DURHAM, N.C. - Mason Plumlee had 18 points and 11 rebounds and No. 2 Duke beat North Carolina 73-68 on Wednesday night.
Quinn Cook scored 18 points and Rasheed Sulaimon finished with 13 for the Blue Devils (22-2, 9-2 Atlantic Coast Conference).
They shot 44 percent - 52 percent after halftime - and used a big run in the second half to erase a slow start and win their sixth straight this season and sixth in eight meetings in college basketball's fiercest rivalry.
P.J. Hairston matched a career high with 23 points and Reggie Bullock had 15 points with four three-pointers for North Carolina (16-8, 6-5), which led for the first 26 minutes but went on to lose its second straight.
The Tar Heels were 13 of 23 from the free-throw line and missed 7 of 10 during a critical late stretch while falling to 1-4 this season against ranked opponents.
The win was a nice present for coach Mike Krzyzewski, who was celebrating his 66th birthday.
The Tar Heels were aggressive early and methodically built a double-figure lead, the third straight year they came into Duke and went up by 10. Bullock's third three-pointer of the first half with about 6:45 left put North Carolina up 28-18.
