Boston Red Sox first baseman Triston Casas has undergone successful surgery to repair a ruptured patellar tendon in his left knee, effectively ending his 2025 season. The injury occurred on May 2 during a game against the Minnesota Twins, when Casas stumbled over first base after an infield single and had to be carted off the field .
The surgical procedure, performed by Dr. Eric Berkson at Massachusetts General Hospital, was completed less than 48 hours after the injury. The team confirmed that the operation went smoothly, with no complications reported . Recovery from such an injury typically requires 6 to 12 months of rehabilitation, making a return this season highly unlikely .
Casas, 25, had been struggling at the plate this season, batting .182 with three home runs and 11 RBIs over 29 games. This marks the second consecutive year he’s faced significant injury setbacks, having played only 63 games in 2024 due to a left rib cage injury .(
In the wake of Casas’ injury, the Red Sox have explored various options to fill the void at first base. Abraham Toro and Romy Gonzalez have been utilized as temporary solutions . The team also approached designated hitter Rafael Devers about a potential position change, but he declined, citing prior assurances that he would remain in the DH role .As the Red Sox navigate the remainder of the season without their starting first baseman, Casas begins the long road to recovery, aiming to return to full strength for the 2026 season.
