DURHAM, N.C. — Freshman Kyrie Irving had a season-high 31 points and No. 1 Duke beat No. 6 Michigan State 84-79 Wednesday night in the marquee matchup of the ACC/Big Ten Challenge.
Nolan Smith added 17 points and Kyle Singler 15 for the Blue Devils (7-0), who shot 47 percent, turned 20 turnovers into 28 points, used a 12-2 spurt midway through the second half to take a double-figure lead and hit 9 of 12 free throws in the final 1:15.
Korie Lucious scored 20 and Draymond Green had 10 of his 16 in the final minute for the Spartans (5-2), who hit one field goal in a seven-minute stretch that coincided with Duke's run but otherwise hung tight with the reigning national champions.
Ultimately, Duke found a way to win its 17th straight game, its 23rd straight at Cameron Indoor Stadium and its NCAA-best 81st straight nonconference home game.
Mike Krzyzewski claimed the 875th victory of his coaching career to move one behind Adolph Rupp, who's third all-time.
For much of the way, little came easy for Duke. Michigan State closed to 69-64 on Durrell Summers' dunk with 3½ minutes left before Singler stuck back Irving's miss. Mason Plumlee hit two free throws to push it to 73-64 with 2:22 left.
