Tyler Hansbrough scored 23 points, including a critical baby hook with 21 seconds to play Tuesday night, and No. 5 North Carolina once again survived a surprising challenge before holding on in a 75-74 victory over host Virginia.

The Tar Heels (23-2, 8-2 Atlantic Coast Conference), coming off a double overtime victory against Clemson on Sunday, got all they could handle from the Cavaliers, who had lost nine of 10 but played nothing like a team in a hopeless free fall.

Virginia (11-12, 1-9), trying to avoid its first 1-9 start in the league since the 1976-77 season, came up short, but not without its best showing in almost a month.

No. 9 Butler 83, Wis.-Milwaukee 75

At Milwaukee, Mike Green scored 10 of his 24 points in overtime and had 13 rebounds and eight assists despite spraining his right ankle to help Butler rally to beat Wisconsin-Milwaukee.

Butler (22-2, 11-2 Horizon League) came in with its highest ranking in school history in the midst of four games in eight days.

No. 19 Purdue 60, No. 10 Michigan State 54

At West Lafayette, Ind., Robbie Hummel scored a career-high 24 points and Purdue beat Michigan State.

Hummel, a freshman, also grabbed 11 rebounds and made 4 of 7 3-pointers.

Freshman guard Kalin Lucas scored a career-high 20 points for Michigan State, and Raymar Morgan scored all 12 of his points in the second half for the Spartans (20-4, 8-3).

No. 23 Louisville 88, DePaul 68

At Rosemont, Ill., Terrence Williams tied a season-high with 22 points and David Padgett set one with 20 to lead Louisville to a win.

It was an easy night for the Cardinals (19-6, 9-3 Big East), who jumped into the Top 25 and shook up the Big East race by beating then-No. 16 Marquette and then-No. 6 Georgetown last week.

No. 24 Vanderbilt 93, Kentucky 52

At Nashville, Tenn., Shan Foster scored 20 points and A.J. Ogilvy added 19 points and 12 rebounds as Vanderbilt handed the NCAA's winningest team one of its worst losses in decades, beating Kentucky.

The Commodores (21-4, 6-4 Southeastern Conference) started a four-game homestand by winning their fourth straight. The only SEC team to open league play with six of their first nine away from home had lost 79-73 in double-overtime at Kentucky on Jan. 12.
