In 1966 the Cubs would move away from the Phoenix Metro area to Long Beach California's Blair Stadium and then Scottsdale soon after, but were lured back to Mesa 2 years after the opening of the new HoHoKam Park I in 1977. Rendezvous Park remained without a tenant for three years and would go dark until 1969 when the Oakland A's came to town. The Athletics had been utilizing Bradenton's McKechnie Field but came out west in
1969 to be closer to home. They would remain at Rendezvous Park for the rest of this stadium's existence, playing their final game here in 1976, when the ballpark was demolished. The A's still were under contract with the city of Mesa and would spend the following two springs playing at the brand new HoHoKam Park. In their 8 years here at Rendezvous Park, the Athletics would train 6 Hall Of Famers here… including Rollie Fingers, Catfish Hunter, Orlando Cepeda, Willie McCovey, Reggie Jackson and Billy Williams and they would field 3 Championship teams here from 1974-1976.
