Prior to Arizona State University joining what would become the Pac-10 conference along with the University of Arizona in 1978, Oregon and the Sun Devils had only ever played a single home-and-home series in football. The Ducks flew south to Tempe on November 12, 1966 and the home team won the day 14-10. Arizona State finally made a return trip to Eugene on September 15, 1973 and were rude guests to their hosts, winning 26-20. The schools played seven times from 1980 to 1988 as conference opponents, every game an Arizona State victory. Oregon broke through in the win column in 1989 and 1990, in which head coach Rich Brooks and quarterback Bill Musgrave led the Ducks to their first bowl games since the time of coach Len Casanova.
