Javan Felix scored 27 points, making six 3-pointers and No. 19 Texas rolled to an 87-68 win over Oklahoma State, which played its first game Tuesday night without suspended star Marcus Smart.
Smart sat out the first of a three-game suspension by the Big 12 for shoving a Texas Tech fan. Without him, the Cowboys never had a chance.
Felix scored eight consecutive points that pushed Texas' lead to 22 early in the first half. The Longhorns (19-5, 8-3) led 54-33 at halftime despite playing without leading scorer Jonathan Holmes, who sat out with a knee injury.
Smart, who averages 18 points, will miss games against Oklahoma and Baylor before returning for the Cowboys' rematch with Texas Tech.
Le'Bryan Nash led Oklahoma State (16-8, 4-7) with 23 points.
