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, just in time for the Diamondbacks' first game as an expansion team. Chase Field was also the first stadium built in the United States with a retractable roof.

In the spring of 1994, the Maricopa County Board of Supervisors approved a quarter-cent increase in the county sales tax to pay for their portion of the stadium funding. This came about at a time that the county itself was facing huge budget deficits and lack of funding for other services. The sales tax being levied was very unpopular with local citizens, who were not allowed to vote on the issue of funding a baseball stadium with general sales tax revenue (usage of public subsidies for stadium projects was actually prohibited by a 1989 referendum). The issue was so controversial and divisive that in August 1997, Maricopa County Supervisor Mary Rose Wilcox was shot and injured while leaving a county board meeting by Larry Naman, a homeless man, who attempted to argue in court that her support for the tax justified his attack. In May 1998, Naman was found guilty of attempted first-degree murder.
