Manager Davey Johnson felt Zimmermann had problems locating his pitches.
"I thought his stuff was really good. He didn't locate as good as I've seen him in the past. ... Sometimes, he gets too much of the plate." Johnson said. "I really liked his arm speed, his velocity. His location wasn't quite there. I like what I saw the second time out. ... He was around the plate, just didn't have his great command."
