Los Angeles It's a school-record 23 consecutive victories and counting for Stanford.
The top-ranked Cardinal defeated UCLA, 73-60, Saturday to remain undefeated with two weeks left in the regular season.
Stanford improved to 14-0 in the Pac-10 and clinched its fourth conference title in six years and 11th overall. Rob Little led the Cardinal with 18 points, tying his career high.
"We want to make history," Little said. "Why not go out to win them all? It's a personal goal for everyone now, with four games left, to go undefeated. Why not?"
The Cardinal overcame a 13-point first-half deficit to beat Southern California on Thursday, then won its seventh in a row Saturday at Pauley Pavilion, the only opponent with such a streak in the arena's 39-year history.
"I'm really proud of our guys," Stanford coach Mike Montgomery said. "They came to L.A. to get a sweep to win the conference championship. That's pretty good stuff."
Stanford and No. 2 Saint Joseph's (24-0) are the nation's only undefeated Division One teams. No team since Indiana in 1976 has had a perfect season, and the Hoosiers won the national championship that year.
"It's not a focal point, but the more games we win, the closer it gets," Montgomery said.
Although the Bruins (11-12, 7-8) have lost nine of their last 11 under first-year coach Ben Howland, a win seemed possible based on their history against top-ranked teams.
"We felt we could beat them. We felt good coming in," said Dijon Thompson, who led UCLA with 17 points.
UCLA had defeated a No. 1 team in each of the last four seasons. But other than starting the second half with a big run that cut Stanford's lead to seven points, the Bruins were unable to muster much of a threat.
"It was really a big problem for us to come back," Howland said. "As soon as we had a couple of shots miss, it sped us up instead of slowing down, and you can't do that against a zone."
