Maria Sharapova, who sprained her ankle in Tokoyo, withdrew from the WTA Championships today, citing continued swelling of her ankle as the reason. Sharapova, who was in the White Group, lost to Li Na today. Li's 7-6, 6-4 victory included her winning seven straight points when she was down 0-4 in the first set tiebreak. The Russian star had already lost her first match to Samantha Stosur.
Stosur lost today to Victoria Azarenka, which gives Azarenka a 5-0 record against Stosur. In the Red Group, Vera Zvonareva defeated Caroline Wozniacki 6-2, 4-6, 6-3. Zvonareva hit 49 winners and made 49 unforced errors.
Here are the results so far:
Caroline Wozniacki, 1-1
Petra Kvitova, 1-0
Vera Zvonareva, 1-1
Agnieszka Radwanska, 0-1
Maria Sharapova, 0-2, withdrawn
Victoria Azarenka, 1-0
Li Na, 1-0
Sam Stosur, 1-1
After the round-robin has been completed (see rules here), the best-performing player from the Red Group plays the second best-performing player from the White Group, and vice versa. The winners of those two matches then meet in the final.
Tomorrow, Azarenka plays Li, Wozniacki plays Kvitova and Zvonareva plays Radwanska. (Azarenka will play her third round-robin match against first alternate Marino Bartoli.)
