CHAPEL HILL, N.C. — Grayson Allen scored 23 and freshman Derryck Thornton came up with the clinching block on the final play to help No. 20 Duke edge No. 5 North Carolina 74-73 on Wednesday night.
Allen hit two free throws with 1:09 left for the lead on a night when the Blue Devils (20-6, 9-4 ACC) trailed most of the way. Then Duke came up with two stops in the final minute, first on a shot attempt inside in traffic by Kennedy Meeks.
Then, on UNC's final possession, Thornton blocked Joel Berry II's shot in the lane. Allen rebounded the ball and flung it into the air to let the final seconds expire. The players raced to the bench to mob each other and celebrate.
Brice Johnson had 29 points and 19 rebounds in a dominating performance for the Tar Heels (21-5, 10-3), who came in with a decided edge in size and depth. But Johnson got little help outside of Justin Jackson's 13 points, with the Tar Heels sputtering down the stretch after leading by eight with about seven minutes left.
Most notably, UNC senior guard Marcus Paige — the preseason ACC co-player of the year — finished with seven points on 2-for-10 shooting, including 0-for-6 from 3-point. Paige had three turnovers.
It was a tough-nosed performance by the Blue Devils, who came in shorthanded with largely a six-man rotation in the wake of small forward Amile Jefferson's injury earlier this season then lost guard Matt Jones to a first-half ankle injury.
What was left was enough, with freshmen Brandon Ingram (20 points) and Luke Kennard (15 points) coming up with huge baskets down the stretch.
