Pullman, Washington (AP) — Dylan Riley led No. 21 Boise State to a 31-10 victory over Washington State on Saturday, rushing for 128 yards and two touchdowns in the fourth quarter. Riley, who had only 18 yards in the first half, scored on a 33-yard and a 72-yard run to extend the Broncos' lead to 31-10. Boise State, now 6-1 and 3-0 in the Pac-12, moved into the bowl eligibility race, tying Oregon State at first place.

Washington State, now 1-7 and 0-4, suffered their fifth loss in a row and were eliminated from bowl contention. Quarterback Owen Eshelman started for Washington State for the second straight week, completing 191 yards and throwing one interception. Gaines Gaines scored a 9-yard touchdown run in the opening quarter, aided by a 33-yard pass from Maddux Madsen to Rasean Jones.

Following a 16-play, 73-yard drive capped by Kirby Vorhees' 1-yard touchdown run that was initially ruled short but later upheld, Washington State took a 10-7 lead. Late in the first half, Boise State pulled ahead 17-10 on a 28-yard field goal by Canaan Moore. Jack Stevens scored a 47-yard field goal for Washington State in the third quarter to make the score tied at 10-10.

Madsen connected with Cam Bates on a 6-yard scoring pass to give Boise State a 17-10 advantage to begin the fourth quarter. Boen Phelps intercepted Eshelman on Washington State's final drive, and Riley capitalized on a 72-yard touchdown run to seal the victory. Boise State defensive back Roman Tillmon was ejected late in the game for targeting Eshelman.

Madsen threw for 149 yards and a touchdown, without an interception this season. Washington State's next game will be against San Diego State on Saturday, while Boise State travels to Texas State.
