CHAPEL HILL, N.C. — Jon Scheyer had 24 points and eighth-ranked Duke pulled away in the final minutes to beat North Carolina 64-54 on Wednesday night.
Kyle Singler added 19 points for the Blue Devils (20-4, 8-2 ACC), who shot poorly and couldn't make much of anything in close. But boasting a bigger and tougher front line than in years past, Duke dominated the boards and got plenty of extra looks.
Duke hit nine 3-pointers but shot 32 percent overall and went 13-of-51 (25 percent) from inside the arc.
The defending national champion Tar Heels (13-11, 2-7) have lost eight of 10 since the start of 2010, including four in a row overall to fall near the bottom of the league standings.
Will Graves had 13 points to lead North Carolina.
The Tar Heels, who started the season at No. 6 and as co-ACC favorite with Duke, fell out of the AP poll two weeks ago.
Still, this one fit in with college basketball's fiercest rivalry when it came to intensity and fight. Neither team led by more than six in the first 30 minutes, and they were tied with about eight minutes left before the Blue Devils finally took control.
At halftime, the Tar Heels retired the No. 50 of Tyler Hansbrough, the leading scorer and rebounder in school history.
NO. 2 SYRACUSE 72, UCONN 67: Wes Johnson and Kris Joseph combined to make six straight free throws in the final 33 seconds, and the host Orange (24-1, 12-1 Big East) won its 11th straight game and snapped a six-game regular-season skid against the Huskies.
NO. 13 OHIO ST. 69, INDIANA 52: William Buford had 21 points and Kyle Madsen a career-high 11 for the visiting Buckeyes (19-6, 9-3), who have won eight straight Big Ten games and four straight over the Hoosiers.
NO. 19 N. IOWA 57, DRAKE 48: Adam Koch had 12 points as the visiting Panthers (22-2, 13-1) clinched at least a share of the Missouri Valley title.
MIAMI 64, NO. 20 GA. TECH 62: After blowing a chance to seal the win by missing a one-and-one with 19 seconds left, James Dews hit a 15-footer at the buzzer to lift the host Hurricanes (17-7, 3-7 ACC) over the Yellow Jackets (17-7, 5-5).
NO. 24 BAYLOR 55, NEBRASKA 53: Ekpe Udoh hit the go-ahead basket with 25 seconds left and Quincy Acy made two big defensive plays at the other end to rescue the visiting Bears (18-5, 5-4 Big 12).
TAMPA 80, SAINT LEO 65: Callum Townsend had 17 points off the bench as the visiting Spartans (10-11, 4-8 Sunshine State Conference) ended a three-game losing streak.
FLA. SOUTHERN 78, ECKERD 74, OT: Brandon Jenkins had seven of his 14 points in overtime as the visiting Moccasins rallied to beat the Tritons (13-8, 6-5 SSC).
