LOS ANGELES — As expected, the Washington-USC game was a one-sided affair from the start. And now, the hapless Huskies stand alone as the nation's only winless major team.

Mark Sanchez completed 15 of 19 passes for 167 yards and two touchdowns to Patrick Turner before coming out early in the third quarter, and No. 7 Southern California scored TDs on its first six possessions and routed the Huskies 56-0 today.

C.J. Gable gained 108 yards on 10 carries and scored twice for USC, which led 42-0 at halftime. The Trojans had 18 first downs and 325 yards of total offense in the first half to two first downs and 35 yards for the Huskies.

USC emptied its bench in the second half.

The win before a homecoming crowd of 80,216 at the Los Angeles Coliseum was the 42nd in the last 43 home games for the Trojans (7-1, 5-1), and kept them alive in the national championship race. They're 24-0 in November games since Pete Carroll was hired as coach in 2001.

USC is one of three Pac-10 teams with one loss in conference action, along with Oregon State and California. The Trojans face the Golden Bears (6-2, 4-1) next Saturday at the Coliseum.

The Huskies (0-8, 0-5) are at the other end of the spectrum. They entered the weekend as one of two Division I-A teams without a victory, but North Texas rallied to beat Western Kentucky 51-40 for its first win of the year.

Washington coach Tyrone Willingham was fired last Monday, effective at season's end. His Huskies have a 12-33 record in three-plus seasons. The Huskies have began a season with eight straight losses for just the second time in school history. The 1969 team started 0-9.

The win was the most lopsided in the history of the 78-game series, surpassing USC's 48-0 triumph in 1929. The Trojans have won the last seven games between the teams, but their margin of victory was just six points in 2006 and three points last season.

The shutout was USC's third in their last four games. Since losing 27-21 at Oregon State last month, the Trojans have outscored their five opponents 207-27. They've allowed seven touchdowns in eight games and given up an average of 7.1 points per game.

The Huskies have played their last five games without star quarterback Jake Locker, who broke his right thumb Sept. 27 in a 35-28 loss to Stanford. Redshirt freshman Ronnie Fouch was ineffective against the Trojans, going 14-of-33 for 113 yards with three interceptions — two in USC territory in the fourth quarter.

USC took a 21-0 lead in the first 11½ minutes on touchdown passes of 4 and 32 yards from Sanchez to Turner and a 9-yard run by Gable.

Sanchez's 1-yard sneak on fourth down early in the second quarter made it 28-0 after the Huskies held Stanley Havili to no gain, but were penalized for lining up in the neutral zone.

Stafon Johnson scored on a 1-yard run just 91 seconds later, two plays after Rey Maualuga intercepted a pass by Fouch at the Washington 16-yard line.

The Huskies finally got a first down on their sixth possession, but were then forced to punt, and that meant another USC touchdown, this one by Gable on a 6-yard run that capped a 71-yard march.

Washington finally crossed midfield for the first time late in the second quarter on a pass interference penalty against Kevin Thomas, but the Huskies turned the ball over on downs at the 38-yard line.

USC made it 49-0 late in the third quarter, scoring on a 5-yard run by Broderick Green that capped a 68-yard drive.

Washington moved to the Trojans' 6-yard line early in the final period, but Chris Galippo intercepted a pass by Fouch on a second-and-goal play and returned it 50 yards to the Huskies' 49, setting up a 6-yard run by Marc Tyler with 8:02 remaining that completed the scoring.

Tyler gained 85 yards on 16 carries in the first extended action of his career.
