M'Baye lofted the ball and Osby dunked the ball to give him to 10 points going into halftime. Osby went 5-of-6 from the floor in the first half.
In the second half, the Sooners had two more alley oops. The first from Sam Grooms to Cam Clark came with under nine minutes left, and the second to M'Baye came about a minute later — with a little showboating to boot.
After M'Baye's dunk, the Texas fans started to boo. After all, M'Baye followed the dunk with a downward Hook 'em Horns sign.
Oklahoma beat Texas in its last meeting on Jan. 21. The Sooners haven't swept Texas since the 2004-2005 season.
An announcement was made at Frank Erwin Center before the game asking upper deck fans to come fill in the mezzanine. Almost the entire upper deck was empty. The basketball center holds 16,540.
Going into the game, the Longhorns had the second-best 3-point defense. Oklahoma drained seven 3-pointers in the first half.
