Scouting Report
Updated May 19, 2026
Marcelo Mayer, 23-year-old Red Sox infielder, has expressed willingness to move from second base to shortstop following Trevor Story's sports hernia injury. Mayer was drafted 4th overall in 2021 and was a top-15 prospect for four consecutive seasons, playing 269 of 315 minor league games at shortstop. Currently batting .223/.278/.359 in his MLB career. Manager Chad Tracy is open to the position switch if Story requires extended time off, though prefers to keep Mayer at second if Story's absence is brief. Mayer has only played 84 innings at second base in the minors and is still adjusting to the position. He remains under team control for five more seasons.
