Rodney George Laver AC MBE is an Australian former tennis player. Laver was ranked world No. 1 in nine different years, which is an all-time record in tennis. He was the No. 1 ranked professional from 1964 to 1970, spanning four years before and three years after the start of the Open Era in 1968. He also was the No. 1 ranked amateur in 1961–62.
Laver's 198 singles titles are the most in tennis history. This included his all-time men's record of 10 or more titles per year for seven consecutive years. He excelled on all of the court surfaces of his time: grass, clay, hard, carpet, and wood.
Laver won 11 Grand Slam singles titles, though he was banned from playing those tournaments for the five years prior to the Open Era. Laver is the only player, male or female, to win all four Grand Slam singles titles in the same calendar year twice, in 1962 and 1969, the latter remains the only time a man has done so in the Open Era. He is second of three male players to win each major title twice.
