Joba Chamberlain vows to pitch again this year for the Yankees.

Speaking for the first time since suffering an open dislocation of the subtalar joint in the heel area of the right foot Thursday jumping on a trampoline with his son, Chamberlain said the injury is just the latest hill to climb.

"I am going to continue to work hard to be ahead of schedule or right on schedule,'' said Chamberlain, whose goal to come back from Tommy John surgery was June. "Obviously there are a lot of things that have to happen before that — the mere fact that what we have been told, no broken bones. I don't have to worry about running the bases, so that is another thing that goes along with this. I think there is a great chance of that definitely happening.''
