Arizona Diamondbacks left-hander Madison Bumgarner was placed on the 10-day injured list Thursday with inflammation in his throwing shoulder.
Bumgarner underwent an MRI on Thursday after leaving Wednesday’s 7-6 loss to the New York Mets early. Bumgarner pitched just two innings in the game — his shortest outing since Aug. 9, 2020 — while allowing five earned runs on eight hits.
Bumgarner said Wednesday that he first started feeling the discomfort two to three weeks ago but didn’t tell the Diamondbacks because he thought his shoulder would start feeling better.
“This is just bad judgment on my part,” he said. “I thought it was going to get better and go away sooner. The last three to four days, it’s gotten worse and affected my pitching.”
Bumgarner is 4-5 this season with a 5.73 ERA in 14 appearances (12 starts).
Right-hander Humberto Castellanos was recalled from Triple-A Reno on Thursday in a corresponding move.
