Dos Caras was on the Mexican national greco-roman team and he was third at the World Junior Championships in 1997.
He also won the Central American and Caribbean Games in his weight division three times and won a medal at the Pan American Games. Rodríguez was on track to compete at the 2000 Summer Olympics in Sydney, Australia, but due to a lack of funding and support, Mexico did not send a wrestling team that year.
He trained for MMA with the famous Marco Antônio de Lima Ruas. The UFC 7 Tournament Champion considered one of the earliest examples of the complete mixed martial artist, highly skilled in both striking and grappling.
Del Rio's MMA stats are average, but still positive : 9 wins and 5 losses and a lot of wins by submission (7).
I find them quite impressive due to the fact he wasn't a professional and had the guts to fight. I would pay to watch HHH fighting in MMA and I am not sure he would win any fights.
Procop was a killer during this time, Del Rio I salute you.
