Four Internal Red Sox First Base Options After Triston Casas Injury

The Boston Red Sox lost their starting first baseman Triston Casas Friday night to a “significant knee injury” in the second inning against the Minnesota Twins.

The first baseman played just 63 games last year and suffered an early-season injury for the second season in a row. While Boston will not have more details on Saturday, it certainly appears the Red Sox will be without Casas for the foreseeable future this season.

Boston has a special team that, despite early inconsistencies, has the makings of an American League contender. Without Casas, the Red Sox need to act fast to find serviceable production at first base in his absence.

If the Red Sox prefer an in-house option, here are four options that may be considered.

Vaughn Grissom
Grissom lost out on the starting second base competition to Kristian Campbell in spring training. He returned to Triple-A Worcester and caught fire to start the season. Worcester even gave him four games at first base to better prove his versatility.

Grissom currently sits with a .289 batting average with three home runs, 12 RBIs and an .825 OPS as he works for his next Red Sox opportunity.

Romy Gonzalez
Gonzalez has started at first base most of this season against left-handed pitchers and virtually platooned with Casas to start the 2025 campaign. Alex Cora has inserted reps for Gonzalez before and will likely play there the next few days while the Red Sox figure out their sustained plan.

Not Roman Anthony
The Red Sox already said they will not try their top prospect, an outfielder, at first base with the chance to hurt his development.

In the immediate aftermath of the Casas injury, here’s another reminder.

Rafael Devers?
The Red Sox will not use Devers in the field after his move to designated hitter, so this option feels rather unlikely as well. With that said, corner infield position switches aren’t a new concept, and it’s interesting to see if Boston would consider Devers as a short-term solution.
