AUSTIN, Texas (Ticker) -- Sydmill Harris scored 13 points and capped a key second-half run with a 3-pointer as 14th-ranked Texas posted a 76-63 triumph over Big 12 Conference rival Colorado.
Kenton Paulino also had 13 points - a career high - for Texas (15-3, 6-1 Big 12), whose lead was down to 48-45 following a jumper by Colorado's Lamar Harris 4 1/2 minutes into the second half.
But Jason Klotz had a basket in the paint to spark a 9-2 run that Sydmill Harris capped with a 3-pointer with 13:32 to go.
Colorado (12-7, 4-4) got no closer than eight and trailed by as many as 14 down the stretch.
"Midway through the second half, we couldn't get stops and we turned the ball over too much," Colorado forward Michel Morandais said. "Going into the second half, we felt good about being down only three."
Sydmill Harris was 4-of-5 from the field, 3-of-3 from 3-point range. He had not scored in double figures since December 4.
"Sydmill is starting to get his confidence back," Texas coach Rick Barnes said. "He's playing great defense and making a concious effort to guard."
"It's good to be back," Sydmill Harris said. "Coach has been doing a great job of spreading out the playing time, and I knew that if I kept practicing hard, I would get my chance."
Paulino also shot well, making 4-of-6 shots - all from beyond the arc. The Longhorns shot 56 percent from the field (29-of-63) and made 11-of-24 3-point attempts.
"I think the more playing time I get, the more I am starting to get a feel for the game," Paulino said. "It is not that I'm being more aggressive, but that my shots are starting to fall."
Brandon Mouton had 11 points but made just 5-of-16 shots for Texas, which was playing at the Frank Erwin Center for the first time since its 25-game home winning streak was snapped January 24.
David Harrison had 18 points and Morandais chipped in 15 for Colorado, which has lost four straight in Austin.
"Texas and Missouri are the deepest and most talented teams in the Big 12 and they really had guys step up," Colorado coach Ricardo Patton said. "That's what separates teams from the Final Four and the ones that don't get there - they just don't depend on one or two guys."
Texas led, 25-15, following a jumper by James Thomas just over 12 minutes into the contest. The Longhorns were ahead, 38-26, with 3:12 left in the half, but the Buffaloes closed it with nine straight points.
Harrison and Morandais combined to score 23 of Colorado's 35 points in the opening half.
The Buffaloes shot 39 percent (22-of-54) from the field. They are 9-0 this season when holding an opponent under 40 percent.
