Adolfo Viruet won two New York Golden Gloves Championships. He won the 1968 featherweight title in the sub-novice division and the 1969 featherweight title in the open division. Viruet and his older brother, Edwin Viruet, were supposed to box each other in the 1969 final, but it was decided that the brothers should not have to fight each other, and they were declared co-champions. According to an article in The Ring, both brothers finished their amateur careers with 18-0 records.
Edwin Viruet also fought Duran. He lost by a ten-round unanimous decision in 1975 and by a fifteen-round unanimous decision for the World Lightweight Championship in 1977.
Adolfo was inducted into the New Jersey Boxing Hall of Fame in 1995.
