Nationals place Scherzer on 10-day IL with groin inflammation
The move is retroactive to June 12, which means he's eligible to return in one week.
Scherzer exited his outing last Friday after one batter and reportedly cut a bullpen session short Monday. The veteran hurler was scheduled to start against the Pittsburgh Pirates on Wednesday.
"I would injure this worse," Sherzer said of potentially making his next scheduled start, according to MLB.com's Jessica Camerato. "That's the risk you're taking trying to pitch through this. This is just something you can't pitch through. I've pitched through a lot of other things, found a way to do a lot of other stuff. But this one you just can't get around."
The 36-year-old owns a 5-4 record with a 2.21 ERA and 3.05 FIP in 13 starts for the Nationals this season, including 104 strikeouts in 77 1/3 innings.
Washington selected the contract of right-hander Justin Miller and designated fellow righty Rogelio Armenteros for assignment in corresponding moves.
