WASHINGTON (Ticker) -- After a poor start, J.J. Redick found his shooting touch down the stretch.
Redick scored 12 of his 15 points in the second half as fifth-ranked Duke overcame a poor shooting performance for a 76-64 victory over Virginia in the quarterfinals of the Atlantic Coast Conference tournament.
The Blue Devils (23-5), in search of their sixth tournament title in the last seven years, will face North Carolina State in the semifinals Saturday. The Blue Devils beat the Wolfpack, 86-74, in Raleigh on January 13 in the only regular-season meeting between the schools.
"When we played them the first time, they were going through some injuries and illnesses and they weren't a full team," said Redick about the Wolfpack, who upset third-ranked Wake Forest, 81-65, earlier Friday. "Right now they are playing as hungry as any team in the conference."
With both teams shooting under 40 percent for the game, the Blue Devils took control of the contest by dominating the boards, 54-30. They had 23 offensive rebounds compared to just eight for the Cavaliers.
"I thought the difference in the game was our rebounding," Duke coach Mike Krzyzewski said. "For us to outrebound them by 24 is big and a lot of that had to do with our perimeter rebounding. Lee (Melchionni) had nine rebounds, Reggie (Love) had eight and DeMarcus (Nelson) really rebounded (with five)."
Duke, which shot 37 percent (24-of-65) for the game, took a 40-28 lead at the break. But Redick scored just two points on 1-of-10 shooting, missing seven of his first eight 3-pointers.
The Cavaliers (14-15) opened the second half with an 11-3 run and closed within 45-43 on two free throws by Sean Singletary with 14:39 to play. Redick answered with a 3-pointer and Shelden Williams made a layup to push the lead to 50-43 with 13:10 remaining.
Redick added another 3-pointer four minutes later and sank a jumper for a 62-52 advantage with 7:46 left.
"We played well but we just ran out of energy," said Singletary, whose team missed four of its last 11 shots in the final seven-plus minutes. "We don't have a lot of depth. It hurt us throughout the year."
With Redick struggling, Melchionni took charge in the first half by scoring 14 of his 16 points. He hit two 3-pointers during a 16-4 run that closed the first half, shooting 4-of-7 from the arc in the opening 20 minutes.
"J.J. is such an unbelievable shooter," Melchionni said. "He attracts so much attention that even on off nights people still flock to him. I just try to play off of him and I get open shots off of him." Daniel Ewing finished with 16 points and six assists and Williams scored 10 points and pulled down 10 rebounds for Duke, which has not lost in its opener of the conference tournament since 1997.
Singletary scored 16 points, Devin Smith 13 and J.R. Reynolds 11 for Virginia, which also struggled from the floor, shooting 38 percent (22-of-58).
