Justin Cobbs hit a step-back jumper with 0.9 seconds left, and California stunned No. 1 Arizona 60-58 on Saturday night to hand the Wildcats their first loss of the season.

Cobbs dribbled to his left and beat Nick Johnson, then pulled up in front of a defender to sink the winning shot that sent a raucous crowd at Haas Pavilion spilling onto the court. Cal coach Mike Montgomery and security had to usher fans away before the final play.

Gabe York's full-court pass was knocked down to give the Golden Bears (15-7, 6-3 Pac-12) their first victory over a top-ranked opponent since Jan. 30, 1994, when they beat UCLA 85-70 at the Oakland Coliseum.

Arizona (21-1, 8-1) was one of just three unbeaten teams left in Division I. Now only second-ranked Syracuse (21-0), which beat No. 17 Duke 91-89 in overtime Saturday, and No. 4 Wichita State (23-0) remain.
