#2 Todd Duffee (UFC Fight Night: Mir vs Duffee, July 15, 2015)
Frank Mir followed up his hugely impressive victory over Antonio Silva by claiming "Performance of the Night" honours in his second consecutive fight.
Mir was an underdog against the much younger Duffee, who, according to popular belief, had far superior punching power. Duffee holds the record for the quickest knockout in UFC history, a mere seven seconds. However, it would be Mir whose punching power decided the outcome of the contest.
