De'Andre Hunter and Evan Mobley combined for 30 points for the Cavaliers, who closed the first quarter on a 27-5 scoring run and never looked back. The Heat, which dropped its sixth straight playoff game at home, were paced by Bam Adebayo with 22 points and nine rebounds. Game 4 is back in Miami on Monday.

The series turns to South Beach. After opening a 2-0 series lead in Cleveland, the Cavaliers made a statement in Game 3, playing without Darius Garland, who missed the game with a sprained toe.

In rolling to a convincing 3-0 lead in this Eastern Conference first-round series, the No. 1 seed Cleveland Cavaliers handed Bam Adebayo and the Miami Heat their worst-ever playoff loss.
