The 2001 Major League Baseball season, the first of the 21st century, finished with the Arizona Diamondbacks defeating the New York Yankees in a Game 7 of the 2001 World Series. The September 11 terrorist attacks on New York and Washington, D.C. pushed the end of the regular-season from September 30 to October 7. Because of the tragedy, the World Series was not completed until November 4; therefore, it was called The November Series. The 2001 World Series was the only World Series to end in November, until the 2009 Series, which was scheduled to end on November 1 at the earliest and ended on November 4.
