Wilson was a mid-March cut from Spring Training with specific developmental instructions he apparently is following. When he was optioned, general manager Neal Huntington said Wilson needed to "refine his mechanics and become more consistent."
He was consistent enough on Sunday to hold Durham hitless for 7 1/3 innings. Jose (Jumbo) Diaz and Major League veteran lefty Doug Slaten finished up the Indians' first no-hitter since Ian Snell's on May 15, 2005, over Norfolk.
"He's still trying to establish himself, work on consistency and in-game adjustments," said Pirates manager Clint Hurdle, who had called Indianapolis pitching coach Tom Filer earlier in the day to offer his congratulations.
Wilson was pulled after 107 pitches because he had pitched into the eighth inning for only the second time in 78 Minor League starts. However, with Huntington always on the lookout for a matchup lefty, he may at first reach the Pirates as a reliever.
"Love the velocity, the arm strength and the power," Huntington said of the 6-foot-2, 220-pound lefty who was the club's fifth-round choice in the 2008 First-Year Player Draft.
Wilson is not the Bucs' only pitching prospect reigning as pitcher of the week in his league. Jameson Taillon, the Pirates' top prospect and No. 8 overall prospect according to MLB.com, got the honors in the Florida State League after running his current scoreless streak to 11 innings with five shutout frames in Sunday's start.
