Halftime: Cal 17, Arizona State 14

Posted by ESPN.com's Ted Miller

California can't feel too good about being up only 17-14 over Arizona State at the break.

The Bears have piled up 218 yards and 15 first downs but have allowed the Sun Devils to hang around because of two mistakes.

The Sun Devils' first touchdown drive went just 3 yards after a Kevin Riley fumble, his second in Bears territory in the half. Their second went 80 yards on one play, a bomb from Danny Sullivan to a wide-open Kyle Williams.

Other than that, Arizona State had 92 yards in the first half.

Meanwhile, the Bears had a pair of 67-yard TD drives, which both ended with Riley touchdown passes.

Riley, despite the fumbles, continues to look sharp passing since his bad efforts vs. Oregon and USC. He's 15-of-23 for 182 yards at the half.

By the way, both Riley fumbles came on sacks by defensive tackle Lawrence Guy. Here's some advice to Cal: Block Guy.

Four first-half turnovers -- two apiece.

Will there be a mistake imbalance in the second half? It seems like Cal could take care of business if it gets out of its own way.
