October 25, 2003 - The Florida Marlins defeat the NY Yankees 4-2 in the World Series. The Yankees did not return to the World Series until 2009.
"The series headed back to New York for Game 6, marking the 100th World Series game ever played at Yankee Stadium. Marlins manager Jack McKeon decided to start 23-year-old Josh Beckett on three days' rest. Beckett made the move seem brilliant—his complete game shutout in the final game of the World Series made him the first to accomplish the feat since Jack Morris of the Minnesota Twins in 1991. With the victory, the Marlins became the first National League team since the 1981 Los Angeles Dodgers to win the World Series without having home field advantage."
