BOULDER, Colo.- Derrick White did all he could to try to snap Colorado's losing streak to Utah, but as has been a common theme for the Buffaloes this season, he did not get enough help.
White had 31 points and four blocks for the Buffaloes, who struggled defensively. Utah shot 55.3 percent and hit 25 of 32 free throws while continuing its dominance of Colorado with an 86-81 win on Thursday night.
David Collette added 14 points for the Utes (18-10, 9-7 Pac-12), who won their seventh in a row over Colorado (16-13, 6-10) despite foul trouble.
"Our defense wasn't good enough tonight," Colorado coach Tad Boyle said. "Utah came in here and just schooled us."
The Utes led 71-61 with 4:34 left but had to hold on down the stretch. White scored seven points and three free throws by Dominique Collier got the Buffaloes within two.
After Tyler Rawson split two free throws Collier missed a 3-pointer with 30 seconds left that would have tied it.
Colorado's press nearly created a couple of turnovers but Utah was able to break it and hit their free throws down the stretch.
"We needed that one stop to put us over the edge in this one," said White, who also had six rebounds and five assists.
The Utes used a 17-5 run to take a 12-point lead with 5:25 left in the first half. The Buffaloes trailed by eight at halftime but went on a 7-2 run at the start of the second half to get within 39-36.
The Buffaloes have not been able to solve Utah for three years. Colorado's last win over the Utes was Feb. 1, 2014, in Boulder.
