TEMPE, Ariz. -- Will Harris returned an interception 55 yards for a score, Matt Barkley threw a 75-yard pass to Damian Williams for another score, and No. 12 USC held on for a shaky 14-9 victory over Arizona State on Saturday night.

Coming off the worst loss in the Pete Carroll era, the Trojans (7-2, 4-2 Pac-10) barely survived on a night they produced little on offense. The victory kept the Trojans in the hunt for an eighth straight Bowl Championship Series berth.

USC's defense was the reason the Trojans beat ASU (4-5, 2-4) for the 10th straight time.

Sun Devils freshman Brock Osweiler came off the bench and threw a 23-yard touchdown pass to Chris McGaha. But Harris ended ASU's upset bid by picking off Osweiler's last-gasp pass in the end zone as time expired.
