Serena Williams, playing another close match today in Doha, is now 2-0 at the Sony Ericsson Championships. Williams, a member of the maroon group, defeated her sister, Venus, 5-7, 6-4, 7-6. Yesterday, she defeated Svetlana Kuznetsova 7-6, 7-5.
Williams' victory, combined with the retirement of Dinara Safina, makes her number 1 in the world again.
In the white group, Jelena Jankovic retired when Safina retired with a lower back injury at 1-1. And Caroline Wozniacki came from behind to defeate Victoria Azarenka, 1-6, 6-4, 7-5. The fifth game of the second set lasted 20 minutes, and had a bit of everything in it. Wozniacki and Azarenka, both good players, present a study in emotional contrast. Wozniacki appears to let most adversity slide, whereas Azarenka tends to become increasingly intense as a match goes on. Wozniacki, considered by many to be too depleted to compete at her best right now, hit 32 winners.
Tomorrow, the only white group match will feature Wozniacki against Vera Zvonareva, the alternate who is replacing Dinara Safina. Zvonareva was last year's finalist.
In the maroon group, Serena Williams will play Elena Dementieva, and Svetlana Kuznetsova will play Venus Williams.
