Roberto Duran, the 44-year-old four-times former world champion from Panama, stopped the American Wilbur Garst with 46 seconds of the fourth round remaining in a scheduled 10-round super-middleweight fight in Fort Lauderdale, Florida, on Thursday.
Duran won the first of his world titles in 1972, when he knocked out Britain's Ken Buchanan for the lightweight championship. He later held welterweight, junior middleweight and middleweight titles.
Duran, who lives in Miami, dominated Garst with jabs and straight rights as well as telling blows to the body. Garst landed some rights to the head but not enough to overcome Duran. "He hit me with some good shots, but I just had to measure him right," Duran said.
Duran's record is 97 wins and 11 defeats, with 67 knock outs. Garst, from Tulsa, is 17-4.
