BERKELEY — 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, gold-shirt wearing 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 after the timeout 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), which had won a school-record 21 straight games, was one of just three unbeaten teams left in Division I. Now only second-ranked Syracuse (21-0), which outlasted No. 17 Duke 91-89 in overtime Saturday, and No. 4 Wichita State (23-0) remain.
Cobbs finished with 19 points and seven assists, David Kravish had 14 points and 11 rebounds and Richard Solomon scored 12 points to propel Cal to one of the biggest wins in school history. The Bears improved to 3-24 against teams ranked No. 1 in The Associated Press poll, and they had never beaten a top-ranked team in Berkeley.
Kaleb Tarczewski scored a career-high 18 points and grabbed six rebounds, and T.J. McConnell scored 13 points for the Wildcats, who shot just 32.3 percent from the floor. Cal shot 44.6 percent.
Cal attracted quite an audience for this one, too.
There were 21 scouts from 14 different NBA teams in attendance. Former Wildcats coach Lute Olson sat in the stands behind Arizona's bench, and Oakland Athletics manager Bob Melvin — a Cal alum — also supported his Bears.
The Wildcats rallied from nine points down in the first half and eight in the second to set up a furious finish.
at Stanford 76, Arizona State 70: Dwight Powell matched his season high with 28 points to help the Cardinal (14-7, 5-4) prevail.
Jahii Carson scored 24 points to lead the Sun Devils (16-6, 5-4), who had their winning streak ended at three games. Jermaine Marshall had 22 points.
Arizona State’s Jordan Bachynski blocked two shots and has 91 this season.
He needs six to match former Arizona star Anthony Cook for the all-time Pac-12 lead. Cook had 278.
at Colorado 79, Utah 75 (OT): Xavier Talton scored five points in overtime, including a go-ahead three-point basket to lead the Buffaloes (16-6, 5-4).
