GREENSBORO, N.C. -

P.J. Hairston scored 21 points to help North Carolina beat Florida State 83-62 on Friday night in the Atlantic Coast Conference tournament quarterfinals.
   
Hairston hit five 3-pointers before leaving late in the game with a cut on his left hand, while Reggie Bullock added 17 points for the third-seeded Tar Heels (23-9). They took control with a 13-0 run early in the second half, hit 10 3s and also scored 27 points off 18 turnovers to beat the reigning champion Seminoles in a rematch of last season's championship game.
   
The Tar Heels reached Saturday's semifinals to face seventh-seeded Maryland, which upset second-ranked Duke earlier Friday. UNC has reached the past two finals and is trying for its first title since 2008.
   
Michael Snaer scored 20 for sixth-seeded Florida State (18-15), which lost all three meetings with the Tar Heels this season with the last two coming by 21 points each.
