Major league baseball had never been played in November before Jeter stepped to the plate against Diamondbacks closer Byung-Hyun Kim with two outs in the bottom of the 10th inning of Game 4 of the World Series. As the clock struck midnight, flipping the calendar to November, Jeter fell in, then battled out of, an 0-2 hole, and hit the ninth pitch of the at-bat just over the wall in rightfield for a game-winning solo home run, the first walk-off homer of his career. The blast earned Jeter the nickname "Mr. November."
