PITTSBURGH -- Infielder/outfielder Mark DeRosa, who is on disabled list because of a left oblique strain, suffered a minor setback during Sunday's 9-3 loss to the Phillies, according to manager Davey Johnson.
DeRosa injured his right shoulder while cheering for Bryce Harper, who stole home in the first inning of Sunday's game. It's not known how DeRosa hurt the shoulder.
"I don't know if that set back the rehab or not," Johnson said. "It was a spur-of-the-moment thing," Johnson said.
