DURHAM, N.C. (AP) -- Freshman Austin Rivers scored 17 points to help No. 7 Duke beat Colorado State 87-64 on Wednesday night.
Andre Dawkins added 15 first-half points for the Blue Devils (8-1), who were playing their first game since last week's lopsided loss at Ohio State. Duke had no trouble knocking down shots and finished the game shooting 56 percent, with Dawkins and Mason Plumlee helping the Blue Devils build a 17-point halftime margin.
Dawkins didn't play in the second half after sustaining lower-back spasms late in the first half.
Greg Smith scored 18 points to lead the Rams (5-4), who had stretches of offensive success to keep the game from getting completely out of hand. But Duke ran off 10 straight points to build a double-digit lead in the first half before pushing ahead 47-30 by the break.
