Anna Kournikova is probably one of the most famous former female tennis players in the world….and she never won a singles event at any Grand Slam. The stunning 27 year old Russian turned pro at the tender age of 14 and in 2000 peaked at #8 ranked in the world for singles. Her true success on the court came in doubles play with partner Martina Hingis where she took home the Australian Open title in 1999 and 2002. Due to a series of back and spinal injuries she was forced from the court, but has remained active taking part in the Miami Triathlon in some sexy black spandex. Her modeling career is still active and she remains one of the hottest women around.
