Cliff Harris returned a punt 64 yards for the only touchdown in the first half by the Ducks (10-0, 7-0 Pac-10), who wobbled on the road to the BCS title game.

Darron Thomas led a final drive that chewed up the last 9:32 after a stellar defensive effort by the Bears, who held the nation’s most potent offense to a season-low in yards.

Giorgio Tavecchio missed a 29-yard field goal in the fourth quarter for Cal that would have given the Golden Bears a 16-15 lead. The miss came after he was called for a false start that wiped a 24-yard field goal off the board.

No. 2 Auburn 49, Georgia 31: At Auburn, Alabama, Cam Newton responded to allegations of wrongdoing by passing for two touchdowns and running for two more to lead Auburn into the SEC championship game.

The Tigers (11-0, 7-0) will face South Carolina for the conference title Dec. 4 in Atlanta, and have their eyes on a national championship.

Newton carried 30 times for 151 yards and completed 12 of 15 passes for 148 yards. He finished off the Bulldogs in the fourth quarter with a touchdown pass that made it 42-31, then dove over for the final score.

Georgia (5-6, 3-5) had won four straight in the Deep South’s oldest rivalry and jumped ahead 21-7. But the Bulldogs couldn’t hold on, despite A.J. Green’s nine receptions for 160 yards.

No. 3 TCU 40, San Diego State 35: At Fort Worth, Texas, Andy Dalton threw three touchdown passes to Jeremy Kerley as TCU rallied from an early two-touchdown deficit, then held on to beat San Diego State.

The Horned Frogs (11-0, 7-0 Mountain West) won their 20th consecutive home game and clinched at least a share of the conference title. They also kept alive their chance to reach the BCS national championship game, but it’ll be interesting to see how poll voters react to the Horned Frogs’ closest game of the season.

San Diego State (7-3, 4-2) led 14-0 less than 6 minutes into the game, before TCU scored touchdowns on five of its last six drives before halftime. The Aztecs didn’t have a first down in that stretch, but three TDs in the final 16 minutes of the game made it close.

No. 5 LSU 51, Louisiana-Monroe 0: At Baton Rouge, Louisiana, Ron Brooks returned an interception for a score, Lavar Edwards brought back a fumble for another, and LSU’s defense dominated.

It was an anticlimactic victory for the Tigers (9-1), who were eliminated from contention in the SEC’s Western Division with Auburn’s victory over Georgia. LSU still can finish its regular season 11-1 and earn an at-large bid to a BCS bowl.

LSU’s defense produced five turnovers in all, leading to 30 points, and LSU built a 44-0 lead by the third quarter.

No. 6 Wisconsin 83 Indiana 20: At Madison, Wisconsin, Montee Ball ran for three touchdowns in his first start, replacing injured running back John Clay, and Scott Tolzien threw for three more scores as Wisconsin matched the highest-scoring game by a Big Ten team in 60 years.

The Badgers (9-1, 5-1) put up the most points by an FBS school this season and matched the highest scoring total by a team in a Big Ten conference game since Ohio State’s 83-21 victory over Iowa in 1950.

Ball ran for 167 yards and freshman James White added 144 yards and two scores in place of Clay, who missed the first game of his career after spraining his right knee last Saturday.

No. 7 Stanford 17, Arizona State 13: At Tempe, Arizona, Andrew Luck threw for 292 yards and engineered a long fourth-quarter scoring drive to set up Owen Marecic’s second 1-yard touchdown dive.

Stanford (9-1, 6-1 Pac-10) labored against Arizona State’s gang-tackling most of the night before moving 85 yards in 10 plays to set up Marecic’s bulldozing TD run with just over 5 minutes left.

The Cardinal made up for their offensive struggles with hard-nosed defense, holding the Sun Devils (4-6, 2-5) to 268 total yards to win in Tempe for the first time since 1999.

Arizona State played another good team tough, again failing to come up with big plays down the stretch.

No. 8 Ohio State 38 Penn State 14: At Columbus, Ohio, Devon Torrence tipped and snagged an interception and returned it 34 yards for the go-ahead touchdown to turn the tide for the Buckeyes.

Ohio State, which trailed 14-3 at half, added scores when a long pass into double coverage ricocheted off a defender to Dane Sanzenbacher for a 58-yard score and Travis Howard picked off a pass and brought it back 30 yards, also in the fourth quarter.

The two defensive scores were nothing new in the series.

Penn State (6-4, 3-3 Big Ten) has had six interceptions returned for TDs in the last seven meetings.

No. 9 Nebraska 20 Kansas 3: At Lincoln, Nebraska, Rex Burkhead and Roy Helu Jr. ran for touchdowns and Nebraska’s defense held Kansas to 87 total yards.

Nebraska quarterback Taylor Martinez was limited by design after missing all but one play of last week’s game at Iowa State with a right ankle sprain. He clearly wasn’t at his best, but he showed glimpses of his dynamic running ability, gaining 71 yards on 11 carries.

Martinez was 14 of 26 passing for 167 yards, with one interception.

Helu had 85 yards and Burkhead 77 yards.

No. 11 Alabama 30, No. 17 Mississippi State 10: At Tuscaloosa, Alabama, Greg McElroy passed for 227 yards, including a 78-yard touchdown to Mark Ingram, and Alabama rolled over Mississippi State.

The Crimson Tide (8-2, 5-2 Southeastern Conference) showed it can still dominate even the improved version of the Bulldogs (7-3, 3-3) after its title hopes evaporated.

The Tide used big plays to punch up the offense after the Bulldogs kept Ingram and the short-handed running game from producing much. Instead, Alabama had scores of 45, 78 and 56 yards on three consecutive offensive plays starting in the second quarter to run away with it.

No. 12 Oklahoma State 33, Texas 16: At Austin, Texas, Brandon Weeden passed for 409 yards and Kendall Hunter ran for two touchdowns as Oklahoma State ended a 12-year losing streak to Texas.

The win keeps surging Oklahoma State (9-1, 5-1) in first place in the Big 12 South with two games to play. The Cowboys have never won the division.

Hunter ran for 116 yards. Justin Blackmon had 145 yards receiving for the Cowboys, including a 67-yard touchdown catch in the second quarter, his 16th of the season, the most in the nation.

The loss is just the latest home defeat for the reeling Longhorns (4-6, 2-5) who have lost six of their last seven games — four straight at home — just one season after playing for the national championship.

Texas must win its last two games to avoid its first losing season since 1997 and qualify for a bowl game.

Notre Dame 28 No. 15 Utah 3: At South Bend, Indiana, freshman Tommy Rees threw three touchdown passes in his first start and Notre Dame used two Utah special teams mistakes to rout the slumping Utes.

Returning from a week off, Notre Dame (5-5) moved within one win of becoming bowl eligible. Utah (8-2), meanwhile, was still reeling from its 47-7 loss to TCU a week earlier.

The victory was Notre Dame’s first over a ranked team since 2006, when the Irish defeated Penn State.

USC 24 No. 18 Arizona 21: At Tuscson, Arizona, Marc Tyler ran for a career-high 160 yards and Southern California climbed into a tie with Arizona for third in the Pac-10 .

Matt Barkley passed for one touchdown and sneaked for another as the Trojans (7-3, 4-3 Pac-10) jumped ahead 14-0 and never relinquished the lead.

The Wildcats’ Nick Foles threw for 353 yards and three touchdowns, the last an 11-yarder to David Douglas with 1:01 to play. But USC recovered the subsequent onside kick to preserve the victory.

Arizona (7-3, 4-3) lost its second in a row. The Wildcats were blown out at Stanford 42-17 last weekend.

No. 22 South Carolina 36, No. 24 Florida 14: At Gainesville, Florida, Marcus Lattimore ran 40 times for a career-high 212 yards and three touchdowns, Stephen Garcia played turnover-free and Steve Spurrier’s Gamecocks upset Florida to clinch the Southeastern Conference’s Eastern Division.

The Gamecocks won for the second time in 19 tries against Florida, snapped an 0-for-12 streak in Gainesville and earned a spot in the league title game for the first time.

South Carolina (7-3, 5-3 SEC) will play second-ranked Auburn on Dec. 4, with the winner advancing to the Bowl Championship Series.
