May (5-5) took a no-hitter into the sixth inning before allowing a leadoff single to Manatees' shortstop Josh Prince. The Phillies' fourth-round pick in 2008 retired the next three batters in order, putting an end to the right-hander's evening.

The 20-year-old Washington native, a Florida State League All-Star this season, has rebounded from a rocky May. After going 2-2 with a 5.60 ERA and a 1.87 WHIP in five starts, he has gone 2-1 with a 4.19 ERA in June. In his last three starts, he's allowed two runs on six hits, striking out 16, over 16 1/3 innings.

Clearwater reliever Chance Chapman picked up where May left off, fanning two over two perfect innings. Christopher Kissock gave up a hit and struck out one in the ninth to close out the game for the Threshers (36-32), who have won three straight.

May received plenty of help from Clearwater's offense, which pounded out 14 hits. Steve Susdorf was 4-for-5 with a double and an RBI, while catcher Tim Kennelly added three singles and drove in two runs. Former second-round pick Anthony Gose singled and stole his 25th base for the Threshers.
