Diamondbacks Place Eduardo Rodríguez On IL With Shoulder Inflammation

Arizona Diamondbacks left-handed pitcher Eduardo Rodriguez has been placed on the 15-day injured list due to left shoulder inflammation after struggling with a 7.05 ERA and a 1-3 record over nine starts in the 2025 season. Rodriguez's performance has been hampered by his shoulder injury, as he has given up four or more earned runs in four of his last five outings, leading the team to shut him down for further tests and imaging to determine a rehab program. Meanwhile, the Diamondbacks have called up right-handed relievers Christian Montes De Oca, who will make his MLB debut, and Scott McGough from Triple-A Reno, while optioning lefty reliever Joe Mantiply to Triple-A. Ryne Nelson is considered the most likely candidate to fill Rodriguez's spot in the rotation. The team acknowledges that Rodriguez has yet to return to his pre-injury form since signing a four-year, $80 million deal, and they are working to address the command and effectiveness issues linked to his fastball. These roster moves aim to bolster the bullpen and rotation as Rodriguez recovers.
