LOS ANGELES -- Not even the momentum of a three-game win streak could get Stanford over the hump Thursday night in a city where it has forgotten how to win.

UCLA's 91-74 victory was its ninth in a row over the Cardinal at Pauley Pavilion.

Stanford (12-6, 3-3), which plays Sunday at USC, has lost 16 of its past 17 road games against the Pac-12 Conference's two Los Angeles teams.

"It's been tough," said coach Johnny Dawkins, yet to win a Pac-12 regular-season game in Los Angeles in six seasons. "Very tough on the road wherever you go."

The Bruins (15-4, 4-2) used a 19-3 first-half run to take charge and never let Stanford to get closer than 10 points the rest of the way. UCLA moved into sole possession of third place and goes after second-place Cal here Sunday.

Stanford struggled most of the evening to crack UCLA's defense, relying primarily on 3-point shooting.

Guard Chasson Randle, who scored 33 points last Saturday against Washington, didn't make his first basket until just 4:15 remained in the game. Randle finished with 14 points but shot 3 for 16 from the field.

"You're going to have nights like that," said Randle, who shot 11 for 15 against Washington. "All you can do is live with them and do something else on the court."

Dwight Powell had 17 points and 13 rebounds, and Josh Huestis added 12 points and 12 rebounds.

But the Cardinal shot just 38.6 percent from the field, was outscored 46-12 in the paint and committed 19 turnovers, leading to 22-1 disparity in points off turnovers.

Turnovers have not been a problem for the Cardinal, which had just seven in its previous game and averaged fewer than nine in Pac-12 play. But the Bruins feasted on Stanford's giveaways.

"They've got long, athletic players with quick hands," Powell said. "They're a very good defensive team."

"They did a really good job of clogging the lane," Randle said. "We weren't being careful in how we were passing it in there."

UCLA found an unlikely power source in sophomore forward Tony Parker, who came off the bench to score a career-high 22 points. Point guard Kyle Anderson contributed 13 points, seven rebounds and 10 assists, and Jordan Adams scored 19 points.

Down 11 at halftime, Stanford did not make a basket in the second half until Powell converted from the lane with 14:21 remaining. By then, UCLA had stretched its lead to 15 points.

The first half featured 14 lead changes before the Bruins took charge with a 19-3 run that spanned just over 7 minutes and led to a 42-31 halftime edge.

Stanford was up 23-21 after a 3-pointer by John Gage with 9:31 left when things suddenly changed.

The Cardinal shot 1 for 9 and had four turnovers during its next 11 possessions, and the Bruins zoomed away. Only a 3-point basket by Randle -- Stanford's fifth 3-pointer of the half -- prevented a seven-minute whitewash.

Seven UCLA players scored during the surge, with reserves contributing eight points. Adams, mired in a shooting slump the previous four games, hit a 3-pointer then a layup off a feed from Anderson to cap the run and give UCLA a 40-26 lead with 2:28 left in the half.

"Turnovers," Dawkins lamented. "We didn't score, but we weren't stopping them at that point. They had momentum."

And they kept it.
