Clint Chelf ran for two touchdowns and No. 12 Oklahoma State stayed in the Big 12 championship chase by beating No. 23 Texas 38-13 on Saturday.
Chelf also threw two scoring passes as Oklahoma State (9-1, 6-1 Big 12) won in Austin for the third straight time. This one may renew pressure on Texas coach Mack Brown, who was dealt his worst home loss in 16 seasons at a time when speculation about his job security had just begun quieting down.
The Longhorns (7-3, 6-1) ended a six-game winning streak and lost control of their destiny in the Big 12. Case McCoy threw for 221 yards and was picked off three times.
Oklahoma State next faces undefeated No. 4 Baylor, which was playing later Saturday.
