From Yankees.com:

Mariano Rivera's role in this postseason? He will be Torre's ninth-inning guy, pure and simple.

"Yeah, we're going into to the postseason with Mariano being a ninth-inning pitcher," Torre said. "We feel we have enough support leading up to him to be able to do this." ...

Don't expect Rivera to be called on in the eighth inning as he has in so many instances during October. Don't expect him to turn in the type of three-inning masterpiece that occurred in Game 7 of the 2003 ALCS against the Red Sox.

(I think the article reads too much into Torre's comments, "going into" is like saying "we'd like to."). Anyway, we all know (and Torre knows it, too, of course) that when it's really on the line, that goes out the window.
