The Arizona Diamondbacks squeezed a lifetime of franchise history into a remarkably short run. Established in 1995 and launched as an expansion team in 1998, the D-backs play in the National League West and host games at Chase Field in Phoenix, a ballpark that opened as Bank One Ballpark and took its current name in 2005. Along with the Tampa Bay Rays, they are one of the two newest franchises in Major League Baseball, and they remain the youngest franchise ever to win a World Series. For fans weighing Diamondbacks tickets, that youth is part of the appeal: every milestone in franchise history happened within living memory of the first pitch.
The climb was unusually fast. After a fifth-place finish in their inaugural season, Arizona acquired future Hall of Fame pitcher Randy Johnson, who responded with four consecutive Cy Young Awards between 1999 and 2002. The 1999 club won 100 games and the first division title in franchise history, and in 2001 the Diamondbacks beat the three-time defending champion New York Yankees in a seven-game World Series, becoming the fastest expansion franchise in baseball history to win a title. It also made them the first men's major professional sports team in Arizona to win a championship. Two decades later, the 2023 team defeated the Philadelphia Phillies in Game 7 of the NLCS to claim a second National League pennant before falling to the Texas Rangers in the World Series.
The franchise ledger now reads five NL West titles, two National League pennants, and two Wild Card berths, with division crowns in 1999, 2001, 2002, 2007, and 2011. Randy Johnson and Roberto Alomar are the Diamondbacks names in the National Baseball Hall of Fame, and Johnson's plaque shows him wearing a Diamondbacks cap. The organization has retired Luis Gonzalez's number 20 and Johnson's number 51, and in 2024 the two became the inaugural inductees into the team's own Hall of Fame.
