NORMAN — DeMarco Murray ran for two touchdowns, Ryan Broyles returned a punt 88 yards for a score and Oklahoma knocked No. 11 Oklahoma State out of contention for its first appearance in the Bowl Championship Series with a 27-0 win Saturday.
With representatives of the Fiesta and Orange bowls watching on, the Cowboys (9-3, 6-2 Big 12) fell completely flat with their worst offensive performance of the decade.
Oklahoma State was shut out for the first time since 2005 by an Oklahoma (7-5, 5-3) defense coming off its worst outing of the year in a loss at Texas Tech last week.
Zac Robinson threw for only 44 yards on 9-for-21 passing after missing last week's game with injuries to his head and shoulder. He was pulled in the fourth quarter with his lowest passing total since taking over as the starting quarterback early in the 2007 season.
Broyles, who decommitted from Oklahoma State to play for the Sooners, also had 103 yards receiving. Patrick O'Hara, the walk-on who had never played football before taking over as Oklahoma's kicker two weeks ago, hit field goals from 24 and 19 yards.
The Sooners have won seven in a row in the Bedlam rivalry and 30 straight home games, the longest streak in the Bowl Subdivision.
Broyles' 47-yard reception set up Murray's first scoring run, a 13-yarder that he punctuated by leaping from the 4-yard line out of bounds past where the goal line would have extended. He also had a 12-yard TD run following Robinson's only interception, which safety Jonathan Nelson returned 37 yards.
The crowd started chanting “Overrated!” after Broyles let Quinn Sharp's punt sail over his head, then fielded the bouncing punt, turned around and raced 88 yards to make it 27-0.
The shutout was preserved when tight end Trent Ratterree tracked down Justin Gent from behind on a fumble return in the final minute, stripped the ball and recovered it. That allowed Oklahoma to run out the clock.
