DURHAM, N.C. -- A sign of just how dominant Duke's defense has been so far this season: The latest opponent was relieved to simply escape Cameron Indoor Stadium without setting any records for futility.
The top-ranked Blue Devils routed Miami of Ohio 79-45 on Tuesday night behind 17 points from Seth Curry and a defense that held the RedHawks to 33 percent shooting.
"When you're getting beat pretty thoroughly, first thing is, you realize, 'OK, they're beating us," Miami coach Charlie Coles said. "And the second thought you have is, 'OK, they're beating us pretty good.' And the third thought you have is, 'Uh-oh, are we going to set any records tonight?"
The RedHawks cobbled together just enough offense late to avoid the mark for fewest points scored against a Mike Krzyzewski-coached Duke team. Two of his opponents -- UNC Greensboro in 1997 and Winthrop in 2002 -- managed only 37 points.
Kyrie Irving added 13 points and Mason Plumlee had 10 points and a career-high 14 rebounds for the Blue Devils (2-0), who shot 43 percent from the field, hit 40 percent of their 3-pointers, held a 48-27 rebounding advantage and used two overwhelming runs in the first half to effectively end it by halftime.
Curry, the younger brother of Golden State guard Stephen Curry who sat out last season after transferring from Liberty, was 3 of 4 from 3-point range in his second game in a Duke uniform.
"The past year, it felt like it was a long time, so it was fun to get back out there," Curry said. "I felt a lot more comfortable today because it was the second game back, and I just went out there and was aggressive and knocked down some shots."
His production more than made up for an off night from preseason All-American Kyle Singler, who finished with eight points on 3-of-11 shooting and was held to single-digit scoring for just the second time in 27 games.
"It just shows the balance of our team," Singler said. "We have a lot of weapons."
Krzyzewski moved three wins shy of 800 at Duke and Nolan Smith added 10 points for the Blue Devils, who were barely tested in winning their 12th straight game dating to last season's run through the Atlantic Coast Conference and NCAA tournaments.
They picked up their 21st consecutive victory at home and extended their decade-long winning streak against nonconference teams at Cameron to 79.
But after two wins by an average of 30.5 points, things are about to get much tougher for the reigning national champions: The coming weeks feature matchups against either No. 11 Gonzaga or No. 3 Kansas State in the next stage of this tournament, a visit from No. 2 Michigan State and a neutral-site meeting with No. 16 Butler in a rematch of last season's title game.
"Our schedule is set up to be difficult for us," Krzyzewski said. "But we are improving. The effort, our kids are playing very hard. So we have to keep building."
Miami, the lowest-scoring team in Division I last season, had serious trouble generating good looks against a Duke defense that prides itself on using pressure to maintain a fast pace, create turnovers and turn them into easy transition baskets.
The RedHawks were determined not to let them run, so Coles said they all but abandoned the offensive glass on purpose in an effort to take away the Blue Devils' fast break. As a result, Miami didn't get its first offensive rebound until there were about 5 minutes left in the half and didn't score on consecutive trips downcourt until the final minute before the break. By that point, it was a 20-point game, and the RedHawks didn't get closer than 17 in the second half.
Nick Winbush scored 14 points for the Miami (1-1), which lost its 15th-straight game against ranked opponents. Allen Roberts, who scored a career-high 20 points last time out against Towson, missed all four of his shots and didn't score.
"I knew it would be a tough task for our ball club, because I was wondering before the game -- and I'm serious when I say this -- how many points can we score against these guys?" Coles said. "We're just not ready offensively to do much against a team like Duke. If they would play us tomorrow, it'd be the same thing ... because when you can't get any inside buckets, no post-up buckets, and you got those Plumlees [6-foot-10 brothers Mason and Miles] up there, you're going to struggle."
The Blue Devils shot 46 percent in the first half and used two overwhelming runs to take control. Duke outscored the RedHawks 22-5 during an early 9-minute stretch that pushed their lead into double figures to stay, then made it a 20-point game with a 15-2 burst just before the break. Plumlee followed his missed free throw with a layup that gave the Blue Devils their largest lead of the half, 37-13, with 1:40 left.
Miami hasn't beaten a ranked team since an upset of Boston College in 2001. That was also the RedHawks' most recent victory against a team in the current configuration of the ACC.
