The Yankees have asked Joba Chamberlain to be more aggressive in the strike zone. "I don't think Joba goes out there not trying to be aggressive," manager Joe Girardi said of the right-hander, who has struggled with high pitch counts early in games this season. "We talked about it and some times pitchers get out of whack and it's hard to throw strikes," the manager added. "It's something we will continue to talk to him about."
