Roy Stanley Emerson (born 3 November 1936) is an Australian former number one tennis player who won 12 Major singles titles and 16 Grand Slam tournament men's doubles titles. He is the only male player to have completed a Career Grand Slam (winning titles at all four Grand Slam events) in both singles and doubles. His 28 Major titles are an all-time record for a male amateur player. Roy Emerson is the first male player to win each amateur Major title at least twice in his career. He is one of only seven men to win all four Majors in his career. He was the first male player to win 12 Majors. He is the only male player to win 6 Australian Championships and five of them consecutive (1963-67). His 12 wins have since been surpassed. Emerson is only one of five tennis players all-time to win multiple slam sets in two disciplines, only matched by Margaret Court, Martina Navratilova, Frank Sedgman and Serena Williams.
