The Cardinals recalled right-handed pitcher Greg Holland from Class A Palm Beach and optioned right-handed pitcher Mike Mayers to Triple-A Memphis on Monday.
Holland, who was signed to a one-year free-agent contract on March 30, appeared in two games for the Palm Beach Cardinals, totaling 2.0 innings pitched with a scoreless relief appearance on April 5 and a start on April 7 during which he allowed one run on two hits in 1.0 inning.
Holland, 32, pitched for the National League Wild Card-qualifying Colorado Rockies in 2017 after spending his first six Major League seasons with the Kansas City Royals (2010-15).
