Duke's J.J. Redick was more efficient than Indiana's Marco Killingsworth, and he had more help.

Redick scored 29 points and Shelden Williams added 13 before fouling out as No. 1 Duke held off No. 17 Indiana, 75-67, in the ACC/Big Ten Challenge last night in Bloomington, Ind.

Duke is now 7-0 in the showcase event, but had to withstand an outstanding performance by Killingsworth to remain perfect. Greg Paulus also had 13 points for the Blue Devils.

Killingsworth had a career-high 34 points and 10 rebounds, and dominated the middle after getting the Blue Devils' top interior players -- Williams and Josh McRoberts -- into foul trouble early in the second half.

But it wasn't enough.

It was a frantic game from the start with Duke (6-0) uncharacteristically in foul trouble and committing turnovers in bunches.

The Hoosiers (3-1) took advantage in the second half, rallying from a 44-35 halftime deficit, thanks primarily to Killingsworth. His only three sparked an 11-0 run that gave Indiana its first lead at 59-58 with 7 minutes 43 seconds left.

Duke countered with a 9-4 surge to regain control at 67-63 with 4:43 to go, and controlled the contest after that.

* MICHIGAN ST. 88, GEORGIA TECH 86: The Spartans' Paul Davis scored 22 points, and the Yellow Jackets' Zam Fredrick hit the rim on a shot from about 30 feet as time expired, giving No. 13 Michigan State the win in the ACC/Big Ten Challenge in East Lansing, Mich.

Michigan State (4-2) led the entire game, but the Yellow Jackets (2-2) never let the home team get comfortable.

Davis scored 19 of his 22 points in the second half for the Spartans, but his two missed free throws with 4.3 seconds left allowed Fredrick to get off a three-pointer that would've given the young Yellow Jackets a huge win.

* IOWA 45, N.C. STATE 42: In Iowa City, Adam Haluska scored 18 points and the No. 14 Hawkeyes held on for victory over the No. 24 Wolfpack in the final game of the ACC/Big Ten Challenge.

Haluska hit consecutive baskets with less than five minutes to go to put Iowa (5-1) up 41-35. The Wolfpack (5-1) came back and had a final chance to tie, but Ilian Evtimov's desperation three-pointer bounced off the rim just before the buzzer.

* VILLANOVA 86, RIDER 57: Allan Ray scored 21 points and Kyle Lowry added a career-high 20 as the No. 4 Wildcats cruised in Trenton, N.J.

The Wildcats (3-0) had another big game from beyond the three-point line, going 13 for 32, one game after setting a school record with 17 threes against Lehigh.

* MEMPHIS 97, JACKSON ST. 70: Rodney Carney scored 25 points and matched his career-high with six three-pointers to lead the No. 9 Tigers at home
