The 2001 Arizona Diamondbacks, in their fourth year of existence, looked to improve on their 2000 season. They had to contend in what was a strong National League West Division.
Arizona had the best one-two pitching combination in the majors: Curt Schilling and Randy Johnson, who combined for 43 victories. Outfielder Luis Gonzalez slugged 57 home runs. They finished the regular season with a record of 92-70, which was good enough for the division title.
In the playoffs, they won their NLDS matchup vs. St. Louis on a walk-off hit by Tony Womack. They defeated the Braves in five games in the NLCS. In the World Series, they won a dramatic seven-game series against the New York Yankees on a walk-off hit by Gonzalez, against Yankees closer Mariano Rivera. The Arizona Diamondbacks became the fastest expansion franchise in Major League Baseball history to win a World Series title in just their fourth season.
