Nadia Petrova

Petrova was born in Moscow. Her parents were both very athletic: her father Viktor was a leading hammer thrower, while her mother Nadezhda Ilyina won a bronze medal at the 1976 Montreal Olympics in the 400 meter relay. Her father is still an athletics coach, and her mother was an athletics coach until her death in 2013. As a child, Nadia did a lot of travelling around the world with her parents. She eventually settled in Egypt, where she trained with Mohammed Saif and her parents.

Petrova is an all-court aggressive player who is capable of hitting winners off both wings, but particularly off her back-hand and which she hits flat and with slice. Petrova's serve is considered her biggest asset and one of the best serves in the women's game. In 2010, she hit the most aces on the tour with 306. She had an impressive 70% of first serve points won and also won over 74% of her service games. As an accomplished doubles player, Petrova's volleying skills are considered exceptional and she is not afraid to come into the net to finish off points. Petrova's main weakness is her movement around the court as she is often slow to retrieve balls and can sometimes struggle to defend well during rallies. Also, her forehand is sometimes erratic and can produce many unforced errors. Petrova states hard courts as her preferred surface, however, she has been most successful on clay courts where she can dictate play easier because it gives her more time on the ball. She is known for her unpredictability and inconsistency.

As a junior, Petrova won the 1998 French Open, beating Jelena Dokić in the final.[1] The same year, she finished runner-up at the Orange Bowl to Elena Dementieva and she also finished runner-up at the junior 1999 US Open to Lina Krasnoroutskaya.
