DURHAM, N.C. (AP) - 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 scored 20 points and Reggie Bullock had 15 points with four 3-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.
