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

Mitchell drove to the rim, jumped up, and put Celtics forward Kristaps Porziņģis on a poster with a highlight jam. The best part of this play was watching Mitchell's Cavaliers teammates react to the dunk.

Ever since he won the Slam Dunk Contest during his rookie season, Donovan Mitchell has established himself as one of the league's best dunkers -- particularly among smaller guards. He added to his resume on Tuesday night with a potential dunk of the year candidate.
