1983-06-16 Roberto Duran w rsc 8 (15) Davey Moore, Madison Square Garden, Manhattan, NYC, New York, USA - WBA. Referee: Ernesto Magana. Thought to be too young and too strong for his veteran challenger, Moore (154) found himself outpunched and outclassed by a man who had got himself into tip-top condition as well as recovering total faith in his ability. With Duran (152½) digging in brutal blows to the body early on it drained Moore, who was never in the fight before being floored in the seventh by a big right. Although the champion somehow made it to the bell the eighth brought him no respite, a rampant Duran smashing him around the ring before the referee came to his rescue on the 2.02 mark.
Supported as champion by the United States Boxing Association, who had set up an international body (USBA/I) back in April (later renamed as the International Boxing Federation in late October), once Moore had lost to Duran and the IBF found that they could not do business with the latter they nominated Mark Medal and Earl Hargrove to meet for their version of the title.
After Duran relinquished the WBA version of the title in June 1984 to challenge Marvin Hagler for the world middleweight crown crown, Mike McCallum and Sean Mannion were matched to find a new champion.
