CORVALLIS, Oregon (Ticker) -- It wasn't pretty, but Stanford was able to remain unbeaten and continue its dominance of Oregon State.
Josh Childress scored 17 points as the second-ranked Cardinal used another stellar defensive effort to extend its winning streak over the Beavers to nine games with a 62-48 Pac-10 Conference victory.
Childress made just 5-of-14 shots but hit a pair of 3-pointers during a 10-0 spurt early in the second half that put Stanford (17-0, 8-0 Pac-10) ahead for good.
Matt Haryasz added 10 points as Stanford overcame a dreadful night by Matt Lottich and improved to 5-0 on the road. The Cardinal have taken 13 of the last 14 meetings in the series, including five in a row at Gill Coliseum.
"We struggled offensively. We didn't shoot the ball very well and didn't execute," Stanford coach Mike Montgomery said. "We defended well collectively and finally got a few guys to turn it around."
Lottich was not one of them. He was just 1-of-12 from the floor and scored four points, 9 1/2 below his average.
Chris Stephens led all scorers with 24 points, but Oregon State (9-6, 4-4) shot under 34 percent (15-of-44) en route to its fourth straight loss.
"They are a great team," Beavers coach Jay John said of the Cardinal. "They are solid and they don't let things ruffle their feathers. They didn't shoot the ball particularly well, but they still were able to combat and execute their defense."
Oregon State led by as many as seven points early, but Childress scored all of his nine first-half points during a 19-6 burst that gave Stanford a 29-23 halftime advantage.
A 3-pointer by Stephens capped Oregon State's 8-0 run to start the second half, but the Cardinal scored the next 12 points on a pair of 3-pointers by Childress and three baskets by Haryasz.
"Winning on the road is still a big deal," Montgomery said. "It's really hard to do, but for us, we're trying to improve. The kids are happy, but I don't think they're overly ecstatic."
