HOUSTON — Red Sox first baseman Triston Casas has been shut down from hitting because of an intercostal strain on his left side. He has not undergone imaging.
Intercostal muscles are located between the ribs.
Casas began the season on the 10-day injured list as he works his way back from season-ending surgery that he underwent in May 2025 to repair a ruptured left patellar tendon .
Casas previously dealt with a rib injury in 2024. He was limited to 63 games that season after he tore cartilage in his rib cage on a hard swing in Pittsburgh in April 2024.
"Casas has had a setback," manager Alex Cora said before Wednesday's series finale between the Red Sox and Astros at Daikin Park.
"Sore ribs. So they kind of like shut down the hitting thing for a while," Cora added. "It just happened a few days ago. So we have to slow it down. Nothing related to the knee. He's doing well but this happened swinging, so we have to shut him down swinging-wise for I don't know how long."
Casas' rib injury in 2024 was a freak occurrence that doctors likened to a "car crash" within his body .
Casas' ruptured patellar tendon last year then limited him to 29 games.
He finished third for the 2023 AL Rookie of the Year award, posting an .856 OPS while hitting 24 home runs, 21 doubles and two triples in 132 games. His inability to stay healthy since the start of the 2024 season prompted the Red Sox to trade for first baseman Willson Contreras this past offseason .
