Romero Osby scored 12 points, Amath M'Baye added 11 and Oklahoma led from start to finish in a 75-48 victory against last-place TCU on Monday night.
The Sooners (16-7, 7-4 Big 12) held TCU scoreless for the first eight minutes and extended their lead to 25 by halftime. Oklahoma led by as much as 36 after Andrew Fitzgerald's three-point play to finish a 13-0 run with 13:17 left in the game.
TCU (10-14, 1-10) responded with its only extended stretch of strong play, scoring nine points in a row. But by then it was far too little, too late. Oklahoma led by at least 20 throughout the second half on its way to surpassing last season's win total.
Devonta Abron led TCU with 12 points and Kyan Anderson scored 11 on 4-for-19 shooting.
