CORVALLIS, Ore. (AP) -- B.J. Baylor had 20 carries for 110 yards and two touchdowns, Everett Hayes kicked a 24-yard field goal as time expired and Oregon State beat Washington 27-24 on Saturday night.
It's still relatively early in the season, but Oregon State's win combined with Stanford's upset of No. 3 Oregon in overtime puts the Beavers (4-1, 2-0 Pac-12) in first place.
Oregon State snapped a nine-game losing streak to Washington (2-3, 1-1 Pac-12) and is 2-0 in conference play for the first time since 2013.
Oregon State rallied for its fourth consecutive win after losing the lead in the fourth quarter.
A strip-sack of Oregon State quarterback Chance Nolan by Faatui Tuitele at the OSU 13 and fellow defensive lineman Sam Taimani's recovery and 13-yard run set up Sean McGrew's 6-yard touchdown run, giving Washington the lead at 24-17 with 10:02 left.
Back came the Beavers.
A 19-yard run on a reverse to wide receiver Anthony Gould, followed by Gould's 22-yard reception set up Baylor's 27-yard run to tie the game at 24-24 with 6:35 remaining.
McGrew was stopped inches short of a first down on a fourth-and-1 direct snap run near midfield at the 3:18 mark. The spot was upheld on an official's review.
McGrew's 39-yard touchdown run up the middle tied the game at 17-17 with 10:19 remaining. Dylan Morris' 18-yard pass to Kamari Pleasant on third and 18 deep in Huskies territory kept the drive alive.
Oregon State gained momentum early in the second quarter.
Cornerback Rejzahn Wright recovered Cameron Davis' fumble at the Huskies' 12. The turnover led to Jack Colletto's 3-yard touchdown run and a tie game at 7-7.
The Beavers took their first lead at 14-7 on B.J. Baylor's 5-yard touchdown around right end midway through the second quarter.
Peyton Henry converted a 20-yard field goal on the final play of the first half and the Beavers led 14-10 at the break.
Hayes made a 29-yard field goal to increase the Oregon State's lead to 17-10 at 5:28 of the third quarter.
Washington took the opening kickoff and marched 75 yards for the score, culminated by a 44-yard pass to a wide-open Terrell Bynum, who was not touched on his way to the end zone.
