DALLAS (Ticker) -- No. 6 Oklahoma did not give Colorado a chance to pull off another wild win.
Hollis Price and Quannas White scored 19 points apiece as Oklahoma continued its quest for a third straight Big 12 Conference tournament title with a 74-59 quarterfinal victory over Colorado.
Oklahoma (22-6), which has won seven straight conference tournament games, will face Texas Tech in Saturday's semifinals.
"We're not worried about the No. 1 seed (in the NCAA Tournament) right now," Price said. "We're just trying to get through the Big 12 tournament. If we can do that, get another championship, then we can be happy with that."
Price, the Big 12 Player of the Year, scored 13 points in the opening 20 minutes as the Sooners (22-6) grabbed a 40-32 halftime lead.
But Colorado was undaunted, having reached the quarterfinals with a 77-76 victory over Kansas State on Thursday as Mookie Wright banked in a 3-pointer at the buzzer.
That shot capped a wild sequence of events and came right after an inbounds pass from Wright was picked off by the Wildcats' Pervis Pasco - who started running with the ball and was whistled for a travel that gave the Buffaloes a final chance with 1.8 seconds to go.
Michael Morandais' jumper with 9:14 left on Friday capped a 15-6 run and pulled Colorado within 56-51. But White made two of his five 3-pointers - which matches a career high - as Oklahoma closed the contest on an 18-8 run.
"We determined we had to pick it up defensively," White said. "We slowed down a little bit and they cut the lead down. So I just told everybody we needed to pick it up defensively."
The Sooners overcame foul trouble in their frontcourt as 6-10 center Jabahri Brown and 6-8 freshman Kevin Bookout picked up five fouls apiece and 6-8 forward Johnnie Gilbert was whistled for four.
"The last two games we've really struggled with foul trouble," Oklahoma coach Kelvin Sampson said. "Adversity in a basketball game comes in many different forms. A bad shooting night, an injury, a lot of things can be adverse during the course of a game. The last two games our foul trouble has been ridiculous."
David Harrison paced Colorado with 12 points. But none of his teammates reached double figures and the Buffaloes (20-11) had their four-game winning streak snapped.
"We kept cutting into the lead," Colorado coach Ricardo Patton said. "We had our chances and we didn't make our free throws. To win tournaments, you've got to do the little things, all of which they did. ... That's something this team is still figuring out."
Colorado forward Stephane Pelle, who had 11 rebounds in the win over Kansas State, pulled down a season-low two boards as the Buffaloes were outrebounded, 37-30.
