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.
The Wimbledon champ has two younger brothers who play tennis, and one of them, Marko, is a frequent practice partner.
Li Na defeated Francesca Schiavone 6-4, 7-6 (0) in the French Open final to become the first Chinese player to win a Grand Slam.
