I think if Roger pitches well, and the Yankees are no more than two runs behind, he'll go to the 6th. Then David Wells will come in for one or two innings, followed by Mo for two or one inning (depending on how Wells does). If Roger pitches poorly, he'll be yanked early for Wells in multi-inning relief, followed by Mussina as necessary, and Rivera as necessary. I don't think Joe trusts the other middle relievers, and I think he probably got inspiration from Jack McKeon using three starters last night.
I think the key moment of the game will be Wakefield's first batter. If the batter gets a hit, that will inspire the Yankees. If the batter makes an out, it will deflate the Yankees.
But what do I know? Probably no more or less than Tim McCarver, and he PLAYED the game.
