Manager Joe Girardi had said that he expected Pettitte to pitch on Monday night for Double-A Trenton, but the game against the Portland Sea Dogs in Portland, Maine, is expected to start with temperatures in the 40s.
"He pitched in some pretty raw conditions [on Wednesday for Trenton] as well," Girardi said before the decision. "Because of that, you might change where he throws. ... Basically, he feels good, though. That's the good thing -- he's bouncing back really well."
Pettitte, 39, is expected to throw 90-95 pitches in his next start. After the upcoming outing, Girardi would not rule out that Pettitte could be promoted to the big leagues, but also said that it is possible Pettitte would start again at Double-A or Triple-A. Girardi said it is not imperative that Pettitte sees Triple-A hitters before jumping to the big leagues.
"I could see how people think that higher competition is going to be a better gauge, but I think we all pretty much have an idea of what Andy needs to do and what his stuff looks like after so many years," Girardi said.
Girardi also said that Roger Clemens' ongoing federal perjury trial has not factored into the Yankees' discussions of when they would promote Pettitte to the Major Leagues. Girardi said that the team could have Pettitte at the big league level even if his anticipated commitments in Washington, D.C., are not complete.
"If that's what you have to do, that's what you have to do," Girardi said. "Andy is pretty good at blocking things out. He has had other things that he has had to deal with in his life. ... I think that wouldn't be a distraction, really. It might keep him from being with us as much as he should be, but I think he'll be able to block it out."
