The Red Sox entered the 2025 season with big expectations after adding Garrett Crochet and Alex Bregman to a team that already had Kristian Campbell, Roman Anthony, and Marcelo Mayer all knocking on the door. So far, things have not gone quite as smoothly as fans in Boston were surely hoping. While the club is just two games back in the AL East, that’s with a lackluster 18-18 record thanks in part to spotty health in the rotation behind Crochet. The injury bug has now moved onto the lineup as Triston Casas has undergone season-ending surgery on his knee.
The 25-year-old was expected to be a major piece of the club’s lineup this year, but his campaign is now over before it ever really got going. Casas’s 112 plate appearances this year were subpar, as he hit just .182/.277/.303 across 29 games before going down with injury. Those struggles were mostly fueled by a low .217 BABIP that was sure to rebound given time, however, and there was little reason to think Casas wouldn’t eventually experience enough positive regression and finish the year in that range of a 125 wRC+, which was his career mark entering 2025. Now, of course, he won’t get that opportunity.
Without Casas locking down first base, the Red Sox don’t have many obvious solutions they can rely on to take up the lion’s share of playing time at the position. Romy Gonzalez was off to a hot start (133 wRC+) to open the year in a part-time role, but his .421 BABIP is completely unsustainable and he’s never hit at an even league average level before in his career. Gonzalez is currently slated to share time with Abraham Toro at first base in the short-term, but the switch-hitter has a similarly lackluster career 81 wRC+ while playing mostly in part-time capacities around the AL West over the years. Depth options at the minor league level are similarly uninspiring. Vaughn Grissom was a top prospect in the not-too-distant past but has yet to establish himself at the big league level. Blake Sabol has at least a little experience at first base, but didn’t hit at all in a brief call-up earlier this year.
None of those options appear likely to provide even average production at first base this year for the Red Sox. That could lead the club to look for external additions, but those options may not be substantially better than their current internal group. After all, teams are typically reluctant to swing significant trades this far from the trade deadline, so external additions would likely be limited to non-roster players in other organizations like Mike Ford, Dominic Smith, or Jon Singleton unless they can convince a player like Anthony Rizzo to resume his playing career at this late point in the calendar. Any of those options could make sense as a lefty complement to Gonzalez, and Smith in particular was used as a stopgap by the Red Sox just last year with some success.
Perhaps they could even pry an ancillary 40-man player away without a clear path to playing time away from another organization. Jake Bauers (Brewers) and former Red Sox Justin Turner (Cubs) are both playing in bench roles in the NL Central. Boston’s former chief baseball officer Chaim Bloom now works for the Cardinals, who have Luken Baker on the roster but without much playing time to offer. Juan Yepez is on the Nationals’ 40-man roster but currently playing the minors. Any of those external options could likely be more productive than the club’s internal group of first basemen, but going outside of the organization would require working out a trade with another club who may not be inclined to sacrifice their own depth, particularly in the case of players already on the 40-man roster, and they’re hardly impact options themselves for a team that sorely needs a boost.
One way to replace Casas with a player who can offer a more impactful ceiling would be to move some of the club’s existing talent to first base. Rafael Devers got bumped off third base by the Bregman signing and is currently the everyday DH in Boston. Perhaps he could be shifted to first base, opening up DH for either Anthony or Mayer to make the jump to the big leagues. Another option would be to get Anthony or Mayer regular reps at first in the coming days ahead of a promotion in the near future. Perhaps even Masataka Yoshida, who has been sidelined this year after shoulder surgery hampered his ability to make throws in the outfield, could handle first base and make a quicker return from the injured list.
Any of those players would be a fairly definitive offensive upgrade over either the club’s internal options already familiar with the position or any realistic external additions at this point in the calendar. The problem with that plan, however, is that none of those players have ever played first base as a professional. While the position is fairly low on the defensive spectrum, asking a defensively-limited player like Devers to pick up an entirely new position on the fly seems risky, as would be the case for asking either Mayer or Anthony to balance learning a new position with the adjustments and struggles that can often come with a young player’s first call-up to the majors.
That’s why, as noted by MassLive’s Chris Cotillo over the weekend, Red Sox brass have indicated that they don’t intend to move anyone to first base on the fly. That, of course, could change. The general expectation when the Red Sox signed Bregman was that he would play second base and Devers would remain at third, and that changed fairly quickly after Spring Training began. It’s not out of the realm of possibility that the club finds itself unsatisfied with the options at its disposal and eventually begins having one of the club’s other players taking grounders at first.
How do MLBTR readers expect Boston to address the vacancy at first base? Will they stick with their current group of options, find someone from outside the organization, or move one of their own players to first? Have your say in the poll below:
