The Boston Celtics went to Cleveland to take on Donovan Mitchell and the first-place Cavaliers Tuesday night. Mitchell got to work early by entering his name into the ring for the best dunk of the year.

Mitchell's dunk over Kristaps Porzingis failed to set the tone for the Cavaliers, who fell at home to the Celtics.

Nearly five minutes into the contest, the Cleveland Cavaliers guard attacked the rim after splitting two defenders at the top of the key.
