Span is not sure if he had a setback. He indicated that he would know more by Friday. Since coming off the disabled list on April 19, Span has been a hot hitter, going 13-for-43 (.302) with two home runs and seven RBIs.
"I'm a little sore, but I think I will live," Span said. "[The soreness] is around the surgery site. It's a little sore. I just followed my intuition. I ran out there and stared to feel it in my last at-bat. I tried to go out there and play defense. My intuition just told me I need to go in and cash it in and see if I can get some treatment on it and feel better tomorrow."
