When Yankees fan favorite Andy Pettitte announced this spring that retirement didn't quite suit him as well as he thought it might, there were a variety of opinions on how he would fare after sitting out a whole year. Would he be vintage Andy, just a decent No. 4 or 5 starter, or would he not even make it out of his extended Spring Training?
Turns out he's the same old Pettitte that Yankees fans know and love, perhaps even better. There's almost no doubt that he is the Yankees' second-best starter, and really he's even pitched better than staff ace CC Sabathia thus far. Without Pettitte, the Yankees are probably still in third or fourth place, not fighting for first with the Rays and Orioles.
So, if Pettitte still had this kind of performance in him, you have to wonder what other retired players could still get the job done if they were to attempt a comeback. I'm sure the argument could be made for a lot of different former players, especially those who retired prior to this season, but for this list I'm going to exclude those newly-retired players and focus on players who have already spent at least a full year away from the game.
