The biggest reason for Oklahoma State's 24-17 victory over Texas Tech could be found in the trenches.

An offensive front keyed by awards nominee Russell Okung opened enough holes in the second half to keep the Cowboys' South Division title hopes alive.

OSU piled up 207 rushing yards in the second half, controlling the ball for more than 22 minutes after intermission.

One negative coming out of the game was an apparent concussion sustained by OSU quarterback Zac Robinson on a devastating hit by Tech cornerback Jamar Wall.

With the Cowboys playing Thursday night against Colorado, it might be asking a lot for Robinson to return to action that soon.

And Robinson was the key before his injury. He piled up a team-high 97 yards. Keith Toston added 78 and Kendall Hunter had his most impressive performance since returning from his foot injury with 70 tough yards on 17 carries.

It was an impressive performance that pushes the Cowboys into the driver's seat for the Big 12's top bowl berth outside the BCS in the Cotton Bowl.
