Diamondbacks Place A.J. Puk On 15-Day IL

The Arizona Diamondbacks have placed closer A.J. Puk on the 15-day injured list due to left elbow inflammation, interrupting a strong start to his season in which he posted a 3.38 ERA and converted all four of his save opportunities. Puk’s injury is of particular concern given his history, which includes Tommy John surgery, though there is currently no indication the issue is more serious than inflammation. In his absence, the Diamondbacks made several roster moves, including optioning Bryce Jarvis and Joe Mantiply to Triple-A and calling up Drey Jameson, while also selecting the contracts of Juan Morillo and J.P. Feyereisen. Puk’s performance had established him as the lead option in the team’s closer committee, ahead of Justin Martinez, who has converted the other two saves for Arizona this season. The shake-up follows a bullpen collapse in a recent loss to the Cubs, highlighting ongoing struggles among other relievers. The Diamondbacks hope Puk’s stay on the injured list will be brief, depending on how his elbow responds to treatment.
