Seth Curry led Duke with 25 points, but player of the year candidate Mason Plumlee was held to a season-low four points on 2-of-7 shooting along with two boards before fouling out with 27 seconds left. Cook finished with 18 points and Sulaimon added 16.

Duke, which entered the game as the ACC’s top 3-point shooting team, had one 3-pointer at intermission and was 6-of-19 from beyond the arc. The loss was the Blue Devils’ first in 20 games against unranked opponents.
