– By dominating previously unbeaten TCU on Saturday, Oklahoma State gained control of the Big 12 championship race, and perhaps much more.

Mason Rudolph passed for 352 yards and five touchdowns, James Washington caught five passes for 184 yards and three touchdowns, and the 12th-ranked Cowboys pulled off a 49-29 upset of the fifth-ranked Horned Frogs.

Oklahoma State travels to Iowa State next week, then the Cowboys face No. 2 Baylor and No. 14 Oklahoma at home. Win those, and Oklahoma State (9-0, 6-0 Big 12, No. 14 CFP) will be the undisputed Big 12 champion with a strong argument for a spot in the College Football Playoff.

"I'm not going to disregard that we're playing teams that are ranked high enough that we could make up some ground," Oklahoma State coach Mike Gundy said. "But I just continue to stress for us, we have to practice well tomorrow."

In the College Football Playoff rankings, the Cowboys are behind five teams that entered the weekend with a loss.

"We felt a bit snubbed, but our body of work has and will put us where we need to be," Oklahoma State linebacker Chad Whitener, who intercepted two passes and ran one back for a touchdown against TCU, said.

TCU's Trevone Boykin, who has generated Heisman Trophy buzz all season, passed for 445 yards and ran for 73 yards and two touchdowns, but he also threw a career-high four interceptions.

"I used the Kevin Durant example, the one where you don't let him get to 50 points, just let him get to 25," Gundy said. "That's what we did tonight."

TCU (8-1, 5-1, No. 8 CFP) gained 663 yards, but the Horned Frogs were held scoreless in the red zone twice as their 16-game win streak ended. "They kicked our butt. It's as simple as this," TCU coach Gary Patterson said.

TCU's Josh Doctson, the nation's leader in receiving yards, left in the second quarter because of a left wrist injury and did not return.
