NORMAN, Oklahoma (Ticker) -- Oklahoma was a little bit better from the outside this time but had no answer inside for Texas.
Brandon Mouton scored 25 points and Jason Klotz grabbed a key rebound as the 12th-ranked Longhorns extended their winning streak against Oklahoma to a school-record four games with a 68-63 Big 12 Conference victory.
The Sooners (16-7, 6-6 Big 12) made just 1-of-21 3-pointers in a 66-37 loss at Texas on February 8. They were 7-of-21 from the arc in this one to stay close but were outscored in the paint, 26-6, and outrebounded, 46-30.
"If you don't have big, strong bruisers in there, you better either be quick and athletic or big and strong," Oklahoma coach Kelvin Sampson said. "I felt like our kids banged in there, I thought our kids played hard."
James Thomas and freshman P.J. Tucker led the effort under the basket with 12 and 11 rebounds, respectively.
Texas (19-4, 10-2) led by as many as seven points in the second half, but Oklahoma tied it, 63-63, on a three-point play by Jason Detrick.
Mouton split two free throws 13 seconds later to break the deadlock and Klotz grabbed the rebound of the miss.
"They have great rebounders in Jabahri Brown and Johnnie Gilbert, and they are real athletic," Klotz said. "I was just trying to get in there quick and get in there strong and get rebounds."
Royal Ivey found Tucker for a backdoor layup with 26.2 seconds remaining, then sealed the win with a pair of free throws after De'Angelo Alexander missed a layup for the Sooners.
"All we needed was one stop and we had a shot at winning," Oklahoma freshman Drew Lavender said. "We got a tough call at the end and then did not get a key rebound after Mouton's miss."
Mouton was the only player in double figures for the Longhorns, who have won consecutive games at the Lloyd Noble Center for the first time in school history.
"I just felt good out there," Mouton said. "I think we learned a lot from the Iowa State game, and that is if you get a lead, you cannot relax out there. Defense helps get the lead, but the offense keeps it for you, so we just kept that mentality out there."
Lavender scored 18 points and Detrick finished with 14 for Oklahoma, which has dropped three of its last five games.
"We put ourselves in a position to have a chance to win the game," Sampson said. "Sometimes it comes down to breaks. As this year has gone along, we have proved that we haven't gotten a lot of breaks."
Brad Buckman had nine points off the bench for Texas, which trailed by a point at halftime but shot 52 percent (13-of-25) in the second half.
The Sooners got 12 points from Alexander and 10 from Lawrence McKenzie but shot under 36 percent (19-of-53).
