Cardinals' Adam Wainwright: Next rehab outing scheduled

Wainwright (groin) will pitch in his third rehab start Sunday with Triple-A Memphis, Katie Woo of The Athletic reports.

Wainwright has made two starts with St. Louis' minor-league affiliates and managed to complete 4.1 innings his last time out. In total, he's managed a 4:1 K:BB while allowing five earned runs across 7.1 frames in those two outings. His target is 90 pitches Sunday, meaning if all goes well he could step into the big-league rotation late next week.
