Another note about Navratilova: She defected immediately after losing the 1975 US Open semifinal. She told only one fellow player of her intention to do so as the communist Czech chaperones with her on the trip to the States were monitoring her every move. That person was her opponent and close friend who defeated her and kept her secret, Chris Evert. Martina was just 18 and Chris was 20. Imagine the stress and tension on two such young athletes competing for one of the biggest titles in the sport.
There were immediate and harsh penalties Martina had to suffer. She could not visit her parents and sister for four years and they could not travel to watch her play. Phone calls home were wiretapped by the Czech government. Martina did not tell her mother of her intent to defect on her father's instruction. He felt it would further guarantee both their safety. That had to be agonizing for both. Her televised matches at the biggest events like Wimbledon were banned from broadcast. Her citizenship was stripped and for a time she became a pariah at home, unable to reenter the country. Also her Fed Cup coach, Vera Sukova, a former top player herself shouldered the brunt of the blame for the country losing its top woman player. Her coaching career was severely hampered as result. Still things worked out for most in the end. Martina became a US citizen and an all time great. She was eventually reunited with her family, welcomed warmly back to the country in 1986 when it hosted the Fed Cup, and had her Czech citizenship restored alongside her American one in recent years. Sukova's daughter (Helena) and son (Cyril) went on to become top singles amd doubles players in the 80s and 90s. Helena was for a time the best doubles player in the world, following in Martina's footsteps, and reach four Grand Slam finals in singles where she had the misfortune to run up against the three greatest women players of the last 45 years (Evert, Martina and Steff Graf). In another time, she could have won some of those finals.
