Right-hander Freddy Peralta was placed on the 15-day disabled list Monday with a right lat strain, while closer Josh Hader was placed on the family medical emergency list.
Peralta was on a roll heading into his eighth start of the season before complaining of shoulder soreness in a start against the Nationals on May 22. A right lateral strain was discovered during an MRI exam on Monday. Tommy John's surgery is not an option at this time.
Craig Counsell on Peralta: "He will be back this season but it's going to be a lengthy absence. We're confident that there's gonna be no kind of, like, after-effects to this thing but it's going to take a while to heal and then build it back up."
After exiting his start on Sunday, Peralta was placed on the 15-day IL on Monday.
Peralta had a breakout year in 2021. In 144 1/3 innings, he was 10-5 with a 2.81 ERA (150 ERA+), 0.97 WHIP, and 195 strikeouts, good for 4.0 WAR. Before going on the IL with shoulder discomfort, he was in line for some Cy Young consideration last season. Peralta currently has 50 strikeouts in 38 2/3 innings with a 2.09 FIP and a 4.42 ERA, including Sunday's start.
In other news, Josh Hader will miss the whole three-game series against San Diego due to his wife's pregnancy, according to manager Craig Counsell.
"Josh's wife has had complications with her pregnancy and they're at a stage where Josh did not feel comfortable leaving,'' Counsell said.
