Norman, Okla. ? With an assist from Mother Nature, No. 12 Oklahoma got its defense back in order and set up a Bedlam showdown for the Big 12 championship.

Landry Jones threw for 256 yards, Blake Bell punched in two short touchdown runs, and the Sooners limited Iowa State to a season-low 245 yards in a 26-6 victory on Saturday.

Rebounding after allowing a school-record 616 yards allowed last week in a 45-38 loss at Baylor, Oklahoma only let the Cyclones (6-5, 3-5 Big 12) score after James Winchester’s snap sailed over the head of punter Tress Way in the first quarter.

Oklahoma will visit No. 4 Oklahoma State — the nation’s second-highest scoring offense — next week, and the winner earns the Big 12 title.

Trey Franks finished with 88 yards rushing on two long reverses to set up scores for the Sooners (9-2, 6-2), and Michael Hunnicutt matched his career-high with four field goals on a difficult day for offense.

Each team turned it over four times in a game played in front of thousands of empty seats at sold-out Owen Field, with sustained winds of over 30 mph and gusting to more than 40 mph. The game-time winds were the strongest in Norman since a 1964 loss against Southern California.

The Cyclones didn’t sustain a drive of longer than 35 yards and got their only points on Jared Barnett’s 10-yard touchdown pass to Albert Gary one play after Oklahoma’s botched punt. They were shut out the rest of the way.
