Deshaun Fenwick rushed for two scores on just five carries, but Washington edged 23rd-ranked Oregon State, 24-21, in Husky Stadium.
Fenwick crossed the goal line on rushes of two and 19 yards and Easton Mascarenas-Austin returned an interception for a score.
The second touchdown run by Fenwick gave the Beavers a 21-14 advantage, but the Huskies answered with the game's final 10 points to take the win on Friday night.
Damien Martinez led the Beaver offense with 107 yards on the ground on 19 attempts.
Ben Gulbranson threw for 66 yards on 11 completions.
Oregon State (6-3, 3-3) was led defensively by Omar Speights, who tallied nine tackles – six of which were solo stops – and broke up a pass. Alex Austin and Kitan Oladapo each collected six tackles, five being solo ones.
The Beavers will return to Reser Stadium to host the California Golden Bears this upcoming Saturday, November 12. The kickoff time is still to be determined, as the Pac-12 has designated it for the six-day window.
