Here is a little biography:
JORGE FERNÁNDEZ — Born on September 28, 1935, in Buenos Aires, Argentina. As a welterweight, he was number one challenger for the world title (1962), as a junior middleweight, Argentinean champion (1966-67); as a middleweight, champion of Argentina (1964-66) and South America (1966-67). One of the most complete Argentinian boxers, with all the resources of the stylist and the power of the most precise and decisive kayoer. In the beginnings of his extended professional career (1953-73), he was unbeaten in 47 fights, with 46 triumphs (31 by KO), until his first defeat, facing the extraordinary puncher Martiniano Pereyra (Points 15), and taking revenge less than a year after. With other important victories against Alfonso Moreno (KO 1), Adalberto Ochoa (KO 4) and Joe Miceli (TKO 7), in 1960 he went to the United States, where he obtained brilliant triumphs over difficult top rivals like Teddy Wright, Isaac Logart, Charley Scott and Denny Moyer (twice). Like with Luis Manuel Rodríguez, Emile Griffith had serious difficulties in his bouts with Jorge, winning in very controversial decisions in the first two fights. In the third, which was for the world welterweight title of Griffith on December 1962, in Las Vegas, Fernández was doing very well on the cards when Emile commited a severe infraction, connecting with a very potent low hit, and when Fernández waited for a technical victory by foul, the referee declared him the loser by TKO: in Nevada, rules didn’t exist for disqualification. Returned to his country, won roundly over fighters like Manuel Álvarez (by KO in 6; Álvarez was winner of Curtis Cokes, in 1962, and with victories over L. C. Morgan, Vicente Derado, Al Urbina and a draw with Nicolino Locche), the European champion Fortunato Manca (Points 10), Billy Collins (Points 10), the Argentinian champion Héctor Mora (Points 10 and TKO in eight), the South American champion Fernando Barreto (TKO 6 and KO 7); his fans and rivals considered him invincible; and his first defeat against Monzón was regarded as an error by the judges and an injustice. The second defeat before Monzón was less controversial than the first, demoralized Jorge, who resolved to retire, though he returned to the ring, fighting in Europe, where he crowned his brilliant career by obtaining the Spanish middleweight championship with a brief victory over Pablo Sánchez (TKO 2, in Zaragoza, in 1973).
