Overall, I'd say you've put together a good team for a 12 team league. Your pitching is obviously your strong suit, between the two big aces up front to go with a few of the more effective closers in the game right now.
My only recommendation would be to move one of your pitchers, such as Zambrano, Kazmir, etc. to try and upgrade at your utility spot. If you want steals, I'd try to get someone like Nyjer Morgan over Juan Pierre. Good luck.
