Duke completed its regular-season sweep of rival North Carolina with a 84-77 win at the Smith Center on Saturday night.

North Carolina took a two-point lead into the locker room, but the advantage should have been larger due to Duke's poor shooting.

The visiting Blue Devils missed 12 consecutive shots during a half in which they shot 33.3 percent from the field.

The Tar Heels failed to take advantage of a stretch midway through the second half when Jahlil Okafor, Justise Winslow and Tyus Jones were all on the bench. Instead of UNC opening up a big gap, Duke closed it and took the lead.

Duke opened up a nine-point lead with 5:30 left in the game after Tyus Jones and Quinn Cook hit back-to-back threes.

After extending the lead during that key span, the Blue Devils never turned back in Chapel Hill.

Jones led all scorers with 24 points, while his backcourt partner Cook contributed 20 in the winning effort.

Marcus Paige led the Tar Heels with 23 points, including a 5-for-9 effort from beyond the arc.

If there is to be a third meeting between the two rivals, it would come in the final of the ACC tournament (or the NCAA tournament).

Duke heads to Greensboro as the No. 2 seed, while North Carolina will start the tournament Wednesday as the No. 5 seed.
