Romero Osby scored a career-high 29 points, Amath M'Baye had three rim-rattling dunks among his 15 points and Oklahoma snapped a six-game Red River Rivalry losing streak by beating Texas 73-67 on Monday night.
Osby scored 21 of Oklahoma's 33 points during a 14 1/2-minute chunk in the middle of the game, powering the Sooners (13-4, 4-1 Big 12) to their first win against the Longhorns since he transferred from Mississippi State. Texas had swept both meetings last season and all three in 2011 while Osby was sitting out under NCAA transfer guidelines.
Off to its worst start to conference play since 1976, Texas (8-10, 0-5) had no answer for Osby after top rebounder Jonathan Holmes left with a right wrist injury with just under 7 minutes left in the first half. Osby checked back into the game about 3 minutes later and took over.
Sheldon McClellan came off the bench for the fourth straight game and led the Longhorns with 25 points.
