He was defeated in the 1980 147 lb Open division by Pedro Vilella who was a three time New York Golden Gloves Champion.
In April 1982 he defended his world title against Charlie Weir in Johannesburg, South Africa, taking five rounds to knock him out.
Then in July 1982 he fought former world champion Ayub Kalule, whom he stopped in the tenth round in Moore's second title defense.
In 1992, Colombo crime family Caporegime Michael Franzese testified that Moore was handled by himself and other Colombo mobsters, and that although they knew that Moore was in poor physical condition because he had undergone oral surgery just 2 days before the fight, they decided to proceed with the fight due to the profitability of betting on Duran.
[1] Moore won his next two fights, the second in Monte Carlo over Wilfred Benítez but then he was disqualified in the ninth round against Louis Acaries in Paris.
Moore was killed at his home in Holmdel, New Jersey, one evening in early June 1988 when his four-wheel drive vehicle began to roll down the driveway.
