Jon Scheyer missed his first nine shots and Nolan Smith missed his first six for the Blue Devils, who shot 31 percent in the opening half to fall behind 37-25. But 22 turnovers doomed the Hurricanes, who attempted only 45 shots to 60 for Duke.
Duke outscored Miami 29-9 to start the second half.
The Blue Devils (22-4, 10-2 Atlantic Coast Conference) increased their league lead with their fifth win in a row. Miami (17-9, 3-9) lost for only the second time in 13 home games.
