Duke (19-4, 9-4 Atlantic Coast Conference), coming off consecutive losses for only the fourth time in the past eight seasons, had its way with the Demon Deacons in the second half. After trailing by two at the break, the Blue Devils shot 61 percent in the final 20 minutes to reach their highest point total of the season.

"It was as good as our offense has looked all year, and it wasn't one guy or just me," Redick said. "It was everybody."

Chris Paul had 27 points and Trent Strickland scored 17 for Wake Forest (22-4, 10-3), which fell out of a first-place tie with North Carolina.

Duke center Shelden Williams more than held his own in the matchup with Eric Williams, finishing with 12 points, nine rebounds and four blocks. And Melchionni, a junior who played very little during his first two seasons, came up with big play after big play when the Blue Devils needed it most.

He came in averaging only 6.8 points a game, but beat that total during a 90-second span of the second half. The left-hander swished a 3-pointer for a five-point lead, jumped in the passing lane for a steal that led to his own dunk, then spun in the paint for a short jumper.

No. 10 Arizona 91, Oregon St. 70: Salim Stoudamire sank a school record nine 3-pointers and scored 31 points in his final home game, and the Wildcats (23-4, 13-2 Pac-10) won their sixth in a row by routing the Beavers (14-11, 6-8).

No. 12 Louisville 84, Saint Louis 66: Taquan Dean hit five 3-pointers for 15 points and the Cardinals (23-4, 11-2 Conference USA) beat the Billikens (7-18, 4-8) at Louisville, Ky.
