Leotis Martin (March 10, 1939 – November 20, 1995) was an American boxing, he was the inaugural NABF Heavyweight Champion. A fairly-skilled heavyweight and a good punch, he beat rated contenders Alvin Lewis, Thad Spencer, Karl Mildenberger, and Sonny Banks, but is perhaps best known for his knockout victory over former-Heavyweight Champion, Sonny Liston. Unfortunately, Martin was forced to retire shortly after the Liston win due to a detached retina. The Ring Magazine listed Martin 68th on its list of the "100-Greatest-Punchers of all Time".
Although Martin was selected for the WBA title elimination tournament, he was matched, in his first fight, against the ultimate tournament winner Jimmy Ellis. The two fought in the Houston Astrodome on August 5, 1967. Ellis, as was his style at the time, came out sharp, trying to score an early knockout with his sneaky-fast and dangerous right hand. Although unable to knock Martin out, Ellis inflicted a nasty cut on the inside of Martin's mouth, which ultimately caused the fight to be stopped in the ninth round. Scoring was around even at that point. Many had predicted Martin might win the elimination series. Martin had campaigned for a contest with fellow Philadelphian Joe Frazier, but it never happened, mainly due to Martin's loss to Bonavena, who got the Frazier match instead.
Martin rebounded from the Ellis defeat by traveling to Germany to knock out German and European heavyweight champion Karl Mildenberger in seven rounds. Martin appeared to be back in contention for a title shot when he dropped a decision to California heavyweight Henry Clark (record 14-3-2). He then came back from that defeat to upset and knock out Thad Spencer in nine rounds. His title quest, however, was again derailed when Martin travelled to Argentina to meet Oscar Bonavena in his home town of Buenos Aires, where he lost by decision. Bonavena went on to fight Frazier for the world title.
After the Bonavena loss, Martin put together a four-fight win streak, including two wins over Detroit hometown favorite Al "Blue" Lewis. These fine efforts landed him a match with veteran former champion Sonny Liston on December 6, 1969. Liston had resumed boxing after his two stunning losses to Muhammad Ali, and had run off a winning streak of 14 fights with 13 knockouts. Although slowed by age, Liston was still a feared heavyweight.
Martin, who formerly had been Liston's sparring partner, devised a simple fight plan. Rather than attempting to slug with the bigger and heavier Liston, Martin stayed away from him, boxing and waiting for the older man to tire. Despite a close call in the fourth round when Liston caught him with a booming left hook that knocked Martin down, Martin seemed to get stronger with every passing round while Liston weakened. Finally, in the ninth round, Martin hit Liston with a powerful combination that knocked the former champion out. However, Martin suffered a detached retina during the fight, and announced his retirement from boxing after the fight.
Martin's death received little coverage in the boxing media.
