PULLMAN, Wash. - Southern California's first game away from its perpetually sunny home in more than a month was a cold and wet rout.
Reggie Bush and LenDale White each scored two touchdowns, Dwayne Jarrett caught two more TD passes from Matt Leinart and the top-ranked Trojans beat Washington State 42-12 Saturday.
USC jumped out to a quick 21-0 lead and coasted to its 17th straight victory and 12th straight conference win.
"They came out of the chutes just flying," USC coach Pete Carroll said. "I'm really excited about our ability to jump on the opportunities and maximize early in the game. They really took over the game very early. Both sides of the ball were clicking. I like the way we were pushing all the way through the first half."
The Trojans rolled up 426 yards and held the Cougars to 156, sacking quarterback Alex Brink five times, forcing seven fumbles and limiting the Cougars to minus-9 yards rushing.
Leinart completed 23 of 28 passes for 235 yards and helped build a 42-0 lead before being replaced for part of the third quarter by backup Matt Cassell. After Cassell miscues led to WSU scores, Leinart finished the game.
The Trojans scored on their first two possessions with Bush sweeping around the right end for a 19-yard touchdown to start the rout.
USC's Desmond Reed recovered a botched kickoff at the WSU 21, setting up White's 1-yard score, and just like that it was 14-0.
Bush's 57-yard punt return gave USC a 21-0 lead midway through the first quarter.
"We came out and dominated early, which was one of our main focuses," Bush said.
The Trojans were so dominant, punter Kyle Basler's 17-yard scamper on a fake led all Cougar rushers.
The Trojans were coming off three straight home games and four straight in California, going back to the game at Stanford on Sept. 25. Their last game outside California was Sept. 18 at BYU. It was the first time a No. 1 team has played in Martin Stadium.
UCLA 21, STANFORD 0: The Bruins' defense, which had been one of the nation's most generous, suddenly turned stingy.
Led by linebackers Spencer Havner and Justin London, the Bruins got their first conference shutout in 17 years.
Maurice Drew scored touchdowns on a 68-yard punt return and a 3-yard reception, and Manuel White ran 2 yards for UCLA's other touchdown. The victory was the Bruins' first this season against a team that had a winning record.
OREGON ST. 28, ARIZONA 14: Derek Anderson threw for two touchdowns and ran for another, breaking the Beavers' career passing and total offense records.
Oregon State won its third in a row, all against conference opponents. Arizona lost its seventh straight, and seventh in a row in the Pac-10, dating to last season.
Anderson completed 17 of 31 passes for 249 yards. The senior quarterback has thrown for 9,976 yards, breaking the record of 9,680 set by Jonathan Smith from 1998-2001.
Richard Kovalcheck, the redshirt freshman in his second start, was 19-for-38 for 235 yards and a touchdown but was intercepted twice. Arizona had gone 103 minutes - six-plus quarters - without a score when, on fourth-and-seven, Kovalcheck threw short to Biren Ely, who broke tackles, barely stayed inbounds, then stretched the ball over the goal line on a 27-yard play with 2:33 left in the third quarter.
OREGON 31, WASHINGTON 6 Kellen Clemens found freshman Cameron Colvin with a pair of touchdown passes to lead the Ducks.
Defensive end Chris Solomona also returned an interception 8 yards for another score for the Ducks, who have won four straight games after losing three of their first four.
Coming off its first shutout loss in 23 years, Washington was again punchless offensively. Evan Knudson kicked a pair of field goals for the Huskies, who have lost three straight. Washington's lone victory this season came at home against San Jose State.
