Abdul-Malik Abu added 19 points for the Wolfpack (14-7, 3-5 Atlantic Coast Conference), who earned the program's first win at Duke's famously hostile Cameron Indoor Stadium since 1995.

N.C. State ran off a 20-5 run to erase a 68-59 deficit in the final 6 minutes, then got one final stop when Jayson Tatum lost control of the ball before getting a shot off on Duke's final possession.
N.C. State shot 55 percent after halftime, with Smith dominating the Blue Devils (15-5, 3-4) all night and finishing 10 for 18 from the floor with six assists.
"We've taken a few hits obviously," Wolfpack coach Mark Gottfried said. "I think it shows a lot about character after you take a few hits to come and win a game like this here. I thought our guys dug down deep and Dennis made some sensational plays, but I think a lot of guys stepped up and made big plays for us."
Luke Kennard finished with 20 points to lead Duke, which shot just 38 percent after halftime.
"Dennis was tremendous all game long," Duke associate head coach Jeff Capel said. "He's a very talented kid, and played lights-out basketball tonight."
NOTES
N.C. State: Can anyone figure out the Wolfpack?
There's plenty of young talent, but this group lost by 51 points at rival North Carolina earlier this month to start a stretch of four losses in five games.

Yet N.C. State responded with the kind of consistently determined effort it hadn't shown much this season, hanging in even when Duke threatened to stretch out the lead and finding a way to push back with an impressive showing.
Duke: The Blue Devils just couldn't corral Smith all night, and associate head coach Jeff Capel - leading the team in Mike Krzyzewski's absence following back surgery - is still tinkering with lineups and rotations.
He brought Kennard and Grayson Allen off the bench for this one, and Duke kept threatening to make this one look like so many games before at Cameron.

And yet, when Smith and the Wolfpack made their move, the Blue Devils struggled for an answer in the deciding minutes.
