Oregon is the nation's top-ranked team for the first time in program history.
The Ducks are No. 1 in both the AP poll and the coaches' poll. The coaches' poll counts in the BCS standings, the first batch of which will be released today.
Stanford is 12th in the AP poll and No. 14 in the coaches' poll. Arizona is 15th in the AP poll and 18th in the coaches' poll.
The top five in both polls are identical. Each of the top-five teams -- Oregon, Boise State, Oklahoma, TCU and Auburn -- received first-place votes. But Oregon's 42 first-places votes were well ahead of Boise State's 11 in the coaches' poll.
Oregon plays host to UCLA on Thursday.
