LOS ANGELES — Theo Riddick rushed for 146 yards and a touchdown, Kyle Brindza kicked five field goals, and No. 1 Notre Dame secured a spot in the BCS championship game with a 22-13 victory over Southern California Saturday night. Everett Golson passed for 217 yards as the Fighting Irish (12-0) completed their first perfect regular season since 1988, earning a trip to Miami on Jan. 7 to play for the storied program's first national title in 24 years. Although they did little with flash on an electric night at the Coliseum, the Irish woke up more echoes of past Notre Dame greats with a grinding effort in this dynamic intersectional rivalry with USC (7-5), which has lost three of four. No. 2 Alabama 49, Auburn 0: AJ McCarron passed for four touchdowns and Eddie Lacy rushed for 131 yards and two scores in the most lopsided Iron Bowl in 64 years. The Crimson Tide (10-1, 7-1 Southeastern Conference) clinched the Western Division title outright and a spot in the conference title game against No. 3 Georgia with the winner likely getting a national championship shot. No. 3 Georgia 42, Georgia Tech 10: Aaron Murray threw two touchdown passes, Todd Gurley and Keith Marshall each ran for a pair of TDs, and Georgia stayed right in the thick of the national championship race. The Bulldogs (11-1) extended the domination of the Yellow Jackets, beating their state rival for the 11th time in 12 meetings. This one was a laugher from the start as the home team scored just over a minute into the game, built a 28-3 halftime lead and was up 42-3 before Georgia Tech (6-6) scored its lone TD. No. 4 Ohio State 26, No. 20 Michigan 21: Carlos Hyde ran for 146 yards and Ohio State's defense shut out Michigan in the second half to complete a 12-0 season. It was a sweet win for the Buckeyes, just 6-7 last season with a loss to their archrivals in a transitional year in which they were facing heavy NCAA penalties. No. 5 Oregon 48, No. 16 Oregon State 24: Kenjon Barner ran for 198 yards and two touchdowns despite leaving the game for a time with an injury and the Ducks kept alive their hopes for a spot in the Pac-12 title game and even an outside chance at the national championship. De'Anthony Thomas, who helped picked up the slack while Barner was on the sidelines, ran for 122 yards and three scores for the Ducks (11-1, 8-1). No. 6 Florida 37, No. 10 Florida State 26: Mike Gillislee ran for two touchdowns and the Gators beat their rivals to stay in the national title hunt. Florida regained the lead 23-20 on Gillislee's 37-yard run with 11:01 left in the final period on the first play after Florida State's EJ Manuel fumbled, his fourth turnover of the game. Gillislee finished with 140 yards rushing. No. 11 Stanford 35, No. 15 UCLA 17: Stepfan Taylor rushed for 142 yards and two touchdowns, Kevin Hogan passed for 160 yards and another score, and No. 11 Stanford beat No. 15 UCLA to win the Pacific-12 Conference North title and a rematch with the Bruins in the conference championship game. In other action it was: No. 13 S. Carolina 27, No. 12 Clemson 17; Connecticut 23, No. 19 Louisville 20 3OT; Mississippi 41, No. 25 Mississippi St. 24; No. 25 Utah State 45, Idaho 9; Oklahoma 51, Oklahoma State 48; and Texas A&M 59, Missouri 29. — Agencies
