Freshman Marcus Paige scored eight of his season-high 19 points in overtime to help North Carolina beat Virginia Tech 72-60 on Saturday.
James Michael McAdoo had 22 points and 10 rebounds and Reggie Bullock added 11 points for the Tar Heels (15-6, 5-3 Atlantic Coast Conference).
They hounded the nation's leading scorer, Erick Green, into his second-worst game of the season and scored on their first nine possessions of overtime to pull away for their fifth win in six games.
Green, who averages 25.5 points, finished with 16 on 7-for-21 shooting while being defended mostly by Dexter Strickland.
Green missed a jumper that would have won it in regulation and was held to fewer than 20 points for just the second time this season.
Jarell Eddie added 15 points for the Hokies (11-10, 2-6). They have lost four straight and 10 of 14 since starting 7-0.
