A Cuban amateur national champion, the 28-year-old Barthelemy has yet to taste defeat since turning pro in 2009. Born in Cuba but now fighting out of Las Vegas, he won a super featherweight world title in July of last year by defeating Argenis Mendez in impressive fashion. Most recently he delivered a second round TKO over Angino Perez in March and looks to impress once again when he hits the ring in June.

A former world champion in the lightweight division, the 29-year-old DeMarco steps back into the ring to face the undefeated Barthelemy. Fighting out of Los Mochis, Sinaloa, Mexico, he owns victories over John Molina Jr., Jorge Linares and Lanardo Tyner. He fights for the second time as a pro in the city of Las Vegas on June 21.

The 29-year-old Vasquez has fought professionally since 2012 and served two tours of duty in Iraq as a member of the National Guard. He made it to the semifinals of the 2012 U.S. Olympic trials and won gold at the 2010 and 2011 Armed Forces Boxing Championships. The fighter out of Monessen, Penn., has not lost as a professional and is coming off of a unanimous decision over Emmanuel Lartey in February of this year.

Born in Nigeria, but fighting out of Oxnard, Calif., Omotoso is looking to make it three wins in a row when he battles Vasquez. His most recent victories were both knockouts as he defeated Abraham Alvarez and Eduardo Flores. The 30-year-old made his U.S. debut in 2011 and has racked up a 7-1 record stateside.
