Rays center fielder B.J. Upton is familiar with shoulder injuries. He had surgery to repair a torn labrum in his left shoulder after the 2008 season. Upton is dealing with a right shoulder strain that forced him to leave Monday night's game, but he's confident it's not serious. "This is a little bit different," he said. "I'm just glad it's not in the back of my shoulder. I don't think it will be anything too serious. It's more muscle." Upton was injured reaching for Delmon Young's eighth-inning drive on Monday night. "I think I just kind of overextended my right arm, the muscle just kind of went numb, and it started to hurt a little bit," Upton said.
