With Zimmermann going for his 12th straight consecutive quality start, the Nationals need another great performance from him. They played a doubleheader Saturday and Jason Marquis recorded four outs yesterday, so their bullpen is a bit worn down. Zimmermann has allowed two or fewer earned runs in eight straight starts.

The Nationals will try to get their bats going against Casey Coleman, who was called up from Class AAA after Ryan Dempster was scratched. As always, talk about the game right here.
