Duke Stuns North Carolina at the Buzzer CHAPEL HILL, N.C. (AP) - Freshman Austin Rivers buried a 3-pointer at the horn to give No. 10 Duke an 85-84 win over No. 5 North Carolina on Wednesday night. Rivers scored a season-high 29 points and hit six 3s, though the last will certainly live on in the lore on the fierce rivalry. With the Blue Devils (20-4, 7-2) trailing by two, Rivers launched a 3 over 7-footer Tyler Zeller from the right wing. The ball swished through the net, sending Rivers running down the court in celebration while the rest of his teammates gave chase before mobbing him in front of a stunned UNC crowd. Rivers' 3 capped a wild rally for the Blue Devils, who trailed by 10 points with about 2½ minutes left. Harrison Barnes scored 25 points for the Tar Heels (20-4, 7-2), while Zeller finished with 23 points and 11 rebounds. But Zeller missed a free throw with 13.9 seconds left, setting up Rivers' winning shot.
