TULSA, OK (May 13, 2014) – BattleGrounds MMA (www.battlegroundsone.com) announced today that it has filled the last remaining spot for O.N.E., its highly-anticipated, one-night, eight-man welterweight (170 pounds) tournament at BOK Center in Tulsa, Okla. on Friday, June 27, with two-time world championship contender and two-time, one-night tournament winner Brock Larson (37-8) of Brainerd, Minn.

The 36-year-old, 5-foot-11 Larson will vie for the single-elimination contest’s $50,000 grand prize amongst a pack of other thirsty challengers, including fellow submission aces Dennis “Superman” Hallman (53-14-2, 1 NC) of Yelm, Wash. and  Cody “AK Kid” McKenzie (15-4) of Spokane, Wash.; undefeated upstart and former NCAA National Wrestling Championship runner-up Chris Honeycutt(4-0) of Fresno, Calif.; Luigi “The Italian Tank” Fioravanti (24-11) of St. Louis, Mo.; Urijah Faber protégé David “Bulletproof” Mitchell (14-4) of Lower Lake, Calif.; Josh “The Beast” Bryant (14-4) of Broken Arrow, Okla.; and Roan “Jucao” Carneiro (16-9) of Atlanta, Ga.

“Brock Larson is amongst the best submission fighters in the world and an incredible addition to our tournament field of world-class talent,” said BattleGrounds MMA President and Olympic wrestling gold medalist Kenny Monday.  “We have on our hands a sensational lineup for BattleGrounds MMA’s first one-night, eight-man tournament, and are going to deliver a very memorable night of action for fans on June 27.”

A 12-year veteran of professional MMA, Larson is also the most seasoned one-night tournament competitor in the BattleGrounds MMA eight-man field, with experience dating back to March 12, 2004 when he overcame Brian Maceachern and Alex Gasson, both by way of armbar submission, in the semifinal and championship stages of a four-man tournament in Minn.

On July 23, 2005, Larson took his first eight-man tournament by storm, finishing three consecutive opponents, beginning with DaMarques Johnson, whom Larson tapped out with a keylock in the third round (1:02) of their quarterfinal stage matchup.  In the semifinal stage, Larson forced Ryan Jensen to tap from an onslaught of punches in the first round (1:39) and, in the championship showdown, Larson again used a keylock to submit Ryan McGivern in the first round (2:09) of battle.

On April 5, 2013, a gritty Larson notched an impressive three-round, unanimous decision win over two-time world champion Melvin Manhoef in Singapore.

Born and raised on a beef farm in Brainerd, Larson developed a strong work ethic during his childhood.  He competed as a high school wrestler before being introduced to Brazilian Jiu-Jitsu and, later, meeting famed world champion Sean Sherk and master trainer Greg Nelson who took Larson under their wings and geared him up for a career in MMA.
