Chapel Hill, N.C. — Wayne Ellington scored a season-high 34 points, and North Carolina hit a season-best 16 three-pointers in its sixth straight victory. Tyler Hansbrough had 24 points, and Ty Lawson added 21 for the Tar Heels (20-2, 6-2).

No. 8 Marquette 76, DePaul 61

Rosemont, Ill. — Jerel McNeal scored 26 points, and Marquette beat DePaul for its 12th straight victory, matching its longest winning streak in seven years.
