LUBBOCK, Texas (AP) - Clint Chelf threw for two touchdowns and a season-high 211 yards and ran for two more scores to lead No. 18 Oklahoma State past No. 15 Texas Tech 52-34 on Saturday night.
Desmond Roland ran for three touchdowns, a week after getting four for Oklahoma State (7-1, 4-1).
Chelf scored on a 67 yard quarterback draw, and was 18-for-34 passing with two interceptions.
The win keeps Oklahoma State in the Big 12 title hunt and makes the road for Texas Tech (7-2, 4-2) more difficult. The Red Raiders have lost two straight.
Cowboys returner Josh Stewart set up the last of Roland's touchdowns after returning a punt 46 yards in the third quarter.
Davis Webb was 45 for 71 for 425 yards and a touchdown, with two interceptions, for Texas Tech.
Jace Amaro finished with 174 yards and a touchdown on 15 catches for the Red Raiders.
