Diamondbacks Make Roster Moves Amid Bullpen Injury Crisis

The Arizona Diamondbacks made significant bullpen changes following a 13-11 loss to the Chicago Cubs, highlighted by the placement of left-hander A.J. Puk on the injured list due to elbow inflammation and a pending MRI. To address their depleted bullpen, Arizona recalled right-hander Drey Jameson and selected right-handers J.P. Feyereisen and Juan Morillo from Triple-A Reno, while optioning Joe Mantiply and Bryce Jarvis—both of whom struggled in recent outings—back to Reno. The loss of Puk further exposes the Diamondbacks' lack of left-handed relief depth, an issue compounded by Mantiply's poor performance and declining velocity this season. The reshuffling aims to stabilize the bullpen as the team navigates injuries and inconsistency among relievers. These moves reflect the challenges managers face when bullpen availability is uncertain due to undisclosed injuries. The Diamondbacks hope the promoted pitchers can provide immediate support to a struggling relief corps.
