SOUTH BEND, Ind. — Southern California handed Notre Dame a beating for theages.

Mark Sanchez threw four touchdown passes — two on short drives after miscuesby the Fighting Irish — and No. 13 USC beat the Fighting Irish 38-0 Saturday,the largest margin of victory for the Trojans’ in the 79-game history of thestories rivalry.

Notre Dame can still claim the most-lopsided victory in the history of theseries, a 51-0 win over the Trojans in 1966.

USC (6-1), coming off three lackluster games — including a stunning 24-23loss to Stanford — started slowly, but got rolling when a punt by Notre Dame’sGeoff Price struck teammate Munir Prince and USC’s Vincent Joseph recovered atthe Irish 10. The Trojans scored on the next play on a pass from Sanchez to FredDavis.

The Irish played as ugly as they looked in their throwback green jerseys andyellow pants, dropping to 1-7 for just the second time, matching the 1960 start.

The loss ensures Notre Dame its 13th losing season since it started playingfootball in 1887, and its fourth losing season since 1999. It also is the fourthstraight home loss, tying a school record.

The game was competitive for a while.

The Trojans went ahead17-0 with 11 seconds left in the half on a 30-yard field goal by David Buehler.

USC quickly turned it into a blowout in the second half after Travis Thomasfumbled on the Notre Dame 13. Sanchez threw a 5-yard scoring pass to StanleyHavili.

Vidal Hazelton scored a 48-yard touchdown, catching the pass from Sanchez atthe 30-yard line and breaking three tackles en route to the end zone. JoeMcKnight scored on a 51-yard run in the fourth quarter.
