Arizona Diamondbacks

The Arizona Diamondbacks (often shortened as the D-Backs) are an American professional baseball team based in Phoenix, Arizona. They play in the West Division of Major League Baseball's National League. Since the team's inception in 1998, the franchise has played home games at Chase Field, formerly known as Bank One Ballpark. The ballpark was renamed in 2005 as a result of Bank One Corporation's merger with JPMorgan Chase & Co. The Diamondbacks have won one World Series championship (in 2001), becoming the fastest expansion team in the major leagues to win a championship, doing it in only the fourth season since the franchise's inception in the 1998 Major League Baseball season.

Chase Field is a stadium located in downtown Phoenix, Arizona and is the home of the Arizona Diamondbacks of Major League Baseball. It opened in 1998, in time for the Diamondbacks' first game as an expansion team. Chase Field was the first stadium built in the United States with a retractable roof over a natural-grass playing surface.
