No. 4 USC is headed back to Pasadena at the very least. The Trojans kept a loftier goal alive as well. QB John David Booty passed for 238 yards and two fourth-quarter touchdowns, the USC defense shut down California in the second half, and the Trojans beat the Golden Bears 23-9 Saturday night to clinch the Pac-10 championship and a berth in the Rose Bowl.
