Joba Chamberlain had a rough outing on Thursday against the Phillies. He yielded homers to Chase Utley and Ryan Howard and also walked three and struck out three.

"I think it's going to come with being more consistent with my fastball," Chamberlain said. "I feel good with everything. It's just that I get a little erratic with my fastball. It comes as I continue to get pitches in. There's time."

Girardi said that Chamberlain's velocity (low 90s and hit 95 mph) was not a concern.

"This is pretty much what we saw last year," Girardi said. "As a starter, usually you're not going to have the same velocity as you do one inning coming out of the bullpen. You might get up there, but it's a little bit harder to stay up there. We just continue to build arm strength with him."
