The Brewers placed Peralta (shoulder) on the 10-day injured list Thursday.
Peralta was pulled in the third inning of his start during Wednesday's win over the Cardinals after experiencing shoulder inflammation, but Brewers manager Craig Counsell suggested after the contest that the right-hander's removal was mostly precautionary in nature. Though the Brewers are still classifying Peralta's shoulder injury as inflammation, the team will err on the side of caution and deactivate him for at least one turn through the rotation. Given that Milwaukee was looking to manage Peralta's workload down the stretch anyway since he's pitched nearly 100 more innings than he did in 2020, his move to the IL isn't necessarily a major red flag. Assuming Peralta is cleared to resume throwing in the next few days, he should be in line for a minimum-length stay on the IL, or close to it.
