BLOOMINGTON, Ind. — J.J. Redick responded to Indiana's challenge the way he always does — by making big shots.

Redick scored 29 points, including six during a decisive late stretch, to lead No. 1 Duke past No. 17 Indiana on Wednesday in one of the ACC/Big Ten Challenge's marquee matchups.

"I thought our kids were stronger," coach Mike Krzyzewski said. "We went down on three straight possessions late and gave the ball to our two seniors, Redick and (Shelden) Williams, and they scored baskets."

Duke (6-0) played an uncharacteristically erratic game to stay undefeated. Its top two post players, Williams and Josh McRoberts, spent much of the second half in foul trouble and the Blue Devils finished with 19 turnovers.

They also couldn't stop Indiana forward Marco Killingsworth, who finished with a career-high 34 points. Killingsworth did everything, hitting 15-of-20 shots, grabbing 10 rebounds, blocking two shots and continually drew fouls against Williams and McRoberts. His only 3-pointer of the game came during an 11-0 second-half run that gave Indiana its first lead at 59-58.

But Redick's supporting cast was stronger.

Williams finished with 13 points and nine rebounds. Greg Paulus added 13 points and Lee Melchionni had 12 for Duke.

The only other Hoosier in double figures was Marshall Strickland with 11.

Duke improved to 7-0 in the ACC/Big Ten Challenge, and combined with Wednesday's other results, gave the ACC its seventh consecutive series win. This year, the ACC won 6-of-11 games played between two of the nation's strongest conferences.

The game also lived up to the hype. Indiana fans turned Assembly Hall into a sea of white, rather than its usual red, and were primed for an upset as they started chanting more than 20 minutes before tip-off.

The noise rattled both teams.

Indiana (3-1) threw the ball away four times in the first 3:09 and quickly found itself in a 16-2 deficit. The Hoosiers got as close as four in the first half and trailed 58-48 midway through the second half when Killingsworth sparked Indiana's big spurt, which ended with his one-handed dunk.

"They were pressing our guards and they were staying on our guys even when they drove," Killingsworth said. "They probably felt `Let Killingsworth beat you.'"

He nearly did.

But Redick stabilized the Blue Devils.

He helped free Williams for three straight baskets late, then hit a 3-pointer to close a 9-4 run that gave Duke a 67-63 lead with 4:43 left. Two minutes later, he drove in for a nifty layup and completed the three-point play to make it 70-65.

Indiana never got closer than three the rest of the way.

Duke avoided a second straight upset to the Hoosiers, who won the last meeting in the 2002 regional semifinals at Lexington, Ky. The Blue Devils were also ranked No. 1 then.

"Wow! What a great game," Krzyzewski said. "J.J. just refuses to lose. He's one of those amazing players. That kid is really, really tough."
