As a result of the September 11 attacks, the start of the playoffs was delayed and the season's end was extended past the usual October timeframe. The Yankees advanced to the 2001 World Series to face the Arizona Diamondbacks. Game 4 marked the first time that any non-exhibition MLB game had been played in the month of November. In extra innings, Jeter hit a game-winning home run off of Byung-hyun Kim. The words "Mr. November" flashed on the scoreboard, alluding to former Yankee Reggie Jackson's nickname, "Mr. October." Despite the home run, Jeter slumped at the plate; he denied injuries were a factor, though a fall into a photographer's box trying to catch a foul ball may have aggravated an earlier hamstring injury. Jeter batted .148 in the World Series, as the Yankees lost in seven games.
