LOS ANGELES — Justin Cobbs scored 18 points and California withstood UCLA's late rally to win 73-63 Saturday, moving the Golden Bears into sole possession of first in the Pac-12 with their 20th victory of the season.

Allen Crabbe added 14 and Jorge Gutierrez 13 for the Bears (20-6, 10-3), who shot 52 percent from the floor in completing their first season sweep of the Bruins since 1993-94. The Bears beat USC 75-49 on Thursday night and have won all four regular-season games against the L.A. schools for the first time since 1958-59.

The Bears had been tied for first in the league with Washington, which plays at Oregon State on Sunday. Cal earned its third 20-win season under coach Mike Montgomery.

Jerime Anderson scored 16 points, Lazeric Jones 15 and David Wear 11 for the Bruins (14-11, 7-6), who lost at home for the first time in six games.

At Arizona 70, Utah 61

Nick Johnson hit a three-pointer with just over a minute left and had 18 points, Kyle Fogg added 17 points, and Arizona overcame an ugly first half to beat Utah.

Coming off three solid wins, Arizona (18-8, 9-4) came out flat against Utah, falling into a 13-point first-half hole.

The Wildcats rallied in the second half behind the three-point shooting of Fogg and Brendon Lavender, then held on after Johnson's three-pointer to win their fourth straight game. Solomon Hill had 14 points and Lavender hit four three-pointers for all of his 12 points.

Utah (5-11, 2-11) hit 9 of 18 from behind the arc against the Pac-12's best team at defending three-pointers, but didn't hit a shot from anywhere over the final 5:42 to lose its sixth straight game. Jason Washburn and Cedric Martin had 15 points each for the Utes, 0-13 on the road this season.

Colorado 63, at Arizona State 49

Spencer Dinwiddie scored all 15 points in the second half as Colorado routed Arizona State.

Andre Roberson and Austin Dufault added 12 points apiece for the Buffaloes (17-8, 9-4), who won their third straight game against the Sun Devils (8-17, 4-9) and have won three of four overall.

Jonathan Gilling scored 11 points and Trent Lockett added 10 for Arizona State, which has lost three of four and eight of its past 11.

Gilling hit a three-pointer and Ruslan Pateev added a layup as the Sun Devils trimmed a seven-point halftime deficit to 31-26 with 17:34 remaining.

But Dinwiddie hit the second of his three three-pointers and Nate Tomlinson added a three-pointer to spark an 8-0 run that gave Colorado a 39-26 lead with 14:45 remaining. The Buffaloes led by as many as 19 in the second half.
