Halftime: UNC 39, Texas 23

CHAPEL HILL, N.C. – With a little more than four minutes left in the first half, North Carolina coach Roy Williams grabbed a towel and helped soak up a wet spot in the middle of the Smith Center court.

It’s sort of fitting for the game so far, considering his No. 5/6 Tar Heels -- who lead 39-23 at halftime -- are wiping the floor with Texas so far.

A 13-1 run put the Tar Heels up over the younger, shorter Longhorns early, 19-7. Texas cut into the lead with a 7-2 run of its own, but then UNC put on a sprint that had the home crowd louder than it has been all season.

First, reserve guard P.J. Hairston took a pass from point guard Kendall Marshall, drove from the wing, and threw down a one-handed transition dunk that had Texas’ Julien Lewis on his back – after he was whistled for the foul.

Hairston missed the free throw, but on UNC’s next possession, forward John Henson followed with a two-handed dunk. On the Heels' possession after that, reserve Reggie Bullock scored in transition – on a ball batted to him by Henson. That gave UNC a 30-16 advantage.

Harrison Barnes leads the Tar Heels – who are shooting 42.4 percent – with 7 points. Tyler Zeller has 6 points and 7 rebounds.

Texas has made only a quarter of its shots, and Jonathan Holmes has scored 10 of it points.

UNC has scored 13 points off turnovers.
