Kyle McClellan (back) was not able to throw his scheduled bullpen session Sunday. McClellan is still nursing a sore back. "Frustrating," McClellan said. "It's going to take time. It's disappointing games have started and you're not in them. But we've got a lot of time. If it's still an issue in two or three weeks, I'll be concerned." The back ailment isn't a big concern, but it doesn't help McClellan's chances at earning an Opening Day bullpen spot.
