Texas (22-4, 10-2) looked abysmal on both sides of the court and never got things going, while Oklahoma State (14-12, 4-8) played with unparalleled intensity and emotion and put the game nearly out of reach as early as halftime.
Playing amidst banners showing support for their legendary coach, the Cowboys out-hearted Texas to hold the Horns to a mere 33.3 percent shooting from the field, while OSU finished with a sizzling 50.8 shooting percent on the afternoon.
The Horns came into the contest with a five-game winning streak, while the Cowboys had lost seven of their previous eight, but it did not show on Saturday.
Texas perimeter players shot off target all night, sinking only 5-of-21 (23.8 percent) from behind the arc, while the Cowboys drained nearly half of their long distance attempts (7-of-16, 43.8 percent).
The game started innocently enough for Texas, with the Horns trailing by one point five minutes in after Aldridge scored the first four points for Texas and Gibson added a three pointer. Gibson went on to finish with 11 points after getting into early foul trouble.
The pace slowed down in the next few minutes until OSU climbed to a five-point lead with a JamesOn Curry jumper. Curry slashed his way past Longhorn defenders all afternoon and finished his day with a game-high 22 points.
In the final four minutes of the half, Texas settled for just free throws, while the Cowboys knocked down several field goals and a three pointer at the buzzer to cap off a 13-6 run that gave the Cowboys an 11-point halftime advantage.
Texas showed signs of life at the start of the second half, with Tucker connecting on a jumper and Paulino scoring a three pointer to pull the Horns to within eight, despite a flurry of Curry buckets.
The OSU lead hovered around 10 points for the next couple of minutes after Buckman, Paulino, Aldridge and Gibson each made a shot from the floor to respond to OSUs sharp shooting. The Cowboys caught fire again and went on a 10-2 run until a pair of Buckman free throws ended the streak.
The damage had been done, though, and the Cowboys rolled through the final eight minutes of play for the blowout.
