Chase Field is a baseball park located in Downtown Phoenix, Arizona. It is the home of the Arizona Diamondbacks, the city's Major League Baseball (MLB) franchise. It opened 18 years ago 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.(Wikipedia)
