DURHAM, N.C. -- Guard Quinn Cook wanted to take pressure off some of his teammates.
He put it all on Michigan on Tuesday night.
Cook scored all 24 of his points in the second half and helped lead a stubborn defense that guided 10th-ranked Duke to a 79-69 win over No. 22 Michigan on Tuesday night at Cameron Indoor Stadium.
"You see those guys (like teammate Jabari Parker) make shots and for me I want to get them the ball," Cook said. "But other guys have to step up and make his job easier."
Cook did just that in one of the premier matchups of the annual ACC/Big Ten Challenge.
"I think Quinn was fabulous throughout the game even though he didn't score in the first half," Duke coach Mike Krzyzewski said. "He was really in control."
Duke (7-2) did much of its good work at the defensive end. Defense became a priority after the previous home game resulted in a 91-90 victory against Vermont that caused Krzyzewski to make lineup changes.
Michigan trimmed what was a double-digit margin to 34-28 early in the second half and again at 46-40.
Duke reserve guard Andre Dawkins then hit two 3-pointers and scored on a short jumper in slightly more than a two-minute span to push the Blue Devils to a 57-42 edge.
"We ran one thing for him and that was a very critical time for us," Krzyzewski said. "Andre can do that and those were big."
Michigan coach John Beilein said the Wolverines, who were trying to mount a comeback, couldn't afford another Duke player doing such damage.
"They hit huge 3s during that time," he said. "We didn't guard them great, but it wasn't awful. Those are game breakers."
Duke rebounded from last week's loss to Arizona in the final of the NIT Season Tip-Off in New York.
Parker, a freshman forward, scored a season-low 15 points, and forward Rodney Hood pitched in with 14 points.
"The whole focus was we were going to make other people beat us," Beilein said, referring to Parker and Hood. "Cook was sensational."
Cook, who scored 18 of his points in the last 7 1/2 minutes, also provided nine assists.
Guard Caris LeVert scored 24 points for Michigan, which lost for the third time in its past six games. Forward Mitch McGary added 15 points, but guard Nik Stauskas, Michigan's leading scorer, was held to four points, all on free throws.
"Our guys had great attention on defense," Krzyzewski said. "I was so psyched for this game. We needed it badly."
The Wolverines (5-3) improved their shooting in the second half, but their inaccuracy from 3-point range was too much to overtime. Michigan was 1-for-11 from long distance before making their final two 3-point attempts.
Stauskas, who missed the previous game due to an ankle injury, was back in the starting lineup. However, he seemed frustrated at times and missed his only two attempts from the field -- both in the first half. He averaged 20.3 points per game prior to Tuesday.
"They took Nik away," Beilein said. "We guessed that's what they would do. We couldn't get things figured out offensively."
Even a late technical foul assessed to Krzyzewski couldn't turn the tide for the Wolverines.
Guard Tyler Thornton's 3-pointer gave Duke a 32-22 lead at the half. The Blue Devils built a 12-point edge at several junctures before the break.
Hood scored 10 of the Blue Devils' first 25 points.
The first half became a defensive grind at times. Duke even went to center Marshall Plumlee, who sat out entire games, for some early minutes.
It took Michigan nearly 15 minutes to reach double figures in scoring. The Wolverines shot 8-for-26 (30.8 percent) from the field in the half.
With 5:06 left before halftime, Cook picked up a technical foul after throwing the ball at Wolverines forward Jon Horford, who was charged with an initial foul.
