Wilson goes back to bullpen


LHP Justin Wilson again is in transition from being a starter to a reliever at Triple-A Indianapolis. “It might give him an opportunity to be more impactful at the major league level,” manager Clint Hurdle said. In 23 starts at Indy, Wilson is 8-5 with a 4.14 ERA and a 1.24 WHIP. When rosters expand Sept. 1, the Pirates will look to give lefty Tony Watson some help. Wilson and Doug Slaten (who today was outrighted to Indy after clearing waivers) figure to get callups.

A fifth-round draft pick in 2008, the 24-year-old Wilson has been a fast-riser in the farm system. He started 73 of his first 74 outings, throwing a curveball, slider, changeup and a fastball that touched 94 mph. As part of the rotation last season at Indy, Wilson’s strikeout-to-walk ratio dipped, and the number of hits and walks he allowed per inning rose. When he was switched to a reliever for nine outings, Wilson’s velocity spiked at 99 mph and his command improved.

»»» SS Brock Holt was promoted to Triple-A Indy. He takes the roster spot of Jeff Larish, who’s on the DL.
