In one of the biggest upsets in the history of the sport, Spinks defied his 10-1 underdog odds with bookmakers to prevail after 15 rounds, winning 145–140 and 144–141 on two scorecards while a third went in favour of Ali 143-142. Spinks won gold at the 1976 Olympics in Montreal then rose to greater prominence a little more than 18 months later, given the nod via split decision to stun Ali and claim the WBC, WBA and lineal heavyweight titles.
