PITTSBURGH -- Casey McGehee had to come out of Sunday's game after incurring a mild left groin strain delivering a two-run single that gave the Pirates a nine-run lead over San Francisco.
Manager Clint Hurdle could not offer an update after the Pirates' 13-2 victory on the prognosis for McGehee who, according to a member of the team's athletic training staff, was still undergoing tests.
McGehee's drive to the deepest corner of PNC Park scored Neil Walker from second base and Andrew McCutchen from first, but McGehee stopped at first, hunched over with hands on knees.
After briefly consulting with an athletic trainer, with Hurdle in tow, McGehee walked off the field and was replaced by pinch-runner Gorkys Hernandez.
McGehee buckled slightly as he ripped Brad Penny's first pitch to left-center and was limping by the time he took a couple of steps out of the batter's box.
