DALLAS (Ticker) -- Texas got physical with Kansas star Wayne Simien and it paid off.
Brandon Mouton scored 18 points and Jason Klotz added 14 as the 11th-ranked Longhorns used a bruising effort to move in the championship of the Big 12 Conference tournament with a 64-60 victory.
Simien collected 31 points and 11 rebounds in Friday's quarterfinal rout of Missouri. But the 6-9 forward had trouble all game against the likes of the 6-10 Klotz and 6-8 Brad Buckman and finished with just nine points on 2-of-8 shooting.
"Defensively we gave a great effort and Mouton made some good plays for us," Texas coach Rick Barnes said. "We knew we had to do a good job on Simien and we did."
Texas (23-6) advanced to meet Oklahoma State in the championship. The Longhorns lost twice to the Cowboys this season.
"The last few times we played them we've turned the ball over at bad times," Barnes said. "They understand their roles and what they need to do, and hopefully we do now too."
Mouton nailed back-to-back 3-pointer to open a 57-49 lead with 4:41 left. Texas still held a 60-52 advantage after Kenny Taylor's three-point play less then two minutes later.
Kansas (21-8) scored the next six points, getting within 60-58 on Simien's two foul shots with 90 seconds to go.
Royal Ivey penetrated and found Klotz for a layup and a four-point lead with 62 seconds remaining. After Jeff Graves scored on a follow shot, Ivey sealed it with two foul shots with 13 seconds left.
"We're comfortable with him at the line," Mouton said. "He's made a bunch of clutch free throws for us throughout his career."
Kansas got off to a terrific start, jumping out to a 13-2 lead on Aaron Miles' jumper nearly 5 1/2 minutes into the contest. Texas missed 10 of its first 11 shots.
The Longhorns methodically worked their way back into the game and Kenny Taylor's 3-pointer finally tied it at 28-28 with 2:20 left before halftime. Klotz's free throws with one second left provided Texas with a 35-33 edge at the break.
"I thought we did a lot of good things early," said Kansas coach Bill Self, who fell to 0-4 vs. Texas. "You have to give Texas credit."
Graves and Keith Langford each scored 14 points for Kansas, which was manhandled into 35 percent (8-of-23) shooting in the second half. The Jayhawks also were just 16-of-28 from the line.
The Longhorns forced 16 turnovers and committed only seven. They also came up with 17 second-chance points off 17 offensive rebounds.
"We played well as a unit, did the little things and stayed together," Ivey said. "We played hard, did a good job of taking care of the basketbal, and rebounded. That's Texas basketball and that's what we do."
