The competition for the Boston Red Sox’s starting second base job saw a change, as one player exited the race while another entered.
The Red Sox optioned five players to the minors, including Vaughn Grissom, who had been vying for the second base role alongside Kristian Campbell and David Hamilton since the start of spring training. Despite logging plenty of innings early in camp, Grissom struggled offensively, managing just a .176 batting average.
The remaining contenders haven’t fared much better at the plate. Campbell, ranked as the team’s No. 2 prospect, is hitting only .158, while Hamilton holds a .239 average.
In response, Red Sox manager Alex Cora has given top star a look at second base over the past two games, including a start. Reports indicate the decision to use veteran star as a backup at second came on short notice, with Mayer learning of his assignment just before the game.
“I try to stay ready for anything, especially since I haven’t locked down a position at this level,” Mayer said. “You’ve got to be flexible and willing to do whatever is needed.”
Boston Red Sox Take Look at Marcelo Mayer Playing Second Base
Mayer, ranked as the Red Sox’s No. 3 prospect, has had a standout spring, posting a .355/.444/1.025 slash line. The fourth overall pick in the 2021 Draft, Mayer has primarily focused on shortstop, but with Trevor Story locked in at that position, the team may be exploring other ways to keep Mayer’s bat in the lineup. Manager Alex Cora said they’re confident Mayer’s defensive skills will translate smoothly to second base.
“He takes pride in his defense and enjoys it, and it comes naturally to him,” Cora said. “So whether it’s second, short, or third, we’re comfortable. He’s a solid defender.”
If Mayer makes the team, he would be the first Red Sox player to debut in the Majors without playing a Triple-A game since Andrew Benintendi in 2016. Mayer batted .307 over 77 games at Double-A before being promoted to Worcester late last season, though a back injury kept him from appearing in any games there.
The 22-year-old said he’s prepared to contribute in any role the Red Sox need.
“Yeah, I believe so,” Mayer said after Wednesday’s spring training game. “But at the end of the day, that’s not up to me. The front office makes those calls. I feel ready, mentally and physically, I’m swinging the bat well — so we’ll see what happens.”

Marcelo Mayer ‘Has a Shot’ at Getting Second Base Spot
The battle for the starting second base job has lacked a clear favorite all spring, though some recent lineup choices have hinted that Campbell might be the leading candidate. Still, manager Alex Cora maintains that the competition remains open.
“This final week will determine our decision,” Cora said.
There are growing signs that Mayer is firmly in the mix.
“Everyone has a chance,” Cora added.
