TALLAHASSEE — It ended up being a day and evening for coach Leonard Hamilton and Florida State to gut things out. Hamilton had surgery to remove kidney stones Wednesday morning. Less than 12 hours later he was on the sidelines as his 24th-ranked Seminoles held on for an 81-80 victory over No. 12 North Carolina. "I feel mission accomplished," Hamilton said. "The last 36 hours have been tough for me. I’ve had tougher things to overcome, maybe not as painful. This makes the pain worth it." FSU (12-2, 1-1 ACC) led most of the game, including the final 8:12. But the Seminoles nearly squandered it as they didn’t make a field goal in the last 2:57 and missed their last four free throws. The Tar Heels (12-3, 1-1) got within 81-80 with 30 seconds left when Joel Berry made a 3. After Phil Cofer missed both free throws, UNC had a chance to win. Berry drove the lane and missed a jumper that was rebounded by Terance Mann. Mann missed his free throws with 1.7 seconds remaining, but UNC didn’t get a shot off, allowing FSU to snap a seven-game losing streak to the Heels. "We just like playing with each other so much. I feel like we’re able to call each other out on plays, we can get on each other and not let it affect us," said Walker, who scored 18."They attacked so much more effectively. I liked our kids making a comeback," North Carolina coach Roy Williams said.Braian Angola led FSU with 20 points and Mann added 17. The Seminoles extended their home winning streak to 28, third longest in Division I. Berry led the Heels with 28 points, including 20 in the second half after they trailed 51-40 at halftime.Up next for FSU: at No. 15 Miami on Saturday.BULLS FALL: Kentrell Barkley scored 16 to help East Carolina upend USF 67-65 at the Sun Dome.
