BOULDER, Colo. - Ben Howland has seen enough close calls the past three days to last a season.

He watched Utah's Glen Dean miss a potential game-tying three-pointer in Salt Lake City on Thursday and had to grimly watch another near miss Saturday, this time by Askia Booker at Colorado.

"Utah ran the same play to Dean," said the UCLA coach. "So when Colorado had a three to tie the game, my heart was halfway down my stomach on that last shot by Booker."

But Booker missed, giving the Bruins their ninth straight victory, 78-75. Travis Wear scored 14 of his career-high 23 points in the second half and Jordan Adams' two free throws with 7 seconds left provided the three-point cushion.

Adams finished with 18 points for UCLA (14-3, 4-0 Pac-12). Shabazz Muhammad added 14 and Kyle Anderson 12 for the Bruins, whose winning streak is their longest since a 10-game streak in 2008-09.

"This is a great win over a very good team," Howland said. "I told our team today before the game that this is a sixth-ranked team in RPI and this is obviously a hard place to win."

UCLA, coming off a season-low 57-point scoring output, improved to 6-1 all-time against the Buffaloes.

Spencer Dinwiddie led Colorado (11-5, 1-3) with 23 points. Josh Scott and Booker had 18 each for the Buffaloes, losers of three of their last four.

"We played with too much inconsistency, and I am disappointed with that," said Colorado coach Tad Boyle. "Fourteen turnovers are too many to defeat a good team."

The Buffaloes gave up 17 points off turnovers. And they allowed UCLA to gain an additional 17 points with its fast break.

"The transition points," said Boyle, shaking his head. "We had made a goal of minimizing transition points."

After a sluggish first half, UCLA took a 42-37 lead on Wear's short jumper. Booker tied it at 42 with a three-pointer.

Wear answered with another jumper that started a 14-2 run, capped by a three-pointer and free throw by Adams, that pushed UCLA's lead to 58-45. Norman Powell kept it a 13-point edge with his own trey with 8:03 left, but Booker made two free throws to get Colorado back to 72-68.

• California 67, Washington State 54: In Berkeley, Calif., Tyrone Wallace scored a season-high 16 points, Justin Cobbs made six free throws in the final two minutes and California overcame a sloppy offensive performance to win.

Allen Crabbe added 14 points. Cobbs finished with 10 points, five assists and five rebounds for the Golden Bears (10-6, 2-2 Pac-12), who won for just the fourth time in 10 games after opening the season 6-0.

California was held without a basket over the final 4:59 but went 11 of 12 at the free-throw line down the stretch to hold off Washington State (9-7, 0-3).

• USC 76, Utah 59: In Salt Lake City, J.T. Terrell scored 14 points and USC won to snap a string of 14 straight road losses.

Dewayne Dedmon had 13 points, 13 rebounds and five blocks for the Trojans (7-10, 2-2), while Jio Fontan and Byron Wesley scored 13 points each.

The Utes (8-8, 0-4) were within 50-42 on Jarred DuBois' three-pointer with 10:26 remaining, but USC answered with a 7-0 run.
