Martina Navratilova (born October 18, 1956, in Prague, Czechoslovakia) is a former World No. 1 woman tennis player. Billie Jean King said about Navratilova in 2006, "She's the greatest singles, doubles and mixed doubles player who's ever lived." Tennis writer Steve Flink, in his book The Greatest Tennis Matches of the Twentieth Century, named her as the second best female player of the 20th century, directly behind Steffi Graf. Tennis magazine has selected her as the greatest female tennis player for the years 1965 through 2005. She won 18 Grand Slam singles titles, 31 Grand Slam womens doubles titles (an all-time record), and 10 Grand Slam mixed doubles titles. She won the women's singles title at Wimbledon a record 9 times. She is one of just three women to have accomplished a career Grand Slam in singles, women's doubles, and mixed doubles. She holds the open era record for most singles and doubles tournament wins (167 and 177 titles respectively)..
