Johanna Konta has been drawn to face Agnieszka Radwanska, Garbine Muguruza and Karolina Pliskova should she earn a place at the end-of-season WTA Finals.
The British number one currently holds possession of the eighth and final spot for the tournament in Singapore but she will be demoted to an alternate should Svetlana Kuznetsova win the Kremlin Cup in Moscow.
The two-time Grand Slam champion is through to the semi-finals in Russia but for now at least, Konta will begin to anticipate potential clashes next week.
Those four players have been drawn in the White Group with Angelique Kerber heading the Red Group just weeks after claiming the world number one position from Serena Williams.
The German – who has won the Australian Open and US Open in 2016 – will face Simona Halep, Madison Keys and Dominika Cibulkova.
