Ken McGregor joined countryman Frank Sedgman to win the first and only Grand Slam in men's doubles in 1951, and the team won three of the "Big Four" the following year. An ex-Australian rules football player, this talented Aussi brought a competitive attitude to the game of tennis. 6-foot-3 and 180-pounds he was a Top 10 singles player in 1950-52 reaching as high as World No. 3 in 1952. McGregor was also a finalist at the 1950 and 51 Australian Championships and at Wimbledon in 1951. In his third straight Australian final in 1952, this furious serve and volleyer defeated his friend and doubles partner to claim the championship. A surprise selection to play singles in the 1950 Davis Cup tie against the Americans, McGregor won the opening match, leading the Australians to victory and ending the Americans' four-year possession of the Cup.
