OAKLAND — The wait is over.
Top prospect Trevor May is set to make his Major League debut for the Twins on Saturday against the A’s. The right-hander will be recalled from Triple-A Rochester to make his first big league start, and a corresponding roster move will come after Friday’s game.
May, ranked as the club’s No. 8 prospect by MLB.com, posted a 2.93 ERA in 17 starts with Rochester. He struck out 91, walked 37 and allowed four homers in 95 1/3 innings. May’s 2.93 ERA ranked fourth in the International League.
May had a chance to make his debut earlier this season, but missed nearly a month with a right calf strain sustained in late June. The injury also kept him from participating in the Sirius/XM Futures Game at Target Field on July 13.
May, along with fellow top prospect Alex Meyer, helped anchor the rotation at Rochester and cut down on his walk rate, which had plagued him in the past.
He’s always had a power arm — he’s struck out 10.5 batters per nine innings throughout his seven seasons in the Minors — but has suffered from control issues. But he’s cut his walk rate in three straight seasons, going from 4.7 walks per nine innings in ’12 to 4.0 last year and 3.5 this season.
May, 24, was originally acquired by the Twins before the ’13 season in the trade that sent Ben Revere to the Phillies. May, who will wear No. 65, was already on the 40-man roster.
