I think if someone gets on base ahead of the pitcher's spot, Pena bats. But it's hard to hit a 2 run homer with no one on. If he can't tie the game with one swing, it's probably better to let him have today and tomorrow to fully heal the thumb. True, though it highlights how it's a bad idea to have both Johnson and Baker on the bench since neither can hit righties worth a damn. That basically meant that Barney was the only other option if they wanted to save Pena (yeah, there's Hill, but the backup catcher isn't usually going to be used that soon).
