It's really impossible to separate these three, because it was a result of the solid bullpen that the Yankees were able to prevail in the playoffs.

All three were incredibly clutch in the playoffs. Each recorded at least one World Series victory, and Stanton had two in the Subway Series.

A good bullpen is crucial in deep playoff runs, and the Yankees had a great middle relief system.
