Boston Red Sox first baseman Triston Casas has undergone arthroscopic surgery on his left wrist, the team announced Thursday. This marks the latest setback for the 26-year-old, who has been sidelined since May 2, 2025, after rupturing his left patellar tendon.

Casas missed the remainder of the 2025 season and then experienced an abdominal strain during spring training before the wrist injury surfaced. The Red Sox have not provided a timeline for his return. His injury struggles began in 2024, when he missed 99 games due to torn rib cartilage.

The 6-foot-4 Casas has played in just 92 games since 2023, the year he finished third in American League Rookie of the Year voting. His absence continues to impact the Red Sox lineup.
