Hugo Corro began fighting as a professional on August 30, 1973, with a sixth round knockout victory against Gustavo Dieff in the Argentine city of Tunuyan.
Corro won one more fight, and then, he fought ten rounds for the first time in his career, when he defeated Ramon Roberts by a ten-round decision on February 6, 1974.
Corro, however, once again bounced back well, winning his next seven fights by knockout, including a rematch with Juan Carlos Artaza, who was beaten in round ten on September 10.
After two victories over Rodolfo Rosales, Corro had his first fight abroad, boxing against Marcelo Quinones on May 9, 1977, for the South American middleweight title, in Lima, Peru.
Corro followed that win with seven more victories, including title defenses of both his Argentine and his South American middleweight titles, before he got his first opportunity at becoming world champion: on April 22, 1978, Corro became the undisputed world middleweight champion by beating Valdez by a fifteen-round decision in Italy.
[1] He outpointed Harris over fifteen rounds, and then, on November 11, he retained the title in his rematch with Valdez, by a fifteen-round decision at Buenos Aires.
Corro in reality lost his title by only one point, as Antuofermo beat him by a split decision, and each judge had a one-point difference on their scorecard (scores of 146-145, 145-146 and 142-143).
Inspired by the relative success of his much younger brother Osvaldo, a contender during the late 1980s, however, Hugo attempted a comeback during 1988.
After losing by knockout in four rounds to Hugo Antonio Corti on February 17 of 1989, Corro retired from boxing for good.
