LOS ANGELES (AP) - Carson Palmer threw a pair of touchdown passes to Mike Williams, and Southern California's defense shut down Oregon State as the No. 18 Trojans beat the No. 23 Beavers 22-0 Saturday in their Pac-10 opener.
USC (3-1, 1-0) was coming off a rugged opening stretch of three nonconference opponents, while previously unbeaten Oregon State (4-1, 0-1) piled up yards and points against a relatively soft nonconference schedule.
DeShaun Hill had six tackles and Mike Patterson had two of five sacks to lead the Trojans' smothering defense, which held the Beavers to 131 yards as a Dennis Erickson-coached team was shut out for just the second time.
In his 17th college season, Erickson's only other shutout came in Miami's 29-0 loss to Arizona in the 1994 Fiesta Bowl. During Erickson's four years of coaching Seattle in the NFL, the Seahawks were not shut out.
The Beavers came into the game averaging 499.8 yards, second in the nation.
The loss was Oregon State's 28th in the last 29 games against the Trojans and the 19th straight at the Coliseum dating back to 1960. The Beavers beat USC at Corvallis in 2000. USC holds a 55-8-4 edge, including 37-4-3 in Los Angeles.
Palmer went 23-of-41 for 231 yards with one interception. He connected with Williams on a scoring throw of 11 yards just before halftime and added a 16-yard TD pass in the third quarter.
Ryan Killeen added three field goals for the Trojans, who had 330 yards of offense.
The Beavers' Derek Anderson, who entered the game ranked second nationally in passing efficiency, was just 8-of-30 for 80 yards and lost two fumbles.
Both USC touchdowns, and one of Killeen's field goals, followed Oregon State turnovers.
Patterson recovered an Anderson fumble at the OSU 20 to set up Killen's 42-yarder that made it 6-0, and Shaun Cody recovered another Anderson fumble at the USC 39 before the Trojans drove to their first touchdown.
A fumbled snap by Oregon State punter Carl Tobey gave USC the ball at the Beavers' 12 to set up Palmer's second scoring throw.
Palmer threw an 11-yard scoring pass to Williams, all alone in the end zone, 10 seconds before halftime as the Trojans opened a 13-0 lead.
The Beavers' Ryan Cesca, who missed two field goal tries in the fourth quarter of a 16-13 overtime loss to USC last season, was wide right on a 42-yarder in the first quarter for Oregon State's only real scoring threat of the game.
On Palmer's first touchdown pass, he pump-faked, pulled out of the grasp of one defender, then threw to Williams. A week earlier, Williams had four drops in the Trojans' 27-20 loss to Kansas State.
Though Anderson struggled, he threw for 1,201 yards and 15 touchdowns during the Beavers' 4-0 start against Eastern Kentucky, Temple, UNLV and Fresno State.
By contrast, the Trojans beat Auburn and Colorado before losing at Kansas State
