LOS ANGELES — Southern California coach Steve Sarkisian didn’t bring any players with him to his postgame press conference, choosing to be the face of the Trojans’ fourth loss as a double-digit favorite in less than two seasons as head coach.

“This one, at the end of the day, is on me,” he said.

Myles Gaskin ran for 134 yards and a fourth-quarter touchdown, and Washington shut down No. 17 USC’s high-powered offense throughout a 17-12 victory Thursday night.

“We didn’t coach well enough, we didn’t execute well enough, we didn’t manage the game well enough and ultimately execute in the critical moments well enough to deserve to win the football game,” Sarkisian said.

The frustrated crowd of 63,623 that battled notorious freeway traffic only to see USC’s offense held under wraps, its defense buckle in the fourth quarter, and a host of questionable coaching decisions would not disagree.

Receiver Marvin Hall threw a 27-yard touchdown pass to Joshua Perkins early in the second half as the Huskies (3-2, 1-1 Pac-12) beat the coaches who recruited many of them to Seattle. They all celebrated with their strong cheering section after running out the clock on Washington’s first win at the Coliseum since 2010.
