Oregon went 92 yards in 15 plays on its first possession, and Shough hit tight end DJ Johnson with a 13-yard scoring pass for a 7-0 lead.
Washington State replied with an 18-yard touchdown pass from de Laura to Lucas Bacon. The Cougars attempted a 2-point conversion but de Laura's pass was incomplete.
Dye fumbled on the next possession and Hector recovered for the Cougars near midfield.
