Mayers was recalled from Triple-A Memphis on Tuesday.
EDGE Analysis
Mayers was solid as a starter for the Redbirds this season, posting a 3.73 ERA and 1.32 WHIP over 16 starts, so he'll get another shot at the big league level now that the rosters have expanded. The right-hander's major league debut this summer was a sour one, as he coughed up nine earned runs over an inning and one-third, but he'll look to improve upon that as he enters the St. Louis bullpen for the stretch run.
