CHAPEL HILL, N.C. — Austin Rivers pulled up, launched a high-arcing 3-pointer — and shot No. 10 Duke right back to the top of the Atlantic Coast Conference.

The freshman capped the Blue Devils' furious rally with a buzzer-beater that gave them an 85-84 win over No. 5 North Carolina on Wednesday night — and just might have put their season back on track.

A few days earlier, Duke was reeling after a home loss to Miami — its second defeat in a stretch of three home games.

Just that quickly, the Blue Devils find themselves sharing first place in the league with Florida State and a Tar Heels team they stunned by storming back from 10 points down in the final 3 minutes.

Rivers had 29 points.
