The St. Louis Cardinals announced this afternoon that they have activated right-handed pitcher Miles Mikolas from the 60-day Injured List, and he will draw the start tonight in the team’s series opener against Pittsburgh.
The Cardinals also announced that right-handed reliever Ryan Helsley (right elbow stress reaction) has been placed on the 10-day injured List, retroactive to August 17.  In addition, Memphis (AAA) left-handed pitcher Brandon Waddell has been placed on the COVID-19 Injured List.
Mikolas, who completed a five-game injury rehabilitation assignment with a start last Saturday (Aug. 14), is making just his second start of the 2021 campaign for the Cardinals tonight.  His lone start for the Cardinals this season came on May 22 when he departed after 4.0 innings with a right forearm injury that caused him to miss the past 75 games.
Helsley, who worked 1.1 innings in relief last Saturday in Kansas City, has posted a 6-4 mark with a 4.56 ERA in 51 games while stranding a team-best 27 of 31 inherited runners.
Waddell appeared in four games for the Cardinals after coming over from Baltimore in June. He has logged five games for Memphis, last appearing on June 26.
