David Noel added 14 for North Carolina (9-2, 1-0 Atlantic Coast Conference), which won its fifth straight in this Tobacco Road rivalry. This was the first time since Jan. 20, 1990, that N.C. State came in with a higher ranking, but it hardly mattered to the Tar Heels.
They scored the final 13 points during the last 2 1/2 minutes to break free from a tie game and made the final margin deceptively large. While Frasor had none of those points, he had perhaps the biggest play, jumping in the passing lane for his steal with North Carolina clinging to a 73-69 lead.
The turnover led to two free throws from Hansbrough, and the Wolfpack never recovered. Noel capped the stunning conclusion with his second breakaway dunk, throwing this one down with both hands to punctuate the Tar Heels' 21st victory in the past 29 games against N.C. State.
Ilian Evtimov finished with 15 points and teammate Tony Bethel had 13 for the Wolfpack (12-2, 1-1), who saw their best start in 17 years stopped.
In the first 3 1/2 minutes, it appeared this one might be different. The Wolfpack jumped to an 11-0 lead, an opening spurt that included a spectacular dunk by Cameron Bennerman. He beat every one to the other end following a steal and left the floor just inside the foul line.
But North Carolina quickly rallied and eventually took an eight-point lead late in the first half. N.C. State came back, too, and the second half settled into a back-and-forth struggle controlled mostly by Frasor.
He put back a miss by Wes Miller to tie it, then had a layup to help the Tar Heels take a 54-48 lead. With the margin down to three about 3 minutes later, Frasor banked in a jumper, added another basket from in close and completed his run with his only 3-pointer of the game.
Yet the Wolfpack fought back to another tie, with Bennerman finishing off another steal with an acrobatic layup to make it 69-69. Hansbrough gave North Carolina the lead with a dunk off an assist from Noel, and Frasor's steal made sure the Tar Heels hung on.
They finished 26-for-28 at the line and shot 53 percent from the field, the first time this season N.C. State has allowed an opponent to make at least half its shots.
