Brock Mansion started in Riley's place and had a palatable game. He completed 12-of-24 passes for 174 yards, but he did toss two interceptions against a poor Cougar defense that ranks in the bottom of the conference.
Luckily, the Golden Bear defense didn't have its usual defensive lapse on the road holding WSU to only 194 yards of total offense. The Cougars have now lost 16 consecutive conference games.
However, Washington State managed a 10-7 lead at halftime, their first halftime lead in a Pac-10 game since 2007.
Cal responded with wide receiver Jeremy Ross taking a fly sweep 27 yards for a touchdown less than four minutes into the third quarter to take a 14-13 lead it wouldn't relinquish.
An Andrew Furney field goal cut the Cal lead to 14-13 later in the third quarter. The Bears answered in the fourth with a 10-play, 65-yard scoring drive capped by Shane Vereen's second touchdown run of the game. Vereen finished with 112 yards rushing.
Marvin Jones caught four passes for 101 yards.
