Boston Red Sox

Sonny Gray

SP

Gray was pulled from Monday's start against the Tigers in the third inning due to a right hamstring injury. He underwent imaging following his exit, and the injury appears severe enough for him to warrant a stint on the IL. Per Cotillo, the Red Sox are expected to recall Tyler Samaniego from Triple-A Worcester ahead of Tuesday's game against the Yankees. However, Payton Tolle could be called up to the majors and replace Gray in Boston's rotation for as long as the latter is sidelined.

Patrick Sandoval

SP

Shortly before he was scheduled to make his third rehab start with Triple-A Worcester on Sunday, Sandoval was pulled off his minor-league assignment and reported to Boston to receive further evaluation after experiencing biceps tightness following his previous outing. Fortunately for Sandoval -- who is working his way back from a June 2024 internal brace surgery on his left elbow -- he appears to have avoided any sort of major setback and could soon be ready to link back up with Worcester to continue his rehab assignment. Even so, the 29-year-old left-hander still isn't expected to be ready to return from the 15-day injured list until at least early May, and the Red Sox may not have a rotation spot available for him once he's activated.

Kutter Crawford

SP

Crawford underwent the MRI late earlier in the week after experiencing soreness in his forearm following his first rehab start at Triple-A Worcester last Saturday. He's still awaiting his doctor's assessment, but the Red Sox should soon have an update regarding Crawford's next steps. Crawford missed the entire 2025 season, initially due to patellar tendon soreness before he developed a wrist problem that he treated with surgery in July.

Justin Slaten

RP

Slaten landed on the 15-day injured list April 8 due to a right oblique strain. He's progressed enough in his recovery to start playing catch and will likely need some turns in a rehab assignment before being cleared to return to major-league action. Slaten appeared in four regular-season games prior to his IL stint, recording two holds while allowing one unearned run on two hits and two walks with five strikeouts over 3.1 innings.

Triston Casas

1B

Casas began the regular season on the injured list to finish up his recovery from patellar tendon surgery but began to have problems with his left side after he resumed a swinging progression. Now that he's been confirmed to be dealing with an abdominal strain, the 26-year-old will be shut down from all activity until he begins to feel better. The Red Sox will then begin to build him up in a similar fashion to spring training, at which point a clearer timeline for his return to play could emerge.
