New York Yankees veteran starter Andy Pettitte admitted that his legs are not in shape, pushing back a possible start date for the left-hander.Pettitte told the New York Post that he needs more time to tune up his legs if he wants to progress with his throwing program. He has pitched in only two innings of simulated action so far this offseason.“The last thing I want to do is rush something,” he told the media Saturday. “At this point, it wouldn’t be smart. (The simulated game) was great, but it’s not a real game. It’s still not another team.’’The Yankees signed the 39-year-old pitcher to a minor-league deal this offseason. Pettitte didn’t pitch in 2011 but posted an 11-3 record and a 3.28 ERA in 2010.
