Diamondbacks Place Justin Martinez, A.J. Puk on Injured List

The Arizona Diamondbacks have placed reliever Justin Martinez on the 15-day injured list due to right shoulder inflammation after a significant and unusual drop in his pitching velocity, despite Martinez insisting he felt fine. He will undergo an MRI to determine the severity of the injury, while left-hander Jose Castillo has been called up from Triple-A Reno to take his roster spot. Additionally, lefty A.J. Puk has been transferred to the 60-day injured list, sidelining another key bullpen arm until at least mid-to-late June. Martinez and Puk were the team's top relief pitchers, and their absences leave the Diamondbacks without clear options for the closer role, with manager Torey Lovullo indicating the team may now rely on a mix of relievers. The injuries come as a blow to a bullpen that was already considered thin, with the team having made only modest offseason additions. The Diamondbacks will provide further updates on Martinez’s condition pending results of his MRI.
