Agnieszka Radwanska has become the fourth player to qualify for the WTA Championships, which will be held in Istanbul, Turkey, from October 23-28. The 23-year-old was won three titles this year (Dubai, Miami, and Brussels) and became the first Polish woman since 1939 to reach the final of a Grand Slam, at Wimbledon.
Radwanska joins Victoria Azarenka, Maria Sharapova, and Serena Williams as qualifiers. Petra Kvitova, Angelique Kerber, Sara Errani, and Li Na are currently occupying the final four qualifying spots, with Samantha Stosur, Marion Bartoli, and Caroline Wozniacki trailing them.
