USC 30, California 9 (final)

USC is 5-1 after defeating California, 30-9, on Thursday night at AT&T Park in San Francisco.

But the future might not be so bright for the Trojans.

Leading rusher Marc Tyler missed all but one play of the second half with what appeared to be an injury to his left arm or wrist.

Marqise Lee, USC’s second-most productive receiver, missed the entire second half –- coming out of the locker room without pads because of an injury that has not been identified.

Without them, the Trojans struggled mightily.

The only thing that saved USC was Cal’s charity.

The Golden Bears coughed up five turnovers, including an interception late in the game that sealed USC’s victory.

Cal quarterback Zach Maynard had three passes intercepted, including two by USC freshman linebacker Dion Bailey. The Golden Bears also lost two of their four fumbles.

Cal has now lost three consecutive Pacific 12 Conference games after opening with three nonconference victories.

And while USC’s record looks pretty good on paper, the Trojans don’t look all that good on the field, meaning they could be in especially big trouble in their next two games -- at Notre Dame on Oct. 22 and at the Coliseum against Stanford on Oct. 29.

Matt Barkley completed 19 of 35 passes for 195 yards with two touchdowns, but was uninspiring. Curtis McNeal led the rushing attack with 86 yards in 17 carries -- mostly after Tyler was injured.

Tyler had 30 yards in 11 carries, and Robert Woods was held to a season-low five catches for 36 yards.

Lee had four catches for 81 yards and a touchdown in the first half. Andre Heidari made field goals of 39, 29 and 23 yards.

For Cal, Maynard completed 25 of 43 passes for 294 yards, but had the three interceptions. His favorite target was Keenan Allen, who had 13 catches for 160 yards.

But Cal had next to no running game, finishing with a net of 35 yards.

Just when it looked like USC's offense would be stagnant for the rest of the game, Cal played give-away again.
