Boston Red Sox manager Alex Cora has revealed that top prospect Marcelo Mayer will need to prove himself offensively during spring training in order to earn a spot on the Opening Day roster. Mayer made his MLB debut in 2025 but struggled at the plate, batting just .228 with a .272 on-base percentage. With the Red Sox trading for third baseman Caleb Durbin, Mayer is now competing for the starting second base job, though Cora indicated the 23-year-old infielder is not guaranteed a roster spot to start the season.

Why it matters

Mayer is considered one of the top young talents in baseball, so his development is crucial for the Red Sox's future. Cora's comments suggest the team wants to see more consistency from Mayer at the plate before handing him an everyday role, which could impact Boston's lineup and infield defense to start the 2026 season.

The details

Mayer made his MLB debut in 2025, playing in 44 games for the Red Sox. He struggled offensively, batting .228 with a .272 on-base percentage, 4 home runs, and 10 RBIs. With the Red Sox trading for third baseman Caleb Durbin, Mayer is now competing for the starting second base job, but Cora indicated he needs to show improvement at the plate this spring to earn a spot on the Opening Day roster.

  • Mayer made his major league debut in 2025.
  • The Red Sox traded for third baseman Caleb Durbin this offseason.
