For a while now Minnesotans have been wondering why the Twins haven’t called up 24-year-old pitching prospects Trevor May and Alex Meyer yet. Meyer remains at Triple-A, but Seth Stohs of Twins Daily reports that the Twins will call up May to debut tomorrow against the A’s.

May was acquired from the Phillies in the Ben Revere trade two offseasons ago and repeated Double-A last season before taking a big step forward at Triple-A this year. The hard-throwing right-hander has a 2.93 ERA and 91/37 K/BB ratio in 95 innings, getting his walk rate below 4.0 for the first time in his career.
