EUGENE, Ore. - Justin Cobbs' jumper with 0.7 seconds to play gave California a 48-46 victory over No. 23 Oregon on Thursday night.
Cobbs' shot, which came after the Golden Bears (17-9, 9-5 Pac-12) ran nearly all of the final 26 seconds off the clock, hit nothing but net.
Oregon (21-6, 10-4) is tied with Arizona for the Pac-12 lead, while Cal continued its climb with its sixth win in seven games.
Cobbs finished with 14 points and Allen Crabbe had 12 for Cal, which has won four straight.
Arsalan Kazemi had 11 points and a season-high 18 rebounds for the Ducks, who lost their 11th straight game to the Bears. Carlos Emory scored 13 points for Oregon, which hasn't beaten Cal since Feb. 9, 2008.
Oregon, which led 26-21 at halftime, was up 46-43 with 2:06 to play when Robert Thurman recorded a three-point play for Cal on a dunk and free throw to tie it.
The Ducks had a turnover and two missed shots in their final possessions.
Cal trailed by 11 points in the first half but came back to tie the score at 29 on a dunk by Thurman 4 minutes into the second half.
Oregon went back up 37-33 on a free throw and three-pointer by E.J. Singler, but the Bears followed with a 6-0 run and Cobbs hit a jumper to put them up 39-37 with 7:12 to play. It was Cal's first lead since early in the first half.
Trailing 41-39, Oregon followed with five straight points to take a 44-41 advantage with 3:30 to play, setting the stage for Cal's final heroics.
