EDGE Analysis

In a corresponding move, the Cardinals placed Carlos Martinez on the 10-day disabled list due to a right lat strain. Mayers has shuffled back and forth from the big leagues to Memphis over opening months of this season, posting 1.86 ERA and 1.34 WHIP in 9.2 innings with St. Louis. He will serve out of a middle-relief role for manager Mike Matheny.
