In August 1975, Watson, together with George Harvey, represented Rhodesia at El Rincon Golf Club in Bogotá, Colombia, among 18 two-man nation teams, competing for the Coupa El Rincon over 72 holes stroke-play. The Rhodesian team won, ten strokes ahead of Sweden, and Watson won individually on a score of 7-under par 281, five strokes ahead of Jan Rube, Sweden.[2]
In the early 1970s, Watson served in the Rhodesian military during what he described as a "terrorist war." Watson was awarded Rhodesian Sportsman of the Year in 1975.[3] He would then immigrate to neighboring South Africa to pursue his golf career.[4][5] He represented South Africa at the World Series of Golf in 1980 and 1982.[6]
Watson finished tied for second in the 1985 U.S. Open, missing out on forcing a playoff by one shot, having incurred a two-stroke penalty earlier in the tournament. The penalty was assessed on the eighth hole in the first round, after he had waited longer than the allowed ten seconds for a putt that had hung on the lip of the hole to drop in. The ball did fall into the hole, but the birdie was disallowed and the penalty strokes added. The USGA and The R&A, the sports governing bodies, have since amended the penalty for this rules infraction to just a single stroke. Andy North eventually beat him by one shot.[8]
Watson's career came to a sudden halt when he was injured while playing in the 1985 Goodyear Classic in South Africa. While hitting his ball out of the rough with a 9-iron, he struck a tree stump that had been hidden from view causing damage to his wrist, elbow and neck. He went on to win the tournament, but his problems had just begun.[9] He required surgery on his wrist and neck, and was initially told that he would never play again.[4] He did, but was unable to consistently reach the high standard that he had previously attained and after several more operations he retired towards the end of the 1990s.[10][11][12]
