CHICAGO – J.J. Redick scored 26 points and No. 10 Duke used a smothering defense to rout Valparaiso 93-61 Saturday and give coach Mike Krzyzewski his 699th career win.

Playing in Krzyzewski’s hometown, the Blue Devils took control midway through the first half with a 20-4 run and sailed from there.

Duke (5-0) forced 18 first-half turnovers and built a 48-26 lead in the lopsided game at the United Center.

DeMarcus Nelson scored 17 points, Shelden Williams added 16 and Daniel Ewing 14 as the Blue Devils shot 65 percent for the game, making 36 of 55 field attempts. Dan Oppland paced Valparaiso with 21 points.

Williams started the first-half spurt with a pair of dunks and Redick capped it with a pair of jumpers, the final one a 3-pointer, to make it 25-14.

Redick, who was 8-of-13 from the field, scored 19 points in the first half. And when he hit a jumper, a 3-pointer and two free throws in a personal 7-0 run, Duke was running away at 41-20. Redick’s two free throws with 10:35 left pushed the margin to 30 in the second half.

Valparaiso (0-4) couldn’t solve the Blue Devils’ swarming defense, turning the ball over 21 times for the game, including 10 by freshman point guard Jarryd Loyd, who was starting in place of injured senior Ali Berdiel.

Krzyzewski will become the sixth active Div. 1 coach to reach 700 wins if the Blue Devils beat Toledo on Dec. 12. Now in his 25th season with the Blue Devils, Krzyzewski has 626 wins at Duke.

Duke is now 350-56 against nonconference opponents under Krzyzewski.
