreviated Major League debut season in 2025, has transitioned smoothly to second base, building chemistry with veteran shortstop Trevor Story. Mayer explained, “Up the middle, you got to understand your partner... We’re getting a really good understanding of each other. ” At the plate, the left-handed hitter has posted a .250/.400/.375 slash line, demonstrating solid contact. His surgically repaired right wrist appears fully healthy, addressing a key concern. Cora praised, “He’s playing well. He's playing really well... he’s been checking all the boxes.” Mayer missed a game on Sunday due to right knee soreness from adapting to the new position but returned quickly, feeling good afterward. On his chances, Mayer said, “I feel like I've done a really good job... hopefully that's in Cincinnati.” He maintains a good relationship with Cora but focuses on playing hard, regardless of the outcome. Mayer hopes to join best friend and housemate Roman Anthony, who is set for his first Opening Day, avoiding a return to Triple-A.
