"When Zim comes to the plate in a situation like that you know he's got a really good chance at it," said Detwiler. "You know, he's got a better chance at it than just about anybody else so you feel really good about it."
Clippard pitched around a one-out walk in the bottom of the eighth, and the Nationals went ahead in the ninth.
