Pittsburgh, PA (SportsNetwork.com) - The Pittsburgh Pirates put right-hander Stolmy Pimentel on the 15-day disabled list Saturday with inflammation in his pitching shoulder.
The move is retroactive to Friday, a day after Pimentel surrendered the game- winning home run to Matt Wieters in the 10th inning of Thursday's 6-5 loss to Baltimore in the finale of a doubleheader.
Pimentel, 24, is 2-1 with a 3.18 ERA in six relief appearances this season.
Also Saturday, the Pirates optioned right-hander Brandon Cumpton to Triple-A Indianapolis. They recalled righty Jared Hughes and selected righty Vin Mazzaro, also from Indianapolis.
