Jordan Williamson hit a 37-yard field goal in overtime and No. 14 Stanford upset No. 1 Oregon 17-14, denying the Ducks a chance to clinch the Pac-12 North and derailing their straight shot at the BCS championship game.

If both Stanford and Oregon finish with wins in their final games next weekend, both will finish with one conference loss, which means Stanford will win the head-to-head matchup and go to the Pac-12 championship game for a chance to play in the Rose Bowl.

Stanford (9-2, 7-1) will visit No. 17 UCLA, which defeated No. 21 USC 38-28 earlier in the day to claim the Pac-12 South. Oregon (10-1, 7-1) will play rival Oregon State in the annual Civil War rivalry game in Corvallis.

The loss snapped a 13-game winning streak for the Ducks, which was longest current streak in the nation. It was Stanford's fifth straight win.

Oregon's loss, coupled with Kansas State's — they were also the top two teams in the BCS standings — means Notre Dame is now the lone unbeaten team in the race for the BCS title game.

The Fighting Irish now control their national championship race and Alabama and a couple of other Southeastern Conference teams are also in the thick of it.

Oregon was the only Pac-12 team that Stanford hadn't defeated over the past two seasons. But Cardinal's tough defence smothered the highest scoring team in the nation.

Alejandro Maldanado missed a 41-yard field goal for the Ducks to open overtime.

Redshirt freshman Kevin Hogan threw for 211 yards and a game-tying fourth-quarter touchdown for Stanford, while Stepfan Taylor rushed for 161 yards on 33 carries.

Down 14-7, Stanford went for it on fourth-and-1 on the Oregon 12 with 2:17 left in regulation and Ryan Hewitt ran for the first down, Hogan hit Zach Ertz with a 10-yard scoring pass to tie it at 14 with 1:35 to go. Ertz fought to gain control of the ball with a defender as he fell to the turf on top of a Ducks player. The play was initially ruled incomplete, but a video review overturned it for the game-tying touchdown.

Despite a pass interference call gave them a crucial first down, the Ducks were forced to punt on the ensuing series and Stanford took over with 36 seconds to go and the game went to overtime.

Baylor blitzes Wildcats

Collin Klein and second-ranked Kansas State can still get to a BCS game. Getting to the BCS championship game is all but lost.

Glasco Martin ran for three touchdowns, Lache Seastrunk had 185 yards rushing with an 80-yard score and Baylor again upset the BCS picture with a late-season victory, beating the Wildcats 52-24 Saturday night.

A week after the Wildcats (10-1, 7-1 Big 12) took over the No. 1 spot in the BCS standings following defending national champion Alabama's loss, it now looks like it's going to somebody else's turn at the top.

Maybe Notre Dame, which could get its championship shot after Kansas State and No. 1 Oregon both lost. And the Crimson Tide suddenly is back in the title picture, along with a couple other SEC teams.

Also, K-State quarterback Collin Klein may be a Heisman Trophy front-runner no more after throwing three interceptions and getting sacked twice while being pressured and harassed all night. He threw for 286 yards, but had only 39 yards on 17 carries.

On first-and-goal from the 6 in the fourth quarter, Klein had four straight carries and couldn't score — twice trying from the 1.

Nick Florence, the successor to Heisman winner Robert Griffin III, threw for 238 yards. Both of his touchdowns came in the first half when the Bears (5-5, 2-5) jumped out to a 28-7 lead.

It was on the same weekend last November, on another Saturday night in Waco, when Griffin and Baylor upset then fifth-ranked Oklahoma after two teams ahead of the Sooners had already lost that day.

Kansas State has plenty of time for this loss to simmer. The Wildcats have Thanksgiving week off before playing their regular season finale Dec. 1 at home against No. 18 Texas.

If the Wildcats beat Texas, they will be guaranteed at least a share of the Big 12 title and get the league's automatic BCS spot.

That may be the only solace after such a crushing loss against Baylor.

Klein, who finished 27-of-50 passing, had thrown only three interceptions the first 10 games.

After Martin's 2-yard TD put Baylor up 28-7 with 2:54 left in the first half, Kansas State scored 10 consecutive points before the break — and then got the ball to start the second half, only to have Klein throw his second interception.

Martin finished with 113 yards rushing.

There was a classic 13-yard run by Klein to start the second half, then two deep incompletions before he was picked off by Sam Holl, who returned it to the Kansas State 38. Four plays later, after a Florence 13-yard keeper, Martin scored on a 4-yard run to make it 35-17.

The Wildcats then got a 50-yard kickoff return from Tramaine Thompson, but Klein had three consecutive incompletions leading to a punt that pinned Baylor at its 1.

Florence threw an interception, Randall Evans grabbing the ball at the 1 but immediately getting dragged down by intended receiver Terrance Williams. Klein plunged in from a yard out on the next play, but that would be the last score for the Wildcats.

On the first play after Klein was picked off in the end zone late in the third quarter, Seastrunk took a handoff and raced 80 yards for the score.

Chris Harper had 11 catches for 123 yards.

Fighting Irish blow out Demon Deacons

Wake Forest had no answers for No. 3 Notre Dame.

The Demon Deacons fell behind quickly by three touchdowns en route to a 38-0 loss to the Fighting Irish on Saturday.

Wake Forest fell to 1-33 all-time against teams ranked in the top 5, the lone victory coming against No. 4 Tennessee in 1946. Wake Forest could do nothing to end that streak.

The Irish (11-0) scored on the fourth play of the game on a 68-yard run by Cierre Wood, who finished with 150 yards rushing on 11 carries.

Three plays later, Wake tailback Josh Harris caught a 13-yard pass but fumbled after a hard hit by Irish linebacker Carlo Calabrese and safety Zeke Motta recovered.

Harris, Wake Forest's leading rusher, didn't play the rest of the game because of a head injury.

The Irish scored two more touchdowns and the rout was on. Grobe said he'd like to say the fumble gave the Irish momentum, but said Notre Dame was just too much for the Deacons (5-6).

Tanner Price was 22 of 33 passing for 153 yards for Wake Forest with his longest pass for 16 yards. The Irish held the Demon Deacons to 55 yards rushing as Wake Forest dropped to 1-4 on the road this season.

The victory reinforced Notre Dame coach Brian Kelly's opinion that his team is the best after seeing Everett Golson throw three touchdown passes to finish the season undefeated at home for the first time since 1998 and keep its national championship hopes alive.

Kelly, who saw his 12-0 Cincinnati team left out of the BCS title game in 2009, said he has no doubt his 11-0 team deserves to play for the championship if they win the season finale at Southern California. That's all he wants his players focused on, he said.

"They cannot do anything else but beat USC," Kelly said. "The rest is up to other people to decide."

After posting a 17-16 record at home the past five seasons, the Irish victory Saturday improved their record at Notre Dame Stadium to 6-0 this year.

But this was the first time they made it look easy.

The Irish needed overtime to beat Stanford, triple overtime to beat Pittsburgh and won the three other home games by a combined 13 points.
