ATLANTA (AP) --Iman Shumpert matched his career high with 30 points and Georgia Tech held North Carolina to its fewest points in the Roy Williams era to beat the Tar Heels 78-58 on Sunday night.
Glen Rice also matched his career high with 24 points as Georgia Tech (8-8 overall, 1-2 Atlantic Coast Conference) ended its three-game losing streak.

He blocked two shots and had three steals.
Shumpert and Rice, who had four 3-pointers, were Georgia Tech's only scorers in double figures.

North Carolina's starters returned to the tie game but were still cold, and Georgia Tech led 22-12 when Williams again sent in the backups. North Carolina fans loudly cheered the move.
