Isiah Kiner-Falefa

With some of the Boston Red Sox's depth options at first base banged up, including Triston Casas (knee) and Romy Gonzalez (shoulder), new infielder Isiah Kiner-Falefa has taken reps at the position in spring training, according to Sean McAdam of MassLive.com. Kiner-Falefa's primary positions are second base, shortstop, and third base, but he's played literally every other position on the field in the majors, including catcher. He might not really be needed at first in 2026, depending on the health of Casas and Gonzalez, but getting the experience at first this spring doesn't hurt. The 30-year-old veteran has never hit more than eight home runs in a season in his eight years in the big leagues, and he's unlikely to have much fantasy appeal in 2026 with the BoSox in a utility role. Kiner-Falefa should only be rostered as a player with modest speed and positional versatility in AL-only leagues.
