MANHATTAN — One of the pillars of the Yankees championship teams in the 1990s is hanging up his pinstripes.
The retirement would mean Pettitte would be the first of the four core Yankees players who joined the team before they began their championship run in 1996.
Pettitte, Derek Jeter, Jorge Posada and Mariano Rivera were part of a new class of Yankees who helped bring New York City four World Series victories between 1996 and 2000.
The left-handed ace won 19 post-season games — the most of any pitcher all-time.
He had a strong season in 2010, going 11-3 with a 3.28 ERA.
Pettitte’s retirement leaves a question mark in the Yankees rotation. The team was unable to land Cliff Lee in the off-season and now have only three experienced starters — CC Sabathia, Phil Hughes and AJ Burnett.
