he's no lock to stay in the rotation if/when Carp comes back. He wouldn't get a full season of innings this year, anyway, so the pen is a nice way to limit that. Given his success in the pen last year, it's not the worst thing in the world for the team assuming Lohse and Westbrook have continued to be good enough at the back end of the rotation. No one really knows what's going to happen with Carp, though.
I think he has gone a long way to securing his spot in the rotation next year, if he doesn't have it virtually locked up now.
The recent chatter about the Cards talking with Oswalt again is interesting on this front, too.
When you are a man, sometimes you wear stretchy pants in your room...is for fun.
