Dec 1966.

"Horacio Accavallo of Argentina, his right eye swollen shut and his face masked in blood, kept his world flyweight championship Saturday night with a unanimous 15 round decision over Efren (Alacran) Torres of Mexico. The fight, looking much like a street brawl most of the way, kept 25,000 fans howling in Luna Park, the big downtown sports stadium. The 32 year old champion survived a 6th round knockdown from one of Torres murderous right crosses and from the 4th round on kept wiping and blinking blood from his right eye. With the bout just about even after 10 rounds, Accavallo really salted the fight away in the 12th and 13th rounds. He captured the 12th by a big margin with a series of flurries that tore Torres' right ear lobe and reopened a cut under the Mexican's left eye. In the 15th Accavallo expertly flurried in the final minutes."
