(Born 1956) Born in Prague, she defected to the United States in 1975 because the Czech Tennis Federation had taken most of her earnings. A bit heavy early in her career, Navratilova won the first two of her nine Wimbledons in 1978-79 but subsequent losses led her to pursue a grueling fitness regimen. This paid off: She won 18 singles Grand Slams (58 overall), 167 total singles titles, and even more doubles crowns, many with partner Pam Shriver. A Wimbledon finalist at 37, Navratilova retired from singles in 1994, but returned to play doubles in 2000. In 2003 she tied Billie Jean King with 20 overall Wimbledons, taking the mixed doubles at age 46.
