Margaret Court AO, MBE, also known as Margaret Smith Court, is a retired world No. 1 professional tennis player. She is currently a Christian minister in Perth, Australia but is best known for her sporting career, in which she amassed more major titles than any other player in history. In 1970, Court became the first woman during the open era to win the singles Grand Slam. Court won a record 24 of those titles, a record that still stands. She also won 19 women's doubles and 21 mixed doubles titles, giving her a record 64 major titles overall. She is the only woman to win the mixed doubles Grand Slam, which she accomplished twice. Her all surfaces singles career winning percentage of 91.68% is one of the best of all-time, according to the Sporteology website. Her open era singles career winning percentage of 91.37% is also unequaled. Her win-loss performance in all Grand Slam singles tournaments was 90.12%. She was 95.31% at the Australian Open, 90.38% at the French Open, 85.10% at Wimbledon, and 89.47% at the US Open.
