LOS ANGELES (Ticker) -- Oregon State's quest for its first 5-0 start in 63 years ran into its usual roadblock at the Los Angeles Coliseum.
Carson Palmer threw two touchdown passes to freshman Mike Williams and 22nd-ranked USC shut down Oregon State's normally high-powered offense in a 22-0 victory over the 24th-ranked Beavers in the Pac-10 Conference opener for both teams.
Sophomore Ryan Killeen kicked field goals of 43, 42 and 32 yards for the Trojans (3-1, 1-0 Pac-10), who posted their 19th straight home win over the Beavers since their last loss in 1960. Killeen, who also missed a 40-yard attempt, took over as the primary kicker in place of the ineffective David Davis and recorded the first three field goals of his career.
Taking advantage of a favorable early schedule, Oregon State (4-1, 0-1) scored 190 points in its first four games and was seeking it first 5-0 start since 1939. But the Beavers could get nothing going against USC, suffering their first shutout loss since a 23-0 setback to the Trojans in 1997.
"USC kicked our rear ends in a lot of phases," Oregon State coach Dennis Erickson said. "I've never had an offense that was so inefficient as we were today. Give their defense credit. It was ugly. Our defense played well, but they were on the field the whole game."
The Trojans recorded their second shutout in six games after blanking UCLA, 27-0, in their final regular season game in 2001. USC also bounced back admirably from a close loss at Kansas State last week.
"I'm thinking that we are going to be a good ballclub," USC coach Pete Carroll said. "We know we can play defense and if we can keep taking care of the ball on offense, we are going to be tough to beat."
Killeen kicked his first field goal on the second play of the second quarter. Derek Anderson was sacked and fumbled on the Beavers' next possession, leading to another field goal by Killeen.
Palmer completed an 11-yard TD pass to Williams with 10 seconds left in the second quarter, giving the Trojans a 13-0 halftime lead. The 60-yard drive began after Anderson was sacked and fumbled at Oregon State 40.
Palmer completed 23-of-41 passes for 231 yards with one interception. He completed passes to seven different receivers with Keary Colbert catching six balls for 67 yards.
"I don't think we played well. I don't think I played well," Palmer said. "The defense won the game today."
Williams caught a 16-yard TD pass from Palmer late in the third quarter and Killeen kicked his final field goal early in the final quarter.
Anderson threw 15 TD passes in his first four games, but was just 8-of-30 for 80 yards and was sacked five times.
"Yeah, I'm pretty sore. They came after me hard all day," Anderson said. "Sometimes it was me holding the ball too long and sometimes it was missed blocking assignments."
Tailback Steven Jackson, who ran for 227 yards last week against Fresno State, was held to 67 yards on 15 carries.
USC managed just 99 yards on the ground with Sultan McCullough gaining 50 yards on 19 carries.
