Harper Kamp scored on a baseline layup with 49.7 seconds left, Allen Crabbe made three late free throws and California overcame one of its worst offensive performances of the season to beat Colorado 57-50 on Thursday night at Berkeley, Calif.

Kamp finished with 14 points and eight rebounds and Justin Cobbs added 12 points and five rebounds to help the Golden Bears (14-4, 4-1) move into a tie for the Pac-12 lead with Bay Area rival Stanford.

California did it despite an off night from its two leading scorers, Crabbe and Jorge Gutierrez, who went a combined 4 of 26 from the floor.

Andre Roberson had 11 points and 14 rebounds for Colorado (11-5, 3-1), which had won six straight overall before suffering its first Pac-12 loss.

Arizona 81, Oregon State 73 (OT): Kyle Fogg had 23 points and scored on a hard drive in overtime that nearly set off a brawl, lifting the Wildcats (11-6, 1-4) to a win over the Beavers (12-5, 3-1) at Tucson, Ariz.

Oregon State forced overtime after Ahmad Starks scored 10 of his 14 points in the final 3:16 of regulation. Arizona took control in overtime, going up six after a rebound slam by Nick Johnson and Fogg’s drive with 1:15 left.

Fogg ran into Oregon State’s Jared Cunningham while celebrating the basket, setting off a near melee that had players from both teams pushing each other and Wildcats coach Sean Miller shoving his players back to the bench.

Oregon 67, Arizona State 58: Devoe Joseph scored 15 points to lead four Oregon players in double figures, and the Ducks (12-5, 3-2) used a surge midway through the second half to beat the Sun Devils (5-11, 1-3) at Tempe, Ariz.
