Kenneth Bruce McGregor (2 June 1929 – 1 December 2007) was an Australian tennis player from Adelaide who won the Men's Singles title at the Australian Championships in 1952. He and his longtime doubles partner, Frank Sedgman, are generally considered one of the greatest men's doubles teams of all time and won the doubles Grand Slam in 1951. McGregor was also a member of three Australian Davis Cup winning teams in 1950–1952. In 1953, Jack Kramer induced both Sedgman and McGregor to turn professional. He was ranked as high as World No. 3 in 1952. Career In 1951 and 1952 McGregor and Frank Sedgman won seven consecutive Grand Slam doubles titles – a feat that is unmatched to this day. McGregor was also a good singles player. At the Australian Championships in 1950, McGregor beat top seed Jaroslav Drobný in an early round before losing the final against Sedgman. At the 1951 Australian Championships, McGregor beat Adrian Quist and Arthur Larsen before losing the final to Dick Savitt. Savitt also beat him in the Wimbledon final. McGregor won the 1952 Australian Championships, beating Savitt and Sedgman in the last two rounds. McGregor was a fine all-round athlete, excelling in cricket, Australian rules football, and tennis. He also played lacrosse. At , he had a powerful serve and overhead. The great tennis player Ellsworth Vines said of McGregor: "He was the same height as Pancho Gonzales, faster, moved as well and could jump higher, and once he got to the net he was difficult to pass because of his prehensile reach. The handsome Aussie had the most extraordinary overhead of all time." In his 1979 autobiography Jack Kramer, the long-time tennis promoter and great player himself who brought McGregor into professional tennis, wrote that "McGregor was one of the weakest players but one of the nicest guys who ever played for me in the pros. As nearly as I could tell, all he wanted to do was save up some money, go back Down Under and play Australian-rules football, which in fact, he played better than he did tennis. And that's what he did." In early January 1953 McGregor and Sedgman signed a contract to join Jack Kramer's professional tour. This made them ineligible to compete in the amateur Grand Slam tournaments and Davis Cup. In his 1952–1953 tour against Pancho Segura, McGregor was beaten by 71 matches to 25. In
