Mario Sperry needs no introduction (but we’ll give him one anyways). Sperry is a legendary Brazilian heavyweight MMA champion that specializes in jiu-jitsu, ground-fighting and grappling. He is a co-founder of the Brazilian Top Team, a team that has produced an array of world-class fighters such as Vitor Belfort, the Nogueira brothers, Murilo Bustamente and Ricardo Arona. Sperry’s pedigree is also second-to-none; he was trained by one of the Gracie’s. True to his nickname “The Zen Machine”, he is undoubtedly a machine. Amongst his victims in the octagon are Hirotaka Yokoi, and the infamous Igor Vovchanchyn, to name a few.
