Halftime Analysis: USC 20 - Cal 0 

October, 13, 2011
Key Stat - USC with four turnovers

The Trojans defense recovered two early Cal fumbles to set the tone and added two interceptions. Chris Galippo had an interception deep in Golden Bears territory to set up a score while Dion Bailey got a pick in the end zone at the end of the half after the best Cal drive of the night. The Trojans were able to capitalize enough to help build a 20-0 halftime lead thanks in part to a Cal offense that didn't get much going until that late 2nd-quarter drive.

Turning point - Marqise Lee touchdown
