The Arizona Diamondbacks have placed reliever Justin Martinez on the 15-day injured list due to right shoulder inflammation, following a noticeable decline in his velocity during a recent outing against the New York Mets. Martinez, who failed to record an out, allowed a home run and subsequent walks before Ryan Thompson secured the final outs in the Diamondbacks' victory. In a bid to bolster their bullpen, Arizona has recalled left-handed pitcher José Castillo from Triple-A Reno, while A.J. Puk has been shifted to the 60-day injured list due to left elbow inflammation.

Manager Torey Lovullo acknowledged Martinez's struggles and the necessity for a medical evaluation, emphasizing the importance of ensuring he returns to full strength. With Martinez and Puk, who have collectively contributed to most of the team's saves this season, sidelined, Lovullo expresses confidence in the remaining pitchers to maintain performance while they recover.
