The St. Louis Cardinals placed right-handed reliever Ryan Helsley on the 10-day injured list Friday with a stress reaction in his right elbow.
Helsley, 27, is 6-4 with one save and a 4.56 ERA in 51 appearances out of the bullpen this season.
The injury designation is retroactive to Tuesday for Helsley, whose spot on the active roster was filled by right-hander Miles Mikolas, 32.
Mikolas (0-0, 2.25 ERA) came off the 60-day injured list to start Friday night’s series opener against the visiting Pittsburgh Pirates. He missed the past 75 games with a right forearm injury.
The Cardinals also announced that Triple-A Memphis left-hander Brandon Waddell was placed on the COVID-19 injured list.
