Yankee fans, in case you guys haven't noticed, like it when you come up big in the post-season. That's why players like O'Neill, Tino, Jeter, Bernie, Jeter, Pettitte are loved. Hell, Brosius still can't pay for a drink in New York. Bucky Dent is still the 3rd most famous shortstop in Yankee history, after Jeter and Rizzuto. All because of one swing.
Arod hasn't done it in the post-season. Until he does, he'll get booed. It isn't fair, it isn't right, but that's the way it goes here.
I may be looking at winning the lottery first, but if Arod hits a series winning homer against Papelbon, trust me...they won't boo him again for a very long time.
