LOS ANGELES (AP) — No. 6 Southern California routed Stanford 56-10 in this century-old rivalry’s final chapter for the foreseeable future. Caleb Williams passed for 281 yards and three touchdowns and ran for another score while playing only the first half, and Zachariah Branch returned a punt 75 yards for a touchdown. The Trojans racked up 433 yards of offense and seven touchdowns by seven players while building a 49-3 halftime lead — the third-largest in Pac-12 history. USC generously used backups in the second half of their blowout of the Cardinal, who lost for the first time under new coach Troy Taylor.
