Mayers was optioned to Triple-A Memphis on Monday, Jennifer Langosch of MLB.com reports.

EDGE Analysis

Mayers finished with a sharp 1.64 ERA and 1.00 WHIP over 11 spring innings, and the 25-year-old likely made an impression on Cardinals brass. That said, with options remaining and a solid veteran bullpen in place in St. Louis, Mayers's chances of making the team out of spring training were slim to none to begin with. If he can carry his strong performance into the regular season, he'll be a top call-up option should the Cardinals need reinforcements.
