Chase Field™

Chase Field is a baseball park located in Downtown Phoenix,It is the home of the Arizona Diamondbacks, the city's Major League Baseball (MLB) franchise. It opened a while time 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. The park was built during a wave of new, baseball-only parks in the 1990s. Although nearly all of these parks were open-air, it was taken for granted that a domed stadium was a must for a major-league team to be a viable venture in the Phoenix area. Arizona is by far the hottest major state in North America; the average high temperature during baseball's regular season is 99.1 °F (37.3 °C), and game-time temperatures well above 100 °F (38 °C) are very common during the summer.
