DURHAM, North Carolina (Ticker) -- With a showdown at rival North Carolina on the horizon, No. 6 Duke remained focused on the task at hand.
J.J. Redick scored 29 points and the Blue Devils delivered Miami's NCAA Tournament hopes a critical blow with an easy 83-59 victory in an Atlantic Coast Conference matchup.
Duke knocked off the Tar Heels, 71-70, on February 9 but lost its next two, both on the road, to Maryland and Virginia Tech. If the Blue Devils were looking ahead to Saturday's rematch in Chapel Hill you couldn't tell in this one as they raced out to a big early lead and never let up.
"We played very well tonight," Duke coach Mike Krzyzewski said. "Last week, playing three games in six days, by the time we were coming back from New York, we were worn out. The last couple of days we've practiced great and tonight, we played like we practiced."
Redick scored 18 of his points in the first half as Duke (22-4, 11-4 ACC) raced out to leads of 13-4 and 22-8 on its way to a 44-24 bulge at the break.
"They have the best player in this league on their team, J.J. Redick, and I thought he was outstanding," Miami coach Frank Haith said. "He made a lot of great plays and we never got going."
The Blue Devils connected on 14-of-33 3-pointers, including 6-of-12 from Redick, who hit a few from at least five feet beyond the arc. His six 3-pointers give him an ACC-best 99 for the season.
"We got a couple days off and really had great practices over the last few days," Redick said. "We were ready for this game."
Senior guard Daniel Ewing, playing in his final game at Cameron Indoor Stadium, recorded his first career double-double with 14 points and 10 assists. Center Sheldon Williams chipped in with 14 as well.
"Daniel really is the consummate winner," Krzyzewski said. "This was his 130th game and he's 109 and 21 or somewhere in there. For him to be a part of four teams like that means that he is just a great team player. He's just a kid you want to be around all the time."
"I'll take that any day. It's like a storybook ending," Ewing said. "You couldn't draw it up any other way. Everyone played great, the team played great, and I was able to have my first career double-double."
Miami (16-11, 7-9) was looking for the upset to even its conference record and take itself off the tournament bubble. Instead, the Hurricanes had more turnovers (12) than field goals (10) in the first half and will need a strong showing in next week's ACC Tournament to have a shot at being in the field of 64.
"Joining the ACC, a lot of people didn't think we'd win any games," Haith said. "We're excited about where we are as a team and we've got to get our guys excited about continuing to pay. It's an exciting time. The ACC Tournament - there's no better tournament in the country."
Robert Hite scored 17 points and Guillermo Diaz added 14 for the Hurricanes, who have lost four of their last five.
