Andy Pettitte was huge for the Yankees last year becoming a dominant pitcher later and later into the season. He posted a 14-8 record with a 4.16 ERA in the regular season. Pettitte was dominant in the postseason for New York also. He was 4-0 in 5 postseason starts. He clinched the ALDS, ALCS, and the World Series against familiar-foe Pedro Martinez in New York.
This move is great. The first three spots in the starting rotation will be a bit easier to fill out now.
