No. 8 Stanford 20, Oregon State 12: Tyler Gaffney rushed for 145 yards and three touchdowns as the visiting Cardinal held off Sean Mannion, Brandin Cooks and the high-powered Beavers' passing attack.

Stanford (7-1, 5-1 Pac-12) held Mannion to 271 yards - 88 in the first half - on 41-of-57 passing with a touchdown to Cooks and sacked him eight times.

The Beavers advanced to the Cardinal 7 before Mannion threw four consecutive incomplete passes into the end zone - the last intended for Kevin Cummings and broken up by Ed Reynolds.

Gaffney put Stanford ahead for good in the opening period when he bounced off the line, regained his balance and found a clear path to the end zone for a 4-yard score. After Joe Hemschoot recovered Victor Bolden's fumble on the second half kickoff at the Oregon State 12, Gaffney scored from the 9 two plays later.
