DURHAM, N.C. — Ty Lawson helped Tyler Hansbrough make it four in a row at Cameron Indoor Stadium, while keeping himself perfect against North Carolina's most despised rival.
Lawson scored 21 of his 25 points in the second half, and No. 3 North Carolina rallied past No. 6 Duke 101-87 on Wednesday.
Hansbrough scored 17, hitting a late 3-pointer, for the Tar Heels (22-2, 8-2 ACC), who became the first team in nine seasons to hit triple digits vs. Duke. First-place UNC has eight straight conference wins. Florida State is 6-3 in the ACC.
UNC used late runs of 25-11 and 14-0 to take the lead for good, then stretched it to 17. In the process, they ended the Blue Devils' 14-game homecourt winning streak.
Wayne Ellington and Danny Green added 15 points apiece. Green and Hansbrough join former Wake Forest standouts Tim Duncan and Rusty LaRue as the only players to beat Mike Krzyzewski four straight times on the Cameron court that now bears his name.
"Each year it's been different," Hansbrough said. "Our freshman year, no one thought we could come in here and win. … Tonight was one of those things where you didn't want to think about the record. We just wanted to come out and play."
Kyle Singler scored 22 and Jon Scheyer added 20 to lead Duke (20-4, 7-3), which kept up with the uptempo Tar Heels for about 30 minutes before spiraling to its fifth loss in six meetings with its rival.
Gerald Henderson scored 17, but was just 1-for 9 in the second half for the Blue Devils.
Duke led 56-48 early in the second half before North Carolina took command, with Hansbrough hitting a short jumper with just under 18 minutes remaining. That started the Lawson-led 25-11 run.
Then, Lawson gave North Carolina all the separation it needed a short while later, scoring nine of the Tar Heels' 12 straight. His three-point play with 3:42 left made it 88-71.
That came two possessions after Hansbrough pulled up over David McClure and made a 3-pointer with the shot clock about to expire; three seasons ago, Hansbrough hit a 3 at Cameron that he still says is his favorite shot.
That put the Tar Heels well on their way to their first 100-point performance in the rivalry since their double-overtime 102-100 victory in 1995, and made them the first visiting team to win here since they did it last March.
"I told our guys, 'The streak is going to stop at some time,' " UNC coach Roy Williams said. "'Let's just put it off for another year.'"
Duke allowed 100 points for the first time since a 109-100 win vs. Virginia in January 2000.
