Tyus Jones scored 22 points, Rasheed Sulaimon added 14 and No. 4 Duke shot 65 percent to beat No. 2 Wisconsin 80-70 on Wednesday night in a highly anticipated matchup of college basketball heavyweights.

With 17 points, Wisconsin senior Frank Kaminsky outscored Duke freshman Jahlil Okafor (13 points) in a test for the two of the nation's top big men.

But it was another touted freshman, Jones, who helped open things up for the Blue Devils (8-0) in the second half. The lightning-quick guard beat defenders into the lane and added two 3-pointers.

Jones followed a transition layup with an assist on Amile Jefferson's jumper to cap a 6-0 run that gave Duke a 69-60 lead with about 3 minutes left against the Badgers (7-1).
