Dave Roberts steal in Game 4 of 2004 ALCS
Without tallying a hit, Dave Roberts saved the Red Sox from elimination and propelled them to their first World Series title since 1918. Down 3-0 to the Yankees in the ALCS, the Red Sox looked doomed when Mariano Rivera stepped on the mound to close out Game 4. Rivera though, walked Kevin Millar, and Roberts came in as a pinch-runner. And then Roberts made the decision to steal second. As Joe Posnanski wrote, that steal convinced the Red Sox they could win Game 4, and from there on they were unstoppable. They swept Games 5, 6 and 7 from the Yankees and then beat the Cardinals in four straight in the Fall Classic.
