The Arizona Diamondbacks (colloquially known as the D-backs) are an American professional baseball team based in Phoenix, Arizona. The Diamondbacks compete in Major League Baseball (MLB) as a member club of the National League (NL) West division. On March 9, 1995, Phoenix was awarded an expansion franchise to begin play for the 1998 season. A $130 million franchise fee was paid to Major League Baseball and on January 16, 1997, the Diamondbacks were officially voted into the National League. The Arizona Diamondbacks’ first major league game was played against the Colorado Rockies on March 31, 1998, at Bank One Ballpark. The ballpark was renamed Chase Field in 2005. Along with the Tampa Bay Rays, the Diamondbacks are one of the newest teams in MLB. After a fifth-place finish in their inaugural season, the Diamondbacks made several off-season acquisitions, including future Hall of Fame pitcher Randy Johnson, who won four consecutive Cy Young Awards in his first four seasons with the team. In 1999, Arizona Diamondbacks won 100 games and their first division championship. In 2001, they won the World Series over the three-time defending champion New York Yankees, becoming the fastest expansion team in major league history to win the World Series, and the only men’s major professional sports team in the state of Arizona to win a championship. From 1998 to 2022, the Diamondbacks have an overall record of 1,914 – 2,034. Since their debut, the Diamondbacks have won five NL West division titles, one NL pennant, one Wild Card game, and the 2001 World Series.
