A 105-pound title fight between Stephanie “Macaquinha” Frausto and Diana “Dynamite” Rael headlines the inaugural Women’s Fighting Championship event on May 12th in Casper, Wyoming. MMARising.com confirmed details of the five-round title tilt with a source close to the negotiations tonight.

The all-female fight card also features a rematch between rivals Stephanie “The Scrapper” Skinner and Brittany Nipper, who first faced off in February. Skinner stopped Nipper late in the second round of the action-packed Fight of the Night battle and looks for her second straight win in the rematch.

Frausto (2-4-0) kicked off her pro career with wins in two of her first three bouts in California. She took a massive step up in competition to challenge Lisa Ellis-Ward at Bellator 22 and suffered a quick loss at the hands of her much more experienced opponent, but put on a solid performance in a bout with fellow striker Paulina “Sweetness” Ramirez three months later. Frausto then relocated from California to a new home in Ohio alongside sister Zoila and began training heavily in jiu-jitsu to complement her Muay Thai background. Her new skills were on display in her return to action this January in a highly competitive bout with undefeated 115-pound prospect Ashley “Smashley” Cummins.

Rael (3-2-0) turned pro in 2010 and wasted no time in securing a pair of dominant TKO victories. She stepped back into the cage in early 2011 for a showdown with fellow Colorado native Lacey “The Ladie” Schuckman, but suffered her first loss when Schuckman locked on a fight-ending rear-naked choke late in the opening round. Rael entered hostile territory in August to face local star Angelica Chavez for MMA Fight Pit in New Mexico and picked up her biggest win to date; a well-earned decision after three rounds. Like Frausto, Rael is also looking to rebound from a loss in her most recent fight, which came against the returning Michelle “The Karate Hottie” Waterson in January.

Despite her defeat, Frausto showed marked improvement in the close bout with Cummins; a fight that was mistakenly contested using abbreviated three-minute rounds. Frausto threatened with multiple submissions that forced Cummins to act quickly, and the 21-year-old’s newfound ground skills could prove to be the difference maker against Rael, whose pro defeats have both come via submission. Rael has a solid background in Muay Thai herself, but it was her control on the ground that propelled her to victory against Chavez and she may look to bully her younger opponent on the mat next month.

Frausto and Rael will face off over five, five-minute rounds in the 105-pound WFC title fight.

Women’s Fighting Championship 1 takes place on May 12th in Casper, Wyoming. The all-female card is expected to feature up to a dozen professional and amateur women’s bouts.
