The lopsided win was part of the annual Big Ten/ACC Challenge and a rude welcome back to the mainland for the Blue Devils (7-1), who were fresh off winning the Maui Invitational in Hawaii.
Austin Rivers had 22 points for Duke and Mason Plumlee scored 16, but they were the only Blue Devils in double figures and accounted for 15 of the team's 26 field goals.
The Buckeyes (7-0) shot 59.3 percent from the field and won the rebounding battle 32-23.
