DURHAM, N.C. (AP) -- Mason Plumlee scored 30 points and No. 4 Duke held on to beat North Carolina State 98-85 on Thursday night.
Seth Curry added 26 points and Quinn Cook had 21 for the Blue Devils (20-2, 7-2 Atlantic Coast Conference).
They never trailed, shot 53.8 percent from the field, led by 21 points and held off a Wolfpack rally to claim their fourth straight win.
Richard Howell had 15 of his 23 points in the second half for the Wolfpack (16-7, 5-5), who clawed back in it by making 12 of their first 14 shots of the second half.
But N.C. State -- the preseason favorite in the ACC -- lost its third straight and was denied its first win in Cameron Indoor Stadium since 1995.
