   The most successful player at the year-end WTA Championships is none other than the legendary Martina Navratilova. If winning 18 singles Grand Slam titles, 31 Grand Slam doubles titles and 10 Grand Slam mixed doubles titles was not enough, Navratilova bagged 8 year-end championships, most by any player. She also holds the record for maximum number of finals at year-end Championships with 14 finals, double the number of finals reached by Serena Williams.

On the other hand, we will have three debutants this year as Cibulkova, Keys and Kuznetsova will be making their first appearance in Singapore.
