Fernando Javier Vargas (born December 7, 1977) is a retired American boxer of Mexican descent and two-time world champion, who won a bronze medal as an amateur at the 1995 Pan American Games in Mar del Plata. His nicknames include "Ferocious", "The Aztec Warrior" and "El Feroz". Vargas was the youngest fighter to become world light middleweight champion until Saul Alvarez won the vacant WBC belt in March 2011.Some of Fernando's notable wins include victories over former world champions Raúl Márquez, Yori Boy Campas, Ike Quartey, and over Winky Wright. His losses to Oscar De La Hoya, Félix Trinidad, Shane Mosley, and Ricardo Mayorga remain his only career defeats and he is a favorite of American cable TV giant HBO. He's also known for having problems with alcohol (and to a certain extent, drugs) which have been thought to have affected his career at times.Fernando is very good friends with Julio César Chávez; Chavez has been part of Vargas' ring entourage in at least two fights (the fight with Trinidad and the fight with De La Hoya). Chavez was also present when Vargas proposed to his wife (and mother of his 3 boys and 1 girl) Martha Lopez Vargas.
