DeWit's first fight came at the Alberta provincial championships in March 1979 in Medicine Hat. Snatic entered deWit in the light heavyweight intermediate novice division for boxers age 17 to 20 with less than 10 fights. DeWit knocked out his first opponent in 20 seconds which caused the coaches of the six other fighters in the division to pull their fighters. DeWit had won his first championship. Snatic then entered deWit in the
British Columbia Golden Gloves championships where he fought 18-year-old Shane Anderson who was the western Canadian 178-pound champion and a veteran of about 40 fights. DeWit lost by decision, but he did beat Anderson in two of three return matches. In the last of those bouts, deWit knocked out Anderson, who never fought again. Snatic then took deWit to fight at the
Washington State Penitentiary where he knocked out his opponent in the opening minute of the first round. Afterwards in April 1982, Snatic decided to sell his ranch and moved to Calgary. deWit went with him in order to find sparring partners, and to train with a Ugandan exile named Mansoor Esmail, who was Calgary's top boxing coach, and was considered a physical conditioning genius. DeWit's first major victory came in Las Vegas in June 1982 when he knocked out Cuba's Pedro Cardenas to win his first North American title. Then he won gold at the Commonwealth Games, taking him a total of three minutes and 12 seconds to knock out three opponents. In March 1983 he defeated
Alexander Yagubkin of the U.S.S.R. to win the world title. Then, in September 1983 he defended his North American title against highly touted Cuban Aurelio Toyo. Leading up to the 1984 Olympics, a benefit in Calgary featuring boxing fan
Ryan O'Neal and
Farrah Fawcett raised $70,000 to finance DeWit's training. At this point Snatic began importing professional sparring partners from the United States.
1984 Olympics At the
1984 Los Angeles Olympics deWit lost the gold medal match in the heavyweight division to
Henry Tillman of the United States. Heading into the Olympic Games, deWit and fellow Canadian Shawn O'Sullivan were considered favorites, particularly by Canadian fans and the Canadian media. The Tillman-deWit gold medal final featured no decisive blows; however, deWit appeared to win the first two rounds against Tillman with productive work to Tillman's midsection, although Tillman clearly won the third round. Nevertheless, Tillman won by a 5-0 decision. Three of the five judges controversially scored every round for Tillman. The unanimous decision startled
Howard Cosell who was calling the bout for ABC Sports. "Good Lord! How do you like that?" Cosell blurted when the decision was announced. During his post-fight interviews, Cosell informed both Tillman and deWit that he personally disagreed with the official verdict. Tillman had also won a controversial decision in his semifinal bout, as had deWit.
