STANFORD, Calif. (AP) -- Michael Penix Jr. threw four touchdown passes and No. 5 Washington held off a fierce comeback attempt to beat Stanford 42-33 on Saturday for its 15th straight win.
Washington (8-0, 5-0 Pac-12) was stuck in a tight game entering the fourth quarter, facing a third-and-8 while leading by only two points. Penix then converted with a 15-yard pass to Germie Bernard and then found Devin Culp wide open for a 24-yard score that made it 35-26.
But Rome Oduzne lost a fumble in the red zone with Washington in position to put it away in the fourth quarter and Penix threw an interception in the end zone after Stanford (2-6, 1-5 Pac-12) cut the deficit to two points on Justin Lamson's 2-yard run.
The Huskies then got a key stop on a trick play when receiver Tiger Bachmeier's pass on fourth-and-2 from the Stanford 28 was dropped by an open Jayson Raines with 3:20 to play.
Dillon Johnson then scored on a 13-yard run to put the game away for Washington.
Penix threw for 369 yards and connected on two TD passes to Ja'Lynn Polk and another to Odunze. Polk finished with 148 yards receiving.
Ashton Daniels ran for two touchdowns and threw another to Elic Ayomanor but it wasn't enough to prevent the Cardinal from losing its seventh straight home game.
Daniels finished with 351 yards passing, including 146 to Ayomanor, who left late in the third quarter with an injury after a 53-yard catch. Daniels capped that drive with his second TD run to make it 28-26.
Stanford finally broke through in the second quarter when Daniels scored on a 5-yard keeper to tie the game at 7.
Washington responded with back-to-back touchdown drives, including a 92-yard pass from Penix to Polk that was the second longest in school history.
Stanford got two field goals from Joshua Karty in the final 1:05 of the half and only trailed 21-13.
The Cardinal travels to Washington State next Saturday.
