Maria Sharapova is back up to No. 2 after winning her fourth title of the season at the China Open. Sharapova defeated Petra Kvitova 6-4, 2-6, 6-3 in Sunday's final for her fifth straight win over the Czech, who falls to No. 4 behind Simona Halep. In addition to getting herself back up to No. 2 after being as low as No. 9 this season, Sharapova also clinched the No. 2 seed for the WTA Finals, which ensures she won't be placed in No. 1 Serena Williams' group. The earliest the two could meet at that tournament would be the semifinals.
This week marks the 209th week at No. 1 for Serena, tying her for No. 4 on the all-time list with Martina Hingis. She'll take sole ownership of No. 4 next week, sitting behind three familiar legends: Steffi Graf, Martina Navratilova and Chris Evert.
Eugenie Bouchard lost in her first match at the China Open but rises to a new career-high ranking of No. 6. Can she finish the season in the top five? Bouchard has already qualified for her first WTA Finals but she's still playing the Generali Ladies Linz this week and entered in Luxembourg next week. In fact, based on the results at the China Open, the entire eight-player field for the WTA Finals is finally set, though the No. 3 through eight seeds could change over the next two weeks:
1. Serena Williams
2. Maria Sharapova
3. Petra Kvitova
4. Simona Halep
5. Eugenie Bouchard
6. Agnieszka Radwanska
7. Ana Ivanovic
8. Caroline Wozniacki
The doubles field for the WTA Finals are also coming together, with seven of eight teams confirmed:
1. Roberta Vinci/Sara Errani
2. Peng Shuai/Hsieh Su-Wei
3. Cara Black/Sania Mirza
4. Elena Vesnina/Ekaterina Makarova
5. Raquel Kops-Jones/Abigail Spears
6. Kveta Peschke/Katarina Srebotnik
7. Carla Suarez Navarro/Garbine Muguruza
The teams of Anastasia Rodionova/Alla Kudryavtseva and Martina Hingis/Flavia Pennetta are trying to chase down the final spot. Both teams are at the Tianjin Open this week.
