After he produced a stunning show at the Slam Dunk Contest on Saturday night, it's surprising that Donovan Mitchell wasn't invited to take part initially.The Utah Jazz rookie has enjoyed several highlight dunks this season as he's taken the league by storm but was somehow not part of the list of players asked to feature.Only an injury to two-time participant Aaron Gordon gave Mitchell the opportunity to showcase his ridiculous athleticism in L.A. and he didn't disappoint.He was crowned as the champion after he performed a throwback dunk in honour of the legendary Vince Carter while wearing his classic purple Toronto Raptors jersey.The 21-year-old was the star of the show but the dunk of the night certainly belonged to Dallas Mavericks point guard Dennis Smith Jr.Smith produced a difficult 360 where he went between his legs and switched from his right hand to his left, and threw it down.It was a tremendous dunk that earned the first 50 of the night from the judges.Despite this impressive flush, however, it wasn't enough to get the youngster into the final because of his score from the first round.The 20-year-old got off to a rocky start as he attempted 360-degree windmill from the right-hand side of the court but came up short on his first try.He decided to ditch this and played it safe by going to the left-hand side and performing a double-pump reverse for his second attempt.It was still a nice dunk but it only earned him a score of 39 from the judges.

As a result, Smith didn't make it to the final round and he took to Twitter after the event to express his displeasure.

Fellow contestant Victor Oladipo missed all three of his attempts when he tried an ambitious off-the-bounce, two-handed reverse windmill but managed to get a score of 31.

Smith tweeted his confusion at how his double-pump reverse got him a 39 and Oladipo got 31 without actually making any of his dunks.

His frustrations didn't end there. After the Mavericks posted a video of his 50-point dunk on Instagram, he commented by saying: "Highway robbery".

The rookie does appear to have a legitimate argument as he shouldn't be eight points ahead of a player who didn't connect on any of his tries.

With scores of 93 and 98, respectively, it was Mitchell and Larry Nance Jr. who contested the final where the Jazz sensation came out on top.
