LOS ANGELES — Matt Barkley passed for 233 yards after a slow start to his Southern California debut, and the No. 4 Trojans' fleet of tailbacks ran for six touchdowns in a 56-3 victory over San Jose State on Saturday.

Barkley, the first non-redshirt freshman to start a season opener at USC, shook off a rocky first quarter to go 15 for 19 with no interceptions.

He was at his best handing off to his fellow Trojans, who pounded the Spartans with six consecutive TD drives after trailing 3-0 early in the second quarter.

USC's formidable offensive line cleared the way for 343 yards rushing, along with two scores apiece by Stafon Johnson and Joe McKnight. Barkley's only TD pass put USC up 42-3 midway through the third quarter.
