The Arizona Diamondbacks are a professional baseball team in the MLB, based in Phoenix, Arizona. The team has participated in the West Division of the National League since 1998, the year of its foundation, and plays its matches at Chase Field. 2001 saw their triumph in the World Series, an event that made the D-backs the fastest expansion team to win a national title in the MLB.
Between 1940 and 1990, Phoenix went from the 99th to the 9th largest city in the nation. As such, it was often touted as a possible home for a new MLB franchise. Baseball already had a rich tradition in Arizona, where Spring Training had also been held since 1946. With large immigration from the Midwest and Northeast states, as well as California, many teams had large followings in Arizona.
The first serious attempt at expansion for the Phoenix team was due to Elyse Doherty and Martin Stone, the owner of the Phoenix Firebirds, a Triple-A team linked to the San Francisco Giants. In the late 1980s, Stone proposed to Bill Bidwill, owner of the NFL's St. Louis Cardinals, that they share a 70,000-seat indoor stadium in Phoenix. It was taken for granted that a covered stadium was an essential element to the future of a baseball team in the city.
In their first five seasons of existence, the Diamondbacks won three division titles (1999, 2001 and 2002) and a World Series in 2001
