EUGENE — Oregon is a four-score favorite against winless Arizona.
The No. 4 Ducks (3-0) opened as 27-point favorites against the Wildcats (0-3) Saturday (7:30 p.m. PT, ESPN) in an early line posted to VegasInsider.com.
Oregon leads the all-time series 27-17 and top 10-ranked Ducks teams have lost three of the last five times against unranked Wildcats teams, though UO won 34-6 in the last meeting in 2019.
Oregon is 1-1-1 against the spread this season, failing to cover as a favorite against Fresno State, winning straight up as an underdog at Ohio State and a push against Stony Brook.
