Horacio Accavallo

Horacio Enrique Accavallo (14 October 1934 – 14 September 2022) was an Argentine professional boxer who competed from 1956 until 1967. He held the undisputed World Boxing Association (WBA) and World Boxing Council (WBC) flyweight titles from 1966 to 1968.

Accavallo fought mainly in Argentina. On 1 March 1966, he won the vacant WBA & WBC world flyweight championship by outpointing Katsuyoshi Takayama on 15-round split decision in Tokyo, Japan. Accavallo had been the second contender for the world flyweight title held by Salvatore Burruni. The WBA & WBC had mandated that Burruni fight Hiroyuki Ebihara (the first contender). But Burruni chose to defend the title against Rocky Gattellari. The WBA & WBC stripped the champion of his crown and sanctioned the Accavallo - Katsuyoshi Takayama (the third contender) match for the title. Accavallo retired as the reigning WBA champion after escaping with a controversial 15 round majority decision victory over former world flyweight champion Hiroyuki Ebihara.
