World #1 Serena Williams has defeated Angelique Kerber, Agnieska Radwanska and Petra Kvitova in straight sets at the TEB BNP Paribas WTA Championships in Istanbul, Turkey. This was her 76th win of the year (to only four losses). In the other half of the draw Li Na and Jelena Jankovic qualified for the semifinals, with the Chinese player going undefeated 3-0 against Victoria Azarenka, Sara Errani and Jankovic. Li eliminated World #2 from the field with a 6-2 6-1 win against the curiously unmotivated Belarussian.
The last final semifinal slot is being fought over between the two remaining lefties: Kvitova and Kerber. Serena will face Jankovic in the semifinals, a replay of the China Open final won by the World #1 a few weeks ago. Interestingly, the match-up between the lefty K's is a reprise of the finalof the Tokyo Open final where Kvitova emerged victorious despite dropping a bagel middle set. Li Na will face either Kvitova or Kerber and will simply need to win that match to reach the Year-End Championships final to reach World #3 in the world for the first time.
