"[Manager] Davey [Johnson] is just being cautious with the hamstring and that's fine with me," Werth said. "It's not injured. If it gets much worse, it could be a situation where I could be out for a significant amount of time. It's just tight, if we get to loosen up, it will be all right. There is no strain or significant injury in there. It just needs to loosen up. Whenever that happens, I'll be good to go."
Werth hurt the hamstring and his ankle Monday against the Braves. He played Thursday, but was taken out after the fourth inning.
