Jared Cunningham and Ahmad Starks had 24 points apiece Thursday as Oregon State held off a late California run for a 92-85 win.
Angus Brandt added 14 points and Joe Burton 13 for Oregon State (11-4, 1-2 Pac-12). Jorge Gutierrez had 26 points for Cal (12-4, 2-1).
Oregon State took the lead for good, 40-38, on Cunningham's two free throws 11 seconds after halftime.
A Starks 3-pointer later put the Beavers ahead seven, and Oregon State got the lead to 10 for the first time, 60-50, on two more Cunningham foul shots with 12:23 remaining.
The Beavers went ahead by as many as 16 before Cal scored 12 straight, including two 3-pointers by Allen Crabbe and a four-point play by Gutierrez, to close within 77-73 with five minutes left.
But the Beavers scored the next four and the Golden Bears got no closer than six the rest of the way.
