AUSTIN, Texas (Ticker) -- After a less than impressive 40 minutes, Tasheed Carr was unstoppable in the extra session.
Carr scored 13 of his 22 points in overtime as Iowa State ended a five-game losing streak at the Frank Erwin Center with a 92-80 triumph over No. 18 Texas in a Big 12 Conference matchup.
With six points in the first 20 minutes and just three in the second half, Carr did little to lead Iowa State fans to believe their luck would change at Texas, which had won 16 straight home games.
But the freshman guard came alive in overtime, scoring eight of the Cyclones' first 10 points of the period - including a 3-pointer 10 seconds in that snapped a 68-68 tie. After Curtis Stinson made a pair of baskets, Carr scored the next five points - including a three-point play - to cap a 9-0 run that gave Iowa State an 87-76 cushion with 57 seconds remaining.
"I played with confidence. I refused to lose," Carr said. "I wanted to do anything to help my team win. I was willing to take big shots. Opening with the three in overtime was huge for our confidence and it got us on a roll."
"They were really hot," Texas forward Brad Buckman said. "It is hard to stop a hot team in overtime. They knocked down a lot of shots. It's like a dagger in your heart when they just keep knocking down shots."
Iowa State's 24 points in overtime fell two short of the NCAA record set by Vermont in 1998.
Stinson had 17 points and 11 rebounds and Will Blalock added 15, nine assists and seven boards for the Cyclones (11-8, 3-5 Big 12), who have won three in a row.
"We are on a little bit of a run," said center Jared Homan, who had 14 points and eight rebounds. "We have confidence. We stepped it up in overtime in order to win."
"It was the best and most consistent game we have played on the road," said Iowa State coach Wayne Morgan, whose team ended its conference road game losing streak at 28. "We have not won a road game in a long time, so our kids were ecstatic."
Daniel Gibson scored 23 points and Buckman had career highs of 20 and 15 rebounds for the Longhorns (15-6, 4-4), who fell to 4-1 following a loss this season.
"I've got to tip my hat to Daniel," Texas coach Rick Barnes said. "He played 45 minutes in this game and we even had to take some timeouts to help him rest. He really played his heart out."
With the game tied at 5-5, Iowa State used an 8-0 run to build a lead with 13 1/2 minutes left in the first half. But Texas answered with an 8-0 burst of its own to climb within 21-18 with 7:14 to go.
The Longhorns entered the break with a 36-31 advantage, but the Cyclones jumped ahead, 41-37, on a layup by Damion Staple with 18:16 remaining in the second half. After a pair of free throws gave Iowa State a 45-42 lead two minutes later, Texas went on a 7-0 spurt that featured a three-point play by Gibson to move ahead.
The Longhorns increased the advantage to 65-57 with five minutes to go, but the Cyclones ended the second half with an 11-3 run, including Blalock's tying jumper with 38 seconds remaining.
"I think we played the way we wanted to for the first 36 minutes," Gibson said. "The last four minutes, we made a lot of mental mistakes. ... Coach told us we have to learn what to do when it comes to crunch time and get the shots that we want."
Blalock had a chance to win the game for Iowa State in regulation, but his 3-point attempt with four seconds left did not fall.
