Duke surged past a fellow No. 1 seed in the N.C.A.A. tournament, Wisconsin, for a 68-63 victory Monday night and its fifth national championship since 1980, when Mike Krzyzewski took over as coach.
The Badgers were playing for a national title for only the second time in their history and the first time since 1941.
The game was taut. Wisconsin at one point had a 9-point lead, but the score at halftime was 31-31.
In the second half, the Badgers committed an uncharacteristic number of fouls and, coming off a tough game against previously undefeated Kentucky, appeared physically spent.
The Duke star Jahlil Okafor was limited by foul trouble, so the Blue Devils surprise hero was another freshman, Grayson Allen, who scored 16 points off the bench.
