Pettitte Coming Back For One More?

This is nothing definitive, but Jon Heyman recently posted this on his Twitter account:

nothing definite yet, but andy pettitte apparently told #yankees teammates he'd like to come back for 1 more year.

I think resigning Pettitte, like it was last offseason, is very important. With the question marks hovering around the number 4 and 5 starter spots, the Yankees need to have their top three set, and bringing Andy back would obviously do that.
