New York Yankees: Andy Pettitte Retires After 16 Big-League Seasons

The Core Four is officially no more.

After an entire offseason of 'will he or won’t he retire' talk, five-time World Series champion and 16-year veteran Andy Pettitte will retire, according to Michael Kay of the YES Network.

Without Pettitte, the Yankees have just three pitchers who are definitely in the rotation in CC Sabathia, Phil Hughes, and A.J. Burnett. Sergio Mitre, Ivan Nova, Bartolo Colon, Freddy Garcia, and a few other prospects will battle for the final two rotation spots.
