Kaylon Williams and Gioya Carter led the Sooners (15-6, 6-4 Big 12) with 15 points.
Jordan Moore's 3-point play with 8:04 remaining gave TCU a 55-52 lead but the Horned Frogs had five turnovers and two misses in their next six possessions and the Sooners ran off 10 straight points. Pierre-Louis started the run at 7:32 and ended it at 4:28.
Moore had another 3-point play at 3:56 but Gioya Carter answered with a jumper and Pierre-Louis followed with a 3-point play, making it 67-58 with 2:32 to go. After Jada Butts had a 3-pointer for the Horned Frogs at 2:10, the Sooners made all eight free throws in the final two minutes.
