The Arizona Diamondbacks are tied with the Rays for being the youngest franchise in Major League Baseball. Arizona entered the league in 1998 and started off with a bang. The D-Backs made the playoffs three times in the franchise’s first five seasons. But did any of the Diamondbacks’ playoff runs over the years lead to World Series titles? Let’s find out.

When did the Diamondbacks last win a World Series title?

The Diamondbacks last won a World Series title in 2001.

How many World Series have the Diamondbacks won?

The Arizona Diamondbacks franchise has won one World Series title, not titles. That lone title came in 2001.

Arizona made the playoffs for the first time in 1999, a year after the Diamondbacks’ first season in the Majors. After a 97-loss season in 1998, Arizona would win 100 games that year to win the NL West in 1999.

The Diamondbacks were a literal unit, led by “The Big Unit” Randy Johnson and a lineup that featured Steve Finley, Matt Williams, and Luis Gonzalez. Despite that regular season success, the Diamondbacks would be bounced in the NLDS by the New York Mets.

Two seasons later, Arizona would return to the MLB Playoffs. The Diamondbacks returned with roughly the same team, along with two new additions: Reggie Sanders and Curt Schilling. Arizona took out St. Louis in the NLDS and then beat Atlanta in five games to move on to the World Series.

The 2001 World Series pitted the Diamondbacks against the defending champion New York Yankees. The Yankees had won three straight titles prior to 2001, but Arizona proved to be too much for the Yanks. In Game 7, Arizona outfielder Luis Gonzalez walked it off against Mariano Rivera to clinch the Diamondbacks’ first and only title to date.

As of the end of 2024, the Diamondbacks made the MLB Playoffs just five times since 2001. The closest Arizona came to a return trip prior to the D-Backs’ trip to the World Series in 2023 was in 2007, a year that saw the D-Backs advance to the NLCS before being swept by division rival Colorado.

Arizona returned to the World Series in 2023 but lost in five games to the Texas Rangers.
