Serena Williams has overcome injuries and illness to win her fifth Wimbledon title.
A respiratory infection may make it more difficult for Agnieszka Radwanska's to defeat Serena Williams at Wimbledon and become No. 1 in the world.
Agnieszka Radwanska has been here before ... sort of. In 2005, she won the Wimbledon title as a junior. Saturday she'll attempt to become just the fifth juniors champ to win the women's crown.
All eyes will be on the Serena Williams-Victoria Azarenka tilt Thursday. But there are two other semifinalists who might just put on a better show.
