Casimero, a man known for his performances on the road, will be fighting for the third time in Mexico following a split decision loss to Ramon Garicla Hirales back in 2010 and a split decision win over Pedro Guevara. It seems that this time around he doesn't want to leave things in the hands of the judges. Instead it seems that the 24 year old will hunt his third successive stoppage.
For Casimero a win here moves him a step towards becoming a world champion for the second time, having previous held the IBF Light Flyweight title. A win here for Santos however puts him in position to challenge for a world title in what would be his first world title fight. Notably Santos has faced two men who went on to win world titles, Toshiyuki Igarashi and Carlos Cuadras, and beaten a former title challenger, Silvio Olteanu. A win here would be, by far, the biggest win of his career.
