"He's been working hard and we've been talking about it really since I retired," Pettitte said. "I think last year, he started seeing a lot of success and started to make that adjustment into the kind of pitcher that he's going to need to be moving forward. When you have the stuff that he had and was a power pitcher like he was, throwing in the mid to upper 90's, it was a big adjustment for him to almost learn how to pitch again."
"To see the youth, it's exciting," said Pettitte, a Yankees' guest spring training coach. "It's a good shot in the arm for the organization. It will be interesting to see how it all comes along and progress. Hopefully a handful of these guys will be the core group of guys over the next 10 or 15 years in this organization. That would be special to see."
