Triston Casas: Everything you need to know

Red Sox interim manager Chad Tracy told reporters Wednesday that Casas (abdomen/knee) is close to being cleared to swing a bat, Christopher Smith of MassLive.com reports. "Obviously the knee's OK. We're just still doing rotational stuff for the side and I think [Casas is] getting closer to maybe starting some light swinging progression," Tracy relayed before Boston's game against Atlanta on Wednesday. Casas underwent surgery in May 2025 to repair a ruptured patellar tendon in his left knee and suffered a setback in his recovery program in the form of an intercostal strain on his left side in early April. The Red Sox should have a better sense of when Casas would be ready to embark on a rehab assignment once he progresses to additional baseball activities, such as live batting practice.

The Red Sox transferred Casas (abdomen/knee) from the 10-day injured list to the 60-day IL on Wednesday. Casas' move to the 60-day IL frees up a spot on the 40-man roster for left-hander Eduardo Rivera, who was called up from Triple-A Worcester. The Red Sox placed Casas on the 10-day IL coming out of spring training while he was completing his recovery from knee surgery, and though his rehab from that injury has gone according to plan, the first baseman has since been shut down from activity after suffering a left abdominal strain earlier this month. Casas is without a clear timeline for a return, but Wednesday's transaction ensures that he'll be on the shelf through at least the final week of May.

Casas (knee) was diagnosed with an abdominal strain Tuesday, Tim Healey of The Boston Globe reports. 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.
