Jabari Parker had 17 points and a season-high 15 rebounds on Wednesday night, and No. 18 Duke earned its first league road win of the season by beating Miami 67-46.
Parker helped the Blue Devils to a 42-28 advantage on the boards, which allowed them to overcome a poor shooting night. Duke outscored Miami 22-7 on second-chance points.
A sellout crowd included Kobe Bryant, LeBron James and Dwyane Wade, all seated in the front row. Bryant was at the other end of the court from the Heat stars.
The Blue Devils (15-4, 4-2 Atlantic Coast Conference) avenged a 27-point loss the last time they played in Coral Gables. That was a year ago, when Duke was ranked No. 1.
Defending conference champion Miami (10-8, 2-4) remained winless in three league games at home.
