NEW YORK: Stanford is back on top of the Pac-12 North after Arizona did to Oregon what Southern California did to the Cardinal last week.

Though this upset was far more surprising and emphatic.

The fifth-ranked Ducks had their national championship hopes smashed by Arizona, 42-16 on Saturday as No. 10 Stanford was routing California.

The results give Stanford the Pac-12 North title for a second straight season. Oregon (9-2) might be able to get an at-large BCS bid if it can close out with a victory against Oregon State, but it's looking like a bit of a long shot now.

Oregon lost for the second time in three games. In the last three weeks the Ducks have lost to Stanford to give the Cardinal control of the division, then regained control when Stanford fell to USC, and now have given it away again.

Stanford has a chance to reach back-to-back Rose Bowls for the first time since the 1971 and '72 games.

No. 1 Alabama 49 Chattanooga 0: In Tuscaloosa, Ala., AJ McCarron passed for two touchdowns and became No. 1 Alabama's winningest quarterback.

McCarron completed 13 of 16 passes for 171 yards before leaving one drive into the second half of his final game at Bryant-Denny Stadium for the Crimson Tide (11-0). He improved to 36-2 as a starter, breaking a tie with Jay Barker for the school mark.

McCarron and Alabama got an easy tuneup for the Iron Bowl against No. 6 Auburn to determine the Southeastern Conference Western Division champion.

The Tide produced its third shutout of the year and blocked a field goal against the FCS Mocs (8-4).

No. 2 Florida State 80 Idaho 14: In Tallahassee, Fla., Jameis Winston threw for 225 yards and four touchdowns as No. 2 Florida State broke a school record for points in a game.

Florida State (11-0) broke the school record of 77 points scored in 1995 to remain unbeaten.

The Seminoles continue to focus on football while the ongoing sexual assault investigation of Winston casts a shadow over the program. State attorney Willie Meggs said Saturday it is unlikely that a final decision will be made before Thanksgiving on whether to charge the quarterback.

No. 3 Baylor 49 No. 11 Oklahoma State 17: In Stillwater, Okla., Clint Chelf passed for a career-high 370 yards and accounted for four touchdowns as Oklahoma State took down another national-championship hopeful.

Chelf, who lost the starting job earlier this season for the Cowboys (10-1, 7-1 Big 12 Conference), threw for three touchdown passes and ran for a score — continuing his mastery of the stunned Bears in front of a record crowd of 60,218 in Boone Pickens Stadium.

The senior also had a 48-yard reception and finished with 438 yards of total offense. He was 19-of-25 passing.

No. 4 Ohio State 42 Indiana 14: In Columbus, Ohio, Braxton Miller ran for 144 yards and two touchdowns and passed for two more Saturday to lead No. 4 Ohio State to a 42-14 victory over Indiana, extending the Buckeyes' school-record win streak to 23 in a row.

The snowy victory clinched a division title for the Buckeyes (11-0, 7-0), locking up a spot opposite Michigan State in the Big Ten championship game on Dec. 7.

Carlos Hyde became the first running back to go over 1,000 yards rushing in Urban Meyer's 12 years as a head coach. He ran for 117 yards and two scores.

Arizona 42 No. 5 Oregon 16: In Tucson, Ariz., Ka'Deem Carey ran for 206 yards and four touchdowns while becoming Arizona's all-time leading rusher.

Coming off a disappointing home loss to Washington State, Arizona (7-4, 4-4 Pac-12) didn't back off the throttle of its up-tempo offense against the fast-paced Ducks.

No. 10 Stanford 63 California 13: In Stanford, Calif., Ty Montgomery matched a Stanford school record with five touchdowns, scoring the first four times he touched the ball, and the Cardinal clinched a spot in the Pac-12 championship game with Oregon's loss.

Kevin Hogan threw four of his five scoring passes to Montgomery, including a 9-yard completion just before halftime that put Stanford ahead 42-13. The Cardinal (9-2, 7-2 Pac-12) bounced back from last week's loss at USC but needed No. 5 Oregon to lose one of its final two games to earn a spot in the conference championship. The Ducks lost 42-16 in Tucson, and Stanford's fans led chants of "Arizona! Arizona!"

Hogan set career highs with 329 yards passing and the five TD passes.

No. 7 Clemson 52 The Citadel 6: In Clemson, S.C., Tajh Boyd threw for five touchdowns and 288 yards in the final home game of his career.

The game was more of a celebration than a contest for the Tigers (10-1), who now have not lost in 28 games against Football Championship Subdivision opponents.

Clemson didn't score on its first possession, but made it to the end zone the next five times it touched the ball. Boyd had touchdown passes of 8, 9, 19, 24 and 30 yards. He ended the game with 102 passing TDs in his career and tied the Tigers record of five passing TDs in a game for the sixth time. Three times Boyd has thrown for five scores in the first half.
