Tennis - Former world no. 1 Caroline Wozniacki and 20 year old American Sloane Stephens will also make the trip to Istanbul - but not as part of the top 8. Instead, the two will be the alternates for the event and will get a chance to play if there are any withdrawals by any of the top 8 players.
Wozniacki is the first alternate while Stephens is the second alternate. Wozniacki has been among the top 8 players in this event thrice before from 2009-2011 while this is the first time Stephens will be heading to the season-ending Championshis.
The top 8 who have qualified for the event are Serena Williams, Victoria Azarenka, Agnieszka Radwanska, Li Na, Sara Errani, Petra Kvitova, Jelena Jankovic and Angelique Kerber.
