It was Girardi, last day of 2011. Yanks had 1st clinched, and a 7-0 lead in the bottom of the 8th in Tampa.
Rays were battling the really Red Flops for the Wild Card -- when there was only one. Yankees played just about everyone on their roster except Mariano Rivera that day: 16 position players and 11 pitchers -- the last third who did their best to blow the game.
Girardi could've stopped the bleeding any time he wanted if he brought in Mo, but he just sat there smiling, because even if the Red Sox won, they'd have to play the Rays the next day in a one game playoff... and burn up more arms and legs, and not rest all their end of the year aches and pains.
Of course, when Pap and Crawl Cawful blew it in Baltimore, it made Longoria's walk-off HR even better for NY... except, oops, until they got eliminated in the first round by the Tigers in the Bronx.
