Sean Mannion passed for a career-high 379 yards and two touchdowns, Oregon State put the clamps on No. 19 UCLA's offense, and the unbeaten Beavers opened their Pacific-12 Conference season by stunning the Bruins 27-20 Saturday.
The victory was the 74th at Oregon State for coach Mike Riley, matching the school record set by Lon Stiner, the Beavers' coach from 1933 to 1948. Riley is in his 12th year with Oregon State.
Mannion, a third-year sophomore, completed 24 of 35 passes with one interception and has passed for 200 or more yards in 13 straight games.
Oregon State's Markus Wheaton had nine receptions for 150 yards and has caught at least one pass in 25 consecutive games. Brandin Cooks had six catches for 175 yards, and Storm Woods rushed for 96 yards on 21 carries for the Beavers.
The Bruins (3-1, 0-1 Pac-12) scored 15 touchdowns and averaged 622.0 yards to rank second nationally in total offense in their previous three games. But the Beavers (2-0, 1-0) held them to 444 yards and two TDs.
Oregon State had played just once in the season's first three weeks, beating then-No. 13 Wisconsin 10-7 on Sept. 8. The season opener against Nicholls State was postponed because of concerns over Hurricane Isaac.
UCLA's Johnathan Franklin, the country's leading rusher with a 180.3-yard average, was held to 45 yards on 12 carries. He averaged 8.2 yards per carry previously this year. Redshirt freshman Brett Hundley completed 27 of 42 passes for 372 yards and a touchdown.
Trailing 17-10, the Bruins blew two scoring chances in the third quarter. First, they failed to convert a fourth-and-2 at the Oregon State 35-yard line after Anthony Barr forced a fumble by Mannion at the Beavers 43 and Tevin McDonald recovered.
The Bruins got another chance when Stan McKay intercepted Mannion's pass at the Beavers 48 on the next play, but they were forced to punt.
The Beavers then moved 88 yards on 13 plays to take a 24-10 lead, scoring on a 2-yard run by Storm Woods one play after a pass interference penalty against Sheldon Price on third-and-goal.
UCLA responded by getting a 1-yard sneak from Hundley that capped a 75-yard drive and made it 24-17 with 14:01 to play.
NO. 13 USC 27,
Matt Barkley passed for 192 yards and threw two touchdown passes to Marqise Lee, and Southern California bounced back from its first defeat with a 27-9 victory over California on Saturday.
Lee had 11 catches for 94 yards, and Silas Redd rushed for 158 yards and a score as the Trojans (3-1, 1-1 Pac-12) grinded out their ninth consecutive win against the Golden Bears (1-3, 0-1) in the schools' 100th meeting.
A week after the preseason No. 1 team got shut out in the second half of a 21-14 loss at Stanford, USC drained the suspense from this matchup with a methodical 75-yard drive that consumed more than half of the fourth quarter, capped by Lee's 3-yard TD catch with 5:56 to play.
Keenan Allen had nine catches for 94 yards for the Bears, who couldn't get into the Coliseum end zone and managed only 250 total yards.
