CHAPEL HILL, N.C. ? There had been little evidence North Carolina could compete with top-ranked Duke this season.

The Blue Devils proved the obvious as Mike Dunleavy scored 23 points and Jason Williams added 18 Thursday in an 87-58 victory over the Tar Heels the most lopsided game in the series since 1964.

Duke (19-1, 7-1 ACC) beat North Carolina by 14 points in the Smith Center in the 2001 regular-season finale, then bounced the Tar Heels by 26 in the ACC tournament finals. It was more of the same this time as the Blue Devils became the first visiting team to win four straight in the 16-year history of the Smith Center.

Brian Morrison led North Carolina, which matched a season-high with 25 turnovers, with 12 points.

The loss dropped North Carolina (6-12, 2-6) to 1-7 in January. The last time the program lost that many in the month was in 1951.

“The toughest thing now is we’ve got to move on,” North Carolina coach Matt Doherty said. “We really have to put this game behind us.”

No. 3 Maryland 91, No. 8 Virginia 87

Charlottesville, Va. Juan Dixon’s running one-hander with 31 seconds left capped the Terps’ rally from a nine-point deficit with 3:22 to play. Drew Nicholas hit two three-pointers in the closing 13-2 run for Maryland (17-3, 7-1 ACC).

Oregon 91, No. 13 UCLA 62

Eugene, Ore. Frederick Jones scored 26 points and Chris Christoffersen added a career-high 15 rebounds as Oregon claimed its biggest win ever over UCLA. Oregon (16-5, 8-2 Pac-10) stayed in a first-place tie in the league with Southern California. T.J. Cummings had 15 points to lead UCLA (14-6, 6-4), which has lost three of four.

No. 18 Stanford 90, Arizona St. 81

Stanford, Calif. Casey Jacobsen scored 49 points as the Cardinal (13-5, 6-3) beat Arizona State. Jacobsen scored 31 points in the second half, and was 14-of-22 from the field. Only Hank Luisetti with 50 points against Duquesne in 1937 has scored more in a Stanford uniform.

No. 19 Arizona 68, California 58

Berkley, Calif. Jason Gardner scored all but two of his 17 points in the second half and Arizona broke California’s 12-game home winning streak. The Wildcats (14-6, 7-3 Pac-10 Conference) went on a 12-0 run midway through the second half to break a 49-49 tie.

No. 23 USC 64, Oregon St. 51

Corvallis, Ore. Sam Clancy and Brandon Granville both scored 17 points as Southern California beat Oregon State. The Trojans (16-4, 8-2 Pac-10) opened a big first-half lead and coasted the rest of the way. Jimmie Haywood scored 14 points for Oregon State (10-10, 3-7).
