DURHAM, N.C. (AP) -- Kyle Singler scored 19 of his 25 points in the decisive first half and No. 4 Duke routed North Carolina 82-50 on Saturday night.
Jon Scheyer had 20 points in his final game at Cameron Indoor Stadium for the Blue Devils (26-5, 13-3), who earned their most lopsided home win over their fiercest rival.
They shot nearly 46 percent -- 51 percent in a dominant first half -- and made eight 3-pointers in beating North Carolina at home for the first time since 2005. Duke clinched a share of its 12th Atlantic Coast Conference regular-season title and wrapped up the No. 1 seed in next week's league tournament.
Freshman John Henson matched a season high with 14 points for the Tar Heels (16-15, 5-11). They endured their worst loss in seven years and had their lowest point total under coach Roy Williams.
