Seattle • Bishop Sankey ran for 92 yards and two touchdowns, Travis Coons kicked a 30-yard field goal with 1 minute, 20 seconds left and Washington took advantage of four interceptions from Oregon State's Sean Mannion in a 20-17 upset of the seventh-ranked Beavers on Saturday night.
Oregon State (6-1, 4-1 Pac-12) was trying for the first 7-0 start in school history. It instead became the second top 10 team to be upset by the Huskies at home this season. Washington knocked off then-No. 8 Stanford 17-13 in late September.
Mannion, who is returning from minor knee surgery, threw interceptions on consecutive possessions early in the fourth quarter after Oregon State had rallied from a 10-0 halftime deficit to pull even with a dominating third quarter. The last of Mannion's four picks was snagged by Marcus Peters, and Sankey scored from the 1 to give Washington (4-4, 2-3) a 17-10 lead two plays later.
Oregon State backup Cody Vaz entered and threw a 29-yard TD pass to Connor Hamlett with 4:58 left to pull the Beavers even. But Keith Price led the Huskies 63 yards in 3:38 for Coons' go-ahead field goal and snapped Washington's three-game skid.
Oregon State's win over Utah last week gave the Beavers their first 6-0 start in more than 100 years, but the biggest surprise in the Pac-12 finally stumbled even with its starting quarterback returning.
Mannion never got into a rhythm. He often was late with his throws or threw behind receivers and wasn't helped by the loss of star Markus Wheaton to a probable concussion in the second quarter on a pass that was knocked from Wheaton's hands and to Washington safety Justin Glenn for one of Mannion's four picks.
Mannion finished 18 of 34 for 221 yards and one touchdown.
