Talib Zanna had 19 points and a career-high 21 rebounds to help Pittsburgh beat No. 15 North Carolina 80-75 in the Atlantic Coast Conference tournament quarterfinals Friday.
James Robinson also scored a career-best 19 points for the fifth-seeded Panthers (25-8), who used a dominating start to build a huge lead before having to hold off a late rally by the fourth-seeded Tar Heels (23-9).
Pittsburgh led by 20 points with 7:22 left before UNC's frantic comeback behind Marcus Paige, who scored 20 of his 27 points after halftime before fouling out with 25.4 seconds left.
UNC got it to 78-75 on Nate Britt's jumper with 11.4 seconds left but couldn't complete the comeback. James Robinson knocked down two free throws to make it a two-possession game again right after Britt's score, then Lamar Patterson rebounded a hurried 3-pointer by James Michael McAdoo with 4.3 seconds left to essentially seal it.
