STILLWATER, Okla. (AP) — Mason Rudolph passed for 352 yards and five touchdowns, and No. 12 Oklahoma State tried to strengthen its case for a playoff spot in a 49-29 upset against No. 5 TCU on Saturday.
James Washington caught five passes for 184 yards and three touchdowns for the Cowboys, who have felt overlooked all season, despite their unbeaten record.
The Cowboys (9-0, 6-0 Big 12, No. 14 CFP) have won their first nine games in a season for just the third time in school history.
TCU's Trevone Boykin, who has generated Heisman buzz all season, passed for 445 yards and ran for 73 yards and two touchdowns. But he also threw a career-high four interceptions. TCU (8-1, 5-1, No. 8 CFP) gained 663 yards, but the Horned Frogs were held scoreless in the red zone twice.
TCU's Josh Doctson, the nation's leader in receiving yards, left the game in the second quarter with a left wrist injury and did not return.
Shaun Nixon had career highs of nine catches and 146 yards, and KaVontae Turpin added seven catches for 107 yards for the Horned Frogs.
Washington picked up right where he left off last week. The sophomore speedster had 200 yards on four catches against Texas Tech, with touchdown catches of 75 and 73 yards in the fourth quarter. He had catches of 48 and 50 yards in the first nine minutes against TCU.
Rudolph connected with Jeff Carr on a screen pass for a 12-yard score that put the Cowboys up 21-9 early in the second quarter.
After stopping TCU on fourth down in the red zone, Oklahoma State struck quickly. Rudolph connected with Marcell Ateman for an 83-yard touchdown pass to put the Cowboys up 28-9.
Early in the second half, Oklahoma State linebacker Chad Whitener intercepted Boykin and returned it to the TCU 1-yard line. J.W. Walsh scored on the next play to make it 35-9.
Whitener took Boykin's fourth interception back 42 yards for a touchdown with 44 seconds remaining.
