The conversation did not go the way Andy Pettitte had hoped. He told the Yankees’ hierarchy that his back felt better and he was ready to pitch Tuesday against the Arizona Diamondbacks. "And they said, ‘OK, you’re pitching Friday,’ " said Pettitte, trying to hold back his polite frustration. The Yankees again pushed back the 40-year-old left-hander, who will miss the Arizona series. Instead, he will wait three more days and face Toronto. Manager Joe Girardi said Pettitte did not suffer a setback. The Yankees just want to be cautious and not lose him for an extended period. Ivan Nova, CC Sabathia and Phil Hughes will pitch in the Arizona series. "I’m onboard to a certain extent. I just want to pitch," Pettitte said. "I understand it, but I just feel a ton better." Pettitte suffered back spasms Thursday night, pushing back his scheduled Sunday night start.
