SEATTLE — Southern California was leveled by another post-Ohio State funk, taken down by upstart Washington with a late drive that must have looked familiar to the Trojans.

Erik Folk kicked a 22-yard field goal with 3 seconds remaining and Washington's fired-up defense stymied fill-in quarterback Aaron Corp and No. 3 USC in a 16-13 victory today.

USC quarterback Matt Barkley, who directed an epic game-winning drive to beat the Buckeyes in Columbus, Ohio, last week, could only watch the latest stunning upset loss by the Trojans from the sideline. The star freshman was out with a sore shoulder.

It's the second consecutive season the Trojans have lost their Pac-10 opener days after an impressive win over Ohio State and it marks the fourth straight season USC has lost to an unranked team.

This one will gnaw at USC coach Pete Carroll. Washington (2-1, 1-0) had lost a Pac-10 record 15 straight games. Now Washington coach, and former Trojans offensive coordinator, Steve Sarkisian has a victory that will go down in Huskies history just three games into his career in Seattle.

"Our kids played very hard. I don't know if we played very good, but we played hard," Sarkisian said. "It's unbelievable. It's what we were hoping for. We're trying hard."

Corp, a redshirt sophomore making his first career start, was 13 for 22 for 110 yards with one interception. USC (2-1, 0-1) was held to its lowest point total since a 13-9 loss to UCLA on Dec. 2, 2006.

The Trojans were also without All-American safety Taylor Mays, who missed his first career game because of the right knee ligament he sprained against the Buckeyes.

Joe McKnight, who finished with 100 yards on 11 carries with a touchdown, took off on a 34-yard run — and split end David Ausberry recovered his fumble at the end of the sprint — to get USC to the Huskies 22 while down 13-10 with 6 minutes left. But Donald Butler, who was all over the field for Washington, stopped Stafon Johnson on third-and-6. That forced the Trojans to settle for a 25-yard field goal from Jordan Congdon that tied it at 13 with 4 minutes remaining.

The USC offensive players angrily yanked their chin straps for not taking the lead after that series.

Washington faced a third-and-15 with 3:03 left, but Locker connected with Jermaine Kearse for 21 yards. Locker then rolled out for 4 yards to convert another third down to the USC 39 with a minute left.

Locker then avoided a rush, and fired 19 yards to Kearse, to the USC 16. Locker and Kearse shared a leaping chest bump, old Husky Stadium swayed, and a roughing-the-passer penalty put the Huskies at the 8 with 33 seconds left.

One running play later, Washington called time out with 7 seconds left to put Folk in position. The sophomore from Woodland Hills, Calif., nailed it down the middle — and the Huskies' bench erupted in a scene that instantly erased years of futility.

USC tried multiple laterals on the final play, the kickoff, but couldn't get out of its own end. Kick returner Johnson was face down in the middle of the turf as jubilant Washington players and fans swarmed out of the stands to celebrate their Huskies' first win over USC since 2001, Carroll's first season with the Trojans.
