The Cardinals optioned Mayers to Triple-A Memphis on Monday.
A night after he got shelled by the Dodgers, the Cardinals sent the right-hander back to Triple-A Memphis. The 24-year-old was having a fantastic season between Double-A and Triple-A before getting called up, compiling a 2.62 ERA and 1.21 WHIP with 86 strikeouts in 106.2 innings. Back in Memphis, he'll need to work on his command of the strike zone.
