The Boston Red Sox have implemented several changes to their pitching roster during the 2026 season.

In early August, the team promoted left-hander Raymond Burgos from Triple-A Worcester and released left-handed reliever Joe La Sorsa. These moves occurred while the team held a seven-game winning streak and maintained a bullpen ERA of 2.90.

By early September, following a 9-6 loss to the Seattle Mariners, the Red Sox again adjusted their staff by recalling Raymond Burgos and optioning right-hander Jedixson Paez to Triple-A Worcester after Paez allowed eight runs in a recent start. 

On September 2, the Red Sox lost their series against the Mariners with an 8-3 defeat. This loss underscored significant pitching struggles, as the staff has allowed eight or more runs in five consecutive games, a feat that has occurred only four times in franchise history. 

Compounding these pitching issues are several player injuries. Interim manager Chad Tracy described the removal of Ceddanne Rafaela due to quad tightness as precautionary. Additionally, the team has been managing a lingering elbow issue for catcher Adley Rutschman, alongside absences related to Garrett Crochet and Willson Contreras. Despite these challenges, the Red Sox maintain a lead in the American League wild-card standings.

In a recent development, Adley Rutschman made a “triumphant return to Baltimore” as a member of the Red Sox, hitting two home runs to lead Boston to a 6-5 victory over his former team, the Orioles. This performance helped end a slump for Rutschman as he adjusts to his new role following his trade from Baltimore.
