Boston Red Sox pitcher Patrick Sandoval is facing a potential injury setback due to left bicep tightness experienced after his latest rehab start with Triple-A Worcester. Manager Alex Cora confirmed that Sandoval returned to Boston for evaluation, which is concerning given his history of injuries. Sandoval, who missed the entire 2025 season recovering from Tommy John surgery, had a challenging 2024 season with a 5.08 ERA over 16 starts with the Los Angeles Angels before signing with the Red Sox. In his rehab outings, he allowed no runs in 3 1/3 innings during his first start but struggled in the second, giving up five runs in two innings. Cora noted that the team is monitoring Sandoval closely, but the uncertainty surrounding his condition adds to the Red Sox's injury woes.
