LOS ANGELES — For UCLA, it was a home finale worthy of their Hollywood locale.

Stanford peskily hung with the quicker Bruins through the first 20-plus minutes, but UCLA used a 10-0 run in the early second to pull away for a 75-61 victory.

“[UCLA] got a little momentum after getting those fast-break points,” sophomore forward Lawrence Hill said. “Other than that, I’d say we were pretty even up to the second half.”

Aaron Afflalo scored 20 points as UCLA (25-3, 14-2 Pacific-10 Conference) clinched a share of the Pac-10 title with their 20th straight victory at Pauley Pavilion. Despite freshman Brook Lopez’s third-straight game with over 20 points (23 points, 11-of-16 shooting, nine rebounds), Stanford’s (17-10, 9-7) margin for error greatly shrunk in its quest for the NCAA Tournament.

“Every loss makes our future harder,” Hill said.

A jumper from Darren Collison, who coach Trent Johnson called one of the best point guards in the country, kick-started UCLA’s run. Then came a three and a fast-break dunk from Luc Richard Mbah a Moute (11 points), who ate up Stanford’s post defense alongside teammate Lorenzo Mata (eight points).

“I let Luc get a couple of easy shots,” Brook Lopez said. “He attacked the basket and just finished around me.”

A three from a wide-open Russell Westbrook capped the 4:27 spurt. UCLA led 53-40 with under 13 minutes to go and Stanford would pull no closer than nine for the rest of the way.

“The turnovers were where they scored baskets,” said Trent Johnson, whose team turned it over 16 times on the afternoon, three times during UCLA’s run. “Where they got their momentum is what they’ve been doing all year, going the other way and creating steals.”

The Cardinal never led the contest, but trailed by no more than six for the first 25 minutes. Hill’s three pulled Stanford within three (36-33) at halftime, and another Hill three and a jumper from redshirt junior forward Fred Washington tightened the score to 43-40 with 16:54 to go.

UCLA used its speed advantage to repeatedly force turnovers and find open looks off fast breaks and screens. Still, Brook Lopez matched the Bruins with key basket after key basket, and the Cardinal looked able to become the first visiting team to win at Pauley since West Virginia did in January 2006.

“This Brook Lopez is something special,” UCLA coach Ben Howland said. “He will be in the NBA at some point.”

While Trent Johnson expressed utter disappointment in his team’s play after Thursday’s 69-65 loss at Southern California, he was decidedly upbeat post-game Saturday. He mentioned several times the impact of injured sophomore guard Anthony Goods’ absence, and implied that with a healthy Goods, the Cardinal might just have won.

“The biggest factor was not having an additional scoring option,” said Johnson, noting UCLA’s 70-65 loss at West Virginia with an injured Collison out two weeks ago. “A guy like Anthony’s hard to replace. He realizes what he could do and what he could mean for his team in games like this.”

Brook Lopez agreed that Goods is crucial to the team.

“There’s obviously a big emotional shot; having Anthony Goods, that starts our rush all the way around, and we’re missing that,” he said.

After suffering a high ankle sprain two weeks ago at Washington, Goods was again evaluated yesterday. Coach Johnson refused to lay down a timetable for Stanford’s No. 2 scorer, but expressed guarded optimism.

“Regardless of what any doctor says, or how he feels, I’m not going to put any kid out there at this time of year and let him reinjure himself,” Johnson said. “So we’ve got to take a look; but for the most part, he looks good, and I was encouraged by what he looked like the other day.”

Meanwhile, for UCLA’s star-scorer Afflalo, the game likely marked his last at Pauley. Fans chanted “One more year!” postgame, imploring the junior to bypass the NBA and return to Westwood, but one does not need a Ph.D. in psychology to read through his noncommittal answer: He’s all but gone.

“I haven’t put too much thought into it,” Afflalo said about declaring for the NBA. “That’s just a question you have to answer in due time. Again, I’m just enjoying the now.”

Kareem Abdul-Jabbar, and 96-year-old John Wooden, respectively among the best players and coaches in basketball history, were honored at halftime alongside the rest of UCLA’s 1967 national title team.

After the weekend sweep, Stanford’s RPI (computer ranking) stands at 41, and Web sites project the Cardinal anywhere from a seven to a 10 seed in the NCAA Tournament. With a sweep of the Arizona schools this weekend, Stanford looks safe, and even just with a win against bottom-feeder Arizona State this Thursday, the Cardinal look to be in decent shape.

Meanwhile, with the nation’s top RPI, UCLA looks a safe bet for a No. 1 seed, provided they handle a visit to Washington State this week and the Pac-10 Tournament the week after.
