Two more high-level grapplers are set to battle for the KASAI World Featherweight belt on November 10th at Manhattan Center’s Hammerstein Ballroom.


October 1– New York City, NY – KASAI Elite Grappling Championships (KASAI) today confirms that Geo Martinez and Ethen Crelinsten will compete in its World Featherweight Championship Tournament at ‘KASAI Pro 4’ on Saturday, November 10 at Manhattan Center’s Hammerstein Ballroom.

KASAI CEO Rich Byrne commented “we are excited to add Geo and Ethan to the tournament. Both are highly accomplished competitors who bring an element of unpredictability to the stage because of their reputations for executing deadly submissions.”

Geo Martinez is a two-time ADCC combatant and a three-time EBI champion, having won tournaments at both 145lbs and 135lbs. An accomplished no-gi black belt under the 10th Planet Jiu-Jitsu academy system, ‘Freakazoid’ has won 77 percent of his competitive wins by way of submission, including several by calf-slicer submission.

Ethan Crelinsten of Tristar Gym/Renzo Gracie NYC has been on a tear. He won the 2017 ADCC West Coast North American Trials. Since then he’s competed at Sapateiro, the Onnit, Global Grappling League, and Toro Cup. Crelinsten qualified for the tournament by winning his match at ‘KASAI Pro 3’ against Junny Ocasio via rear naked choke.

In addition to Martinez and Crelinsten, other names competing in KASAI’s eight-man no-gi tournament at 145lbs (65.77kg) include Gianni Grippo, Paulo Miyao, John Calestine, and Bruno Frazatto. ‘KASAI Pro 4’ will also feature two explosive superfights.
