2) Marcus Aurelio vs Ryan Roberts – 0:16

Marcus Aurelio might not be in the fight game any more but the Brazilian had several quality wins in his career.

The now 47-year-old is doing a lot of Jiu jitsu work outside of the Octagon and also motion capture parts for movies and shows.

However, he also has one of the fastest submission wins in the history of the UFC. Aurelio was up against Ryan Roberts and got the win in 16 seconds thanks to an armbar.

Aurelio finished his MMA career with 22 wins and 10 losses but his 16-second win remains one of the best.
