DURHAM, N.C. -- Kyle Singler had career highs of 30 points and eight 3-pointers to lead No. 10 Duke past No. 21 Georgia Tech 86-67 on Thursday night.
Jon Scheyer added 21 points for the Blue Devils (18-4, 6-2), who were strong inside and outside -- hitting nearly 67 percent of their 3s and dominating Georgia Tech's foul-plagued front line.
Duke held a 40-32 rebounding edge and remained atop the Atlantic Coast Conference by claiming an easy win in a matchup of the league's only two ranked teams.
Zachery Peacock scored the Yellow Jackets' first 11 points, but didn't score after that. Leading scorers Gani Lawal, a Norcross grad, and Derrick Favors were in foul trouble for Georgia Tech (16-6, 4-4).
Nolan Smith had 14 points for Duke, which led by double figures for the entire second half in bouncing back from a loss at Georgetown and avenging last month's 71-67 loss to Georgia Tech.
The Blue Devils shot nearly 45 percent against the nation's fourth-best field-goal percentage defense, and Singler -- who was just 2-for-13 in that defeat in Atlanta -- nearly did it all this time.
He finished 8-for-10 from 3-point range, scored 20 points in the final 20 minutes and shook off a pesky right wrist sprain to lead the way in a dominating second half that carried the Blue Devils to their 15th straight win at Cameron Indoor Stadium.
They were a late Georgia Tech free throw away from their 11th 20-point win at home this season, and entered outscoring their visitors by an average of 28.9 points.
Singler hit his first three 3s of the second half to help push Duke's lead well into the teens. Then, he helped the Blue Devils take their first 20-point lead when he took off downcourt after his steal and dumped a behind-the-back pass to Smith, whose layup attempt was swatted away on the rim and Brian Oliver was called for goaltending to make it 63-43 with 111/2 minutes left.
