Middleweight (≤160 pounds), Men

Date	21 – 24 August 1920
Status	Olympic
Location	Feestzaal, Koninklijke Zoölogische Maatschappij, Antwerpen
Participants	17 from 9 countries
Format	Single elimination tournament.

Harry Mallin ran through the North Americans to win his gold medal, defeating Americans in the first two rounds, and Canadians in the semi-final and final. In the second round against Samuel Lagonia, Lagonia was disqualified for clinching in the second round. The U.S. report stated that the decision was grossly unfair and that it was Mallin who should have been disqualified. However, the Belgian newspapers stated that Mallin was well ahead at the time of the disqualification, and that Lagonia was stalling a great deal.

Mallin is considered the greatest amateur boxer ever from England. He was apparently never beaten in the ring. In 1924, he returned to the Olympics and became the first boxer to defend an Olympic championship. Lagonia was U.S. AAU Champion from 1919-1921. The 1919 Inter-Allied Champion in this class competed at Antwerp, but Eddie Eagan moved up to the light-heavyweight class.
