BIG 12

* No. 4 Oklahoma 17, at Iowa State 7: Chris Brown ran for two second-half touchdowns and the Sooners (7-1, 3-1) survived a major scare from the Cyclones (1-7, 0-4) at Ames. D.J. Wolfe’s interception in the end zone midway through the fourth quarter helped turn the tide for Oklahoma, which won at Iowa State for the 20th straight time. Oklahoma improved to 67-5-2 against Iowa State, but the Sooners scored 31 points below their season average, against the Big 12’s worst defense.

* No. 15 Kansas 19, at Colorado 14: The Jayhawks (7-0, 3-0) forced three turnovers and stopped the Buffaloes (4-4, 2-2) on downs twice in the fourth quarter, escaping with their first win in Boulder since 1995. Kansas has won seven straight to start the season for only the second time since 1968.

* No. 19 Texas 31, at Baylor 10: Colt McCoy overcame two interceptions, missing a wide-open receiver in the end zone and a personal foul penalty with 293 yards passing and a touchdown as the Longhorns (6-2, 2-2) beat the Bears (3-5, 0-4) at Waco, Texas. This 10th straight victory over Baylor wasn’t nearly as easy as most have been for Texas, which won the previous nine games by an average of 41 points.

* at Oklahoma State 41, No. 25 Kansas State 39: Jason Ricks kicked a 26-yard field goal with two seconds left and the Cowboys (5-3, 3-1) overcame the best passing performance of Josh Freeman’s career to beat the Wildcats (4-3, 2-2) at Stillwater. Freeman threw for 404 yards, and star wide receiver Jordy Nelson caught three touchdown passes.

* Texas A&M; 36, at Nebraska 14: Stephen McGee rushed 35 times for 167 yards and Jorvorskie Lane rushed for 130 yards and four touchdowns, leading the Aggies (6-2, 3-1) over the Cornhuskers (4-4, 1-3) at Lincoln.
