CORVALLIS, Ore. - Justin Cobbs had 18 points and surging California won its fifth straight game by outlasting a late rally from Oregon State for a 60-59 victory on Saturday.
California (18-9, 10-5 Pac-12) has won seven of its last eight games, including victories over then-No. 7 Arizona and No. 23 Oregon.
The Golden Bears are suddenly sneaking up the Pac-12 rankings, joining Arizona, Oregon and UCLA, and positioning themselves for a possible NCAA tournament berth with three games left.
The Golden Bears led by as many as 14 points, but Oregon State cut it to 45-42 on Joe Burton's layup with 8:32 left in the game. The Beavers (13-15, 3-12) stayed within reach and Devon Collier's layup cut Cal's lead to 58-55 with 1:47 left.
Cobbs hit a jumper from atop the key for California before Collier made four straight free throws to pull within 60-59 with 43 seconds left.
With 10 seconds left, Cobbs missed a jumper out front. But Ahmad Starks' 3-point attempt missed with a second left on the clock to end it.
Burton, a senior playing his last game at Gill Coliseum, had 15 points, nine rebounds and seven assists.
The Golden Bears were coming off a 48-46 victory over the Ducks in Eugene on Thursday. Cobbs' jumper with less than a second to play won it for Cal.
The Beavers were coming off an 82-72 loss to Stanford on Thursday. Oregon State has lost three straight.
