Lake Highlands sophomore Dylan Domizio, 14, trains with Coach Felipe Espinoza at Texas Gladiators Academy. "I teach my fighters how to hurt people," said Espinoza. "Because in the ring, that's what the other guy is trying to do to you." Domizio has won six Golden and four Silver Gloves awards, two Ringside Worlds and was the MMA Teen Fighter of the Year in 2007.
