HARRY Simon, who recently defended his World Boxing Organisation light middleweight title with a third round knock-out of Britain’s Kevin Lueshing, has the potential to dominate the light middleweight ranking for the next couple of years. So says Bert Blewett, a South African boxing expert and editor of the magazine, Boxing World and Simon’s trainer Brian Mitchell. Simon’s professional record of 18 wins, 15 knockouts and no losses compares very well to other light middleweight champions of various boxing associations. The World Boxing Association’s champion, David Reid of the United States is a former Olympic champion and unbeaten after 12 fights. The World Boxing Council’s champion Francisco Castillo of Spain doesn’t have too an impressive record, having lost four of his 48 fights, while the International Boxing Federation’s champion Fernando Vargas of the United States is still unbeaten after 16 fights.
