Drey Jameson has been diagnosed with a UCL sprain in his right elbow and has elected to try to rehab the injury rather than undergo Tommy John surgery.
There isn’t a great track record of pitchers (besides Masahiro Tanaka) attempting to go the rest and rehab route with a UCL sprain, but Jameson will attempt to avoid surgery in an effort to get back on the mound much faster. There is no timetable for his return, but he’s unlikely to pitch again until 2024, even in a best-case scenario.
