Beijing:Women's top seed Ana Ivanovic of Serbia pulled out of the Olympic Games tennis tournament on Sunday in a fresh blow after the first day of competition was heavily disrupted by prolonged thunderstorms.
The French Open champion, who will cede her world number one status to compatriot Jelena Jankovic tomorrow, has failed to recover from an injured right thumb and joins Maria Sharapova, Tatiana Golovin and Amelie Mauresmo on the sidelines.
Atlanta Games 1996 champion Lindsay Davenport has also decided not to play in the singles.
"This is the worst moment of my career," said the 20-year-old Serb, who has been undergoing osteopathic treatment here in a bid to alleviate the pain and restore the strength in the thumb she injured in last month's WTA Rogers Cup in Montreal.
"In the past month I have been in so much pain and I haven't been able to practise for 10 days.
"I haven't even hit a ball since arriving in Beijing," said Ivanovic, who was slated to play a first round match against Mariya Koryttseva on Monday.
The news came after a rain-disrupted first day of competition during which only nine of the 45 scheduled matches were completed.
