In a relief role following his signing last June, Wacha appeared at three levels (Gulf Coast League, Florida State League and Texas League) and posted a 0.86 ERA in 11 appearances (two starts) while striking out 40 batters in 21 innings pitched with only four walks. He also appeared in two games during the run to the Texas League championship by Double-A Springfield.
Assuming Michael Blazek pitches for St. Louis first, Wacha will become the eighth rookie pitcher to appear in game action for the Cardinals this season and the 10th pitcher age 25 or younger to do so. The Cardinals have received a Major League-leading 12 wins from rookie pitchers this season.
The Cardinals will announce corresponding player moves affecting both the 25-man and 40-man rosters prior to Wacha's start.
