Charlie Sitton scored 25 points as Oregon State gave UCLA its first Pacific 10 loss of the season, 69-65, today.

The fifth-ranked Bruins lost their leading scorer, forward Kenny Fields, and 7-foot center Stuart Gray in the first half. Fields suffered a dislocated left shoulder and Gray had partially torn ligaments in his left knee.

Rod Foster scored 17 points for UCLA (17-3, 9-1), which hasn't won at Oregon State since 1979. "The key was to slow them down," Sitton said.

His coach, Ralph Miller, agreed. "Considering we were playing UCLA, this would probably have to be our best effort," Miller said. "We contained their running game and took reasonably good care of the ball."

The Beavers, three-time Pac-10 defending champions, won their fifth in a row and are 12-8 and 6-4.

Miller noted two of his starters were bothered by injuries when the Beavers were beaten, 99-77, at UCLA last month. "Maybe turnabout is fair play," he said.

UCLA took an 11-6 lead, but the Beavers rallied, taking a 29-19 lead on Sitton's 12-foot jumper with 2:42 remaining and holding a 33-27 lead at intermission.

The Bruins rallied in the second half to tie at 39 on Michael Holton's 10-foot jumper with 15:18 to play.

But the Beavers scored the next three baskets, one by Sitton and two by A.C. Green. They went ahead, 69-60, with 59 seconds to play on two free throws by Darryl Flowers.

"I'm proud of how we fought back," said UCLA Coach Larry Farmer. He said Oregon State "played well down the stretch and made every clutch shot and free throw they had to make."
