The draw for the lucrative season-ending WTA finals was made in Singapore on Friday.
Newly crowned world number one Angelique Kerber has been drawn in the red group alongside tournament debutant Madison Keys from the US, Slovak Dominika Cibulkova and Romanian Simona Halep.
At the ceremony Kerber reflected on her breakthrough season which saw her win the Australian and US Opens and take over the world number one ranking from Serena Williams, who withdrew from the event due to a shoulder injury.
She said: “You know, it was an amazing year for me, and everything that has happened, it’s still crazy, I really try to enjoy every single moment, it’s something I’ve always dreamed of so it’s really nice to be back here in Singapore and I’m looking forward (to the matches).”
The white group consists of defending champion Agnieszka Radwanska from Poland, Czech Karolina Pliskova and Spaniard Garbine Muguruza.
The eighth and final spot (fourth in the white group) will be taken by either Britain’s Johanna Konta or Russian Svetlana Kuznetsova.
Kusnetsova will qualify for the seaosn-ending championships if she beats Australian world number 49 Daria Gavrilova in the Kremlin Cup final on Saturday.
