1937: Renovated with Works Progress Administration funds, Bisbee's Warren Ballpark hosts its first game between professional baseball teams. The Chicago Cubs beat their cross-town-rival White Sox, 9-2. Windy City baseball fans were able to tune into the game on Chicago station WJJD through a live remote feed made possible by Bisbee radio station KSUN.

1992: Donald Eugene Harding is executed by lethal gas at the state prison in Florence for the 1980 murders of two businessmen in Phoenix. Harding, 43, is the first person executed in the state (since Manuel Silvas in 1976) and is the last to be executed while the gas chamber was the official execution method, partially due to the 11 minutes it took before death by asphyxiation could be confirmed.
