Cardinals right-hander Michael Wacha has been scratched from Wednesday's start against the Nationals. Tyler Lyons, who was recalled Wednesday, will get the start in place of Wacha.
Cardinals manager Mike Matheny said Wacha is being skipped in an effort to limit his innings, according to USA Today. Wacha is currently at 157 1/3 innings this year, which is about 50 innings more than he pitched all of last season.
