Margaret [nee Smith] Court holds the incredible record in Mixed Doubles titles of winning 12 out of 13 consecutive Grand Slam titles. She won 7 titles in a row. Had she not lost the final of the Wimbledon Mixed doubles title in 1964, she would have achieved 3 consecutive Calendar Grand Slams in Mixed Doubles. Further, she actually won 13 out of 14 Grand Slam tournaments that she entered, having been absent from 3 consecutive tournaments in 1962 after the first of those Grand Slam titles. As history stands, she has achieved one singles Calendar Grand Slam and two mixed doubles Calendar Grand Slams - more Grand Slam achievements than any other player in history.
Of the thirty-two Grand Slam singles finals she played, she won eighteen. 3 Australian, 2 French, 9 Wimbledon and 4 USA titles. This tally left her second only to Stefi Graf in all time singles Grand Slam titles. Martina is also second in the all time ranking of doubles titles, achieving twenty of those with Pam Shriver and another eleven with other partners. In mixed doubles she won a modest ten Grand Slam trophies. In all tournaments therefore, Martina Navratilova ended her career with FIFTY-NINE Grand Slam trophies in her cabinet.
Jimmy Connors and Andre Agassi are two former, top US players who won 8 singles Grand Slam titles.However, the question does not stipulate whether the grand slams need to be only singles, or whether they are just Grand Slam titles[period]. There may be others, male or female, who won 8 Grand Slams, inclusive of singles, doubles and mixed doubles titles.
