Jason Kubel (hamstring) hopes to return to the Diamondbacks' lineup Tuesday. Kubel hasn't started since leaving last Friday's game with hamstring tightness. "I'm feeling better," Kubel said. "Each day is better and I'm able to get looser easier." Manager Kirk Gibson was a little less optimistic, saying that while the team didn't plan on putting Kubel on the DL, it would have to be considered if he's not ready to play in a couple days.
