July 2, 2025 2:23 PM : Jameson underwent an MRI on his right elbow Tuesday after experiencing renewed tightness coming out of his rehab appearance in the rookie-level Arizona Complex League last Friday, Nick Piecoro of The Arizona Republic reports.
Analysis: Jameson landed on Triple-A Reno's 7-day injured list May 20 due to inflammation in his right elbow, which he previously had surgically repaired in September 2023. After a month of rest and rehab, Jameson was cleared to resumed pitching in games in the ACL last week, but he made just two appearances before suffering a setback. The Diamondbacks haven't revealed the findings of Jameson's recent MRI, but he'll presumably be out of action through at least the All-Star break.
