Utility man Mark DeRosa (inset), who was on the disabled list with a left oblique strain, aggravated his injury after Bryce Harper high-fived him after stealing home against the Phillies on May 6. "I don't know if that set back the rehab or not," Nationals manager Davey Johnson said. "But I said, `Why didn't use your [right] hand?' He said it was spur of the moment."DeRosa had not played since April 27 because of his oblique strain; he was hitting .081 (3-for-37) before the injury.
