Ka'Deem Carey ran for 206 yards and four touchdowns while becoming Arizona's all-time leading rusher, and the Wildcats took advantage of numerous Oregon miscues to shock the fifth-ranked Ducks 42-16 on Saturday.
Coming off a disappointing home loss to Washington State, Arizona (7-4, 4-4) didn't back off the throttle of its up-tempo offense against the fast-paced Ducks.
With Carey bursting through the line to punish defenders and B.J. Denker dinking and dashing with a variety of fakes, the Wildcats jumped out to a quick 14-0 lead and kept going for their first win over a top-five team since knocking off No. 1 Washington 1992.
Oregon (9-2, 6-2 Pac-12) gave the Wildcats plenty of help with three turnovers and turning it over twice more on downs to end its national title hopes and, possibly, its four-year run of BCS bowls.
