CHAPEL HILL, N.C. — North Carolina finished off its fiercest rival and the ACC regular-season race with one strong performance.
Harrison Barnes had 18 points to help No. 13 North Carolina beat No. 4 Duke 81-67 on Saturday night, clinching the ACC championship and the top seed in the league tournament.
Former Sickles standout John Henson had 10 points and 12 rebounds and Kendall Marshall 15 points and 11 assists as the Tar Heels (24-6, 14-2) ended a three-game losing streak to their rival. North Carolina also avenged last month's loss at Cameron Indoor Stadium in which it blew a 16-point lead in the first half.
Once again, UNC built a big first-half lead, this time 14 points. But Barnes and the Tar Heels protected that margin Saturday and stayed in control the entire game.
Nolan Smith had 30 points for Duke (27-4, 13-3). Seth Curry had 20 points with six 3-pointers.
In many ways, it was a replay of the first meeting for the Blue Devils. Just as before, Smith and Curry carried the offense while Kyle Singler struggled to make much of anything while matching up much of the night against Barnes, the heralded recruit who picked North Carolina over Duke and other schools.
But Barnes was more aggressive than in the first meeting, leading an offense that shot 52 percent, highest against Duke in a league game this season. Barnes shot 3-of-8 and had nine points in the first game but went 7-of-17 in this one.
