Virginia's J.R. Reynolds (2) tugs on Sean Singletary's jersey as they celebrate Singletary's winning basket against Duke. The Cavaliers defeated the Blue Devils, 68-66 in overtime, Thursday in Charlottesville, Va.

Charlottesville, Va. ? Sean Singletary had already tied the game with 24 seconds left in regulation, his first basket in almost 16.

Hitting the game-winner late in overtime almost seemed routine – even if the shot was anything but ordinary.

Singletary hit a falling, one-handed floater with a second left in overtime Thursday night, lifting comeback-crazy Virginia past No. 8 Duke 68-66.

“I got bumped and to catch my balance, I had to get off my feet,” Singletary said of the shot over 6-foot-10 Josh McRoberts from the right side of the basket.

The Cavaliers (14-6, 6-2 Atlantic Coast Conference), who trailed 59-51 with 3:42 left in regulation, pulled off their second highly improbable comeback in five days.

On Saturday at Clemson, they erased a 16-point deficit in the last nine minutes, winning on a tip-in by Jason Cain with 15.5 seconds left. And this time, J.R. Reynolds scored the first eight points in a 10-2 run to end regulation, and Singletary tied it.

The overtime ending left even Duke’s players shaking their heads. The Blue Devils (18-4, 5-3) had won nine in a row against Virginia and led almost the entire night.

“We had some shots, including the one at the end of regulation, that were great shots. We just didn’t knock them down,” Duke coach Mike Krzyzewski said.

It was Virginia’s fifth victory in a row, and broke their tie with the Blue Devils for fourth place in the ACC at the midpoint of the conference schedule.

The Blue Devils had their five-game conference winning streak snapped.

Singletary scored 17 despite making only 6 of 16 shots, and Mamadi Diane had 14.

No. 5 UCLA 69, No. 9 Oregon 57

Los Angeles – Arron Afflalo scored 17 points, and UCLA shot 57 percent in gaining sole possession of first place in the Pac-10.

The Bruins have won 16 consecutive games at Pauley Pavilion. UCLA and the Ducks came in tied atop the conference.

Bryce Taylor scored 17 points to lead Oregon, off to its best record in 80 years.

No. 18 Washington State 72, No. 20 Arizona 66

Tucson, Ariz. – Ivory Clark scored 18 points and Washington State swept the season series from Arizona for the first time since 1983.

Washington State won for only the fourth time in 48 games against Arizona coach Lute Olson.

Chase Budinger scored 19 points and Mustafa Shakur added 13 for Arizona, which lost for the sixth time in eight games.
