For the first time this spring, the Yankees big league hitters faced live pitching. The first pitcher on the main field was Joba Chamberlain, throwing to a group of Derek Jeter, Robinson Cano, Travis Hafner and Eduardo Nunez. “(Chamberlain) looks like he has the strength,” Joe Girardi said. “I’m not going to get too caught up if the first half of March, even in the third week of March, he’s still throwing 92, 93. As we get closer to the end, I expect to see the power that he has. I think you’ll see it from him, but sometimes arm strength takes some time to develop in spring training for these power guys.”
