This was a tough one to choose as both Sergei Pavlovich and Roman Dolidze showed fans their mettle and had massive nights. Ultimately though, the award goes to Dolidze. He went from unranked to a top-10 contender that the whole division needs to be wary of overnight.
Dolidze started his UFC career off right with a 1st-round knockout of Khadis Ibragimov but had three somewhat lackluster performances after against John Allan, Trevin Giles, and Laureano Staropoli.
The Georgian took a year off and came back reinvented, finishing three opponents in a row now. It began with his 1st-round knockout over Kyle Daukaus at UFC Austin earlier this year, then he tore Phil Hawes' knee apart in a leg lock and slept him with a nasty 3-punch combo.
Now we find ourselves in the present day, and he's just earned the biggest of them all against Jack Hermansson at UFC Orlando. He finished Jack with one of the most unique and painful-looking calf-slicer mounts to ground and pound TKOs in UFC history.
Dolidze will find himself in the Middleweight division's top 10 next week and has a name in mind for his next fight, Khamzat Chimaev.
