THE richest fight in boxing history produced one of the sport’s most controversial decisions as Sugar Ray Leonard defied the odds and the still formidable skills of middleweight legend Marvelous Marvin Hagler to become the 10th man to win world titles at three different weights. Leonard, the former welterweight and light-middleweight (WBA) champion, ended Hagler’s seven-year spell at the top of the middleweight division with a superbly executed but bitterly disputed split decision win in front of a capacity 15,000 crowd in Las Vegas’ Caesars Stadium and an estimated worldwide TV audience of around 300 million on April 6, 1987.
