The day after leaving camp with the flu, C.C. Sabathia returned in a big way, impressing many fans as he pitched batting practice. Derek Jeter caught the injury bug from C.C., with a sore hamstring.
"It's no big deal," Jeter said. "I did everything but run. I'm sure tomorrow you'll see me running. It's really not an issue. If I had a game today, I would have played." - MLB.com
From personal experience, I can tell you that hamstring injuries develop slowly and can turn into major distractions. Drinking water and stretching help treat hamstring issues.
