Formerly Bank One Ballpark, Chase Field is the retractable-roof stadium you face in downtown Phoenix, Arizona. This is the ballpark of Major League Baseball's Arizona Diamondbacks; it opened in 1998, the year the Diamondbacks debuted as an expansion team. When it opened it was the first stadium built in the United States with a retractable roof over a natural grass playing surface, though it has used artificial turf since 2019.
The park was built during a wave of new, baseball-only parks in the 1990s, but here a dome was taken for granted: Phoenix is by far the hottest major city in North America, with an average high during baseball's regular season of 99.1 °F (37.3 °C), and game-time temperatures well above 100 °F (38 °C) are common in summer. You can also think about how local funding shaped this place: in the spring of 1994 the Maricopa County Board of Supervisors approved a 0.25 percentage point increase in the county sales tax to pay for their portion of the stadium funding. Notice the retractable roof and downtown Phoenix beyond it.
