CHAPEL HILL, N.C. ? Tyler Hansbrough started and ended North Carolina’s game-breaking 17-2 run in the second half and the seventh-ranked Tar Heels went on to a 98-89 victory over No. 3 Ohio State on Wednesday night in the ACC-Big Ten Challenge.

In a game featuring two of the country’s top freshman classes – with Greg Oden, the best of the bunch, sitting on the Ohio State bench in street clothes with a towel around his neck – Hansbrough, a preseason All-America as a sophomore took over down low.

The 6-foot-9 forward was the key inside as the Tar Heels (5-1) were able to overcome an incredible 3-point shooting performance by the Buckeyes (6-1), who were playing outside the Columbus city limits for the first time this season.

Hansbrough finished with 21 points and 14 rebounds, and freshman Wayne Ellington added 19 for North Carolina.

Ron Lewis had 30 points for Ohio State, which finished 13-for-26 from 3-point range.

The ACC had already clinched the 11-game challenge series for the eighth time in as many meetings.
