The win, the Golden Bears' third in four games, makes them bowl eligible after sitting out the postseason last year. It also snapped Cal's four-game losing streak to the Beavers.
Backup running back C.J. Anderson ran for 96 yards and wide receiver Michael Calvin, a fifth-year senior, caught his first career touchdown for the Bears, who overcame a season-high 15 penalties in their final game at AT&T Park. Cal (6-4, 3-4 Pac-12) will move back home to Memorial Stadium, which underwent a $321 million facelift, for the 2012 season.
Sean Mannion passed for 247 yards for Oregon State (2-8, 2-5), but the Beavers turned the ball over twice inside the 5-yard line.
