COLUMBUS, Ohio (AP) - Backed up to their own goal line, Matt Barkley and Joe McKnight drove into Southern California lore. Barkley, the freshman quarterback, and McKnight, the shifty tailback, made big play after big play, and Stafon Johnson capped one of the great drives in USC's storied history with a 2-yard touchdown run with 1:05 left to give the third-ranked Trojans a 18-15 victory against No. 8 Ohio State on Saturday night.

For the Buckeyes (1-1), it was another big-game heartbreaker, maybe the toughest one yet. Ohio State has lost six straight against top-five teams.

For the Trojans, it was their 10th straight victory against a Big Ten team. None was tougher ¬- and none was likely more satisfying for Pete Carroll's team.
