16 year veteran Andy Pettitte has come out of retirement to sign a 1 year deal worth 2.5 million dollars. Pettitte has won 240 games over his career, and his life time winning percentage is 635. He is well known for his dominance in the post season, where he has risen to occasion and won 21 games. I believe this move is beneficial for players such as Michael Pineda, and Ivan Nova and in September he could help young south paw Manny Buenalos. Pettitte was a member of the core four including Derek Jeter, Mariano Rivera, and Jorge Posada. As a Yankees fan I love the move and hope for the best.
