DURHAM, N.C. (AP) — Grayson Allen finally found some open lanes to the basket, and he burst through them.
All those drives added up to the highest-scoring game of his career.
A.J. Spencer scored 20 points and Noah Blackwell had career highs of 19 points and four 3-pointers for the 49ers (6-9).
Allen was 8 of 15 from the field and kept drawing contact and getting to the foul line, hitting 15 of 17 from there while surpassing his previous career-best of 32 points set against Georgetown last month in New York.
The Blue Devils hit 11 of 12 free throws during a 2½-minute stretch early in the burst before Allen dunked on Spencer and Thornton capped the run with a contested jumper that made it 51-38 with 17½ minutes to play.
The Cameron Crazies chanted Marshall Plumlee's name after he came up huge at both ends of the floor in the span of a few seconds.
Maryland transfer Nick Faust finished with 10 points in his first game at Cameron Indoor Stadium since February 2014, when Duke beat the Terrapins 69-67 on a missed hook shot at the buzzer by Maryland.
