UFC submission match? Is this a normal UFC fight or a grappling only match? Most Sumo are about say like 5'8" and like 300 lbs. A small UFC guy would probably be like 5'5" and 130's lbs. The UFC guy definetly has a great shot at beating the Sumo wrestler. One piece of evidence would be the Royce Gracie (at 6'1" 180 lbs. Brazillian Jiujitsu) vs. Akebono (6'8" 500 lbs. Sumo). This was a MMA match. Everybody knows Gracie as a good MMA fighter. Akebono was a legendary Sumo wrestler. Gracie beat Akebono on the ground (!) with a submission hold in one round! So, there's some proof. Another piece of proof is Keith Hackney (5'11" 200 lbs. White Tiger Kenpo) vs. ? Yarbrough (6'9" 500 lbs. about same size as Akebono. Sumo). Hackney moved around threw some kicks here and there. Sumo had a hard time catching him. Hackney finally throws an overhand palm strike and hits Sumo in the temple. Sumo goes down and Hackney just starts whailing on his head with his fists. Another match with Yarbrough was against an extremely small Japanese MMA fighter in the Pride Fighing Championships. This guy was like 140 lbs., very small. The Japanese just ran around in circles literally for minutes on end, a long time. Sumo got very tired and frustrated trying to catch him. Finally, Sumo fell on the ground somehow and the little Japanese guy fished him off with strikes. So, there is some real life proof of a small MMA fighter beating a big Sumo. Some Sumo fighters are much quicker than those 2 men though. In fact, most Sumo are faster than these men and much smaller. If the Sumo is only trained in Sumo he is toast. The Sumo fighter could maybe get a throw and take the smaller UFC fighter down. That is all the Sumo fighter is trained to do. The UFC/MMA fighter is well trained in many different things. He can box, kick, throw knees, elbows, takedown, throws, armlocks, groundandpound, leglocks, etc. The UFC fighter would also be very quick being so light. He could literaly run circles around Sumo. Sumo comes out trying to palm strike the ufc fighter (Sumo has those puch/palm strikes they use). The ufc fighter stays elusive. He throws kicks and punches, sticks and moves. Sumo is hit hard with those strikes and grows frustrated and discouraged. Finally a strike breaks through and knocks the Sumo wrestler down! The ufc fighter pounces on Sumo and whails away. The Sumo fighter tries to resist but is just being pounded mercilessly. The ufc fighter finally grabs one of Sumo's flailing arms and armbars him for a submission win. In a pure grappling match....A sumo wrestler could probably get the takedown/throw. They are very skilled at doing this, and his size and strength would help him even more. The ufc fighter accepts the takedown. On the ground Sumo has no submissions and is too big too move from position to postion easily. The ufc fighter takes advantage and after a little effort with different positons finds a sumbission. Sumo wrestler loses. Ufc fighters are just waaay too skilled to beat by a pure Sumo wrestler.
