PASADENA, Calif. (AP) - A dominating victory by UCLA ended Oregon State's four-game winning streak and put the Beavers' bowl hopes on hold.

The Beavers (6-4, 4-3 Pacific-10 ) were on a roll heading into Saturday's 25-7 loss to UCLA (5-5, 3-4 Pac-10). After a 33-31 upset of USC on Oct. 28, Oregon State players had talked of winning out. California's 24-20 loss at Arizona Saturday had made the Pac-10 race more interesting.

But problems plagued the Beavers against the Bruins.

Oregon State's Matt Moore, who transferred from UCLA after losing the starting job in 2003, was sacked five times - including twice in the fourth quarter. He was 16-of-28 for 159 yards and no touchdowns.

"They're a good football team, but we didn't play to our ability today,'' Moore said. "It hurts. They beat us, and we beat ourselves as well. We didn't execute.''

Yvenson Bernard scored up the middle for the Beavers' lone touchdown in the second quarter. He was their leading rusher with 16 carries for 54 yards and leading receiver with five catches for 41 yards.

UCLA's Justin Medlock, who came into the game tied for the NCAA lead with 19 field goals, made kicks of 40 and 42 yards in the second quarter, when the Bruins trailed 7-6. He added two more in the fourth, extending the lead to 25-7.

The victory ended UCLA's four-game losing streak.

UCLA stopped Oregon State's first drive of the third quarter when Bernard was tackled for a 3-yard loss on fourth down.

Oregon State's Alexis Serna, the fourth-best kicker in the nation, missed a 30-yard field goal wide left. On their next possession, the Beavers committed the third of their four fumbles in the game.

Bernard tweaked his ankle midway through the third quarter and played only briefly in the fourth. He described the injury as minor.

In the fourth quarter, Marcus Everett caught an 11-yard TD pass from Patrick Cowan for a 19-7 lead. The 2-point conversion failed when Cowan's pass was incomplete to Logan Paulsen.

Cowan was 12-of-23 for 126 yards and two touchdowns.

Everett caught three passes for 64 yards and both touchdowns.

"That was a terribly disappointing game. We've been on a good run and have been playing some good football,'' Beavers coach Mike Riley said. "We just turned the ball over too many times to win. I'm surprised, disappointed and anxious to get ready for the next game. I think that we can bounce back and play better.''

Next up for the Beavers is Stanford, which won its first game of the season Saturday, 20-3 over Washington.
