Martina Navratilova is a retired Czech American tennis player and coach, and a former World No. 1. Billie Jean King said about Navratilova in 2006, “She’s the greatest singles, doubles and mixed doubles player who’s ever lived.” Navratilova won 18 Grand Slam singles titles, 31 major women’s doubles titles (an all-time record), and 10 major mixed doubles titles. She reached the Wimbledon singles final 12 times, including nine consecutive years from 1982 through 1990, and won the women’s singles title at Wimbledon a record nine times. She and King each won 20 Wimbledon titles, an all-time record. Navratilova is one of just three women to have accomplished a career Grand Slam in singles, women’s doubles, and mixed doubles (called the Grand Slam “boxed set”) a record she shares with Margaret Court and Doris Hart. She holds the open era record for most singles titles (167) and doubles titles (177). She recorded the longest winning streak in the open era (74 consecutive matches) and three of the six longest winning streaks in the women’s open era.
