Six down, two to go.
The full field at the BNP Paribas WTA Finals Singapore presented by SC Global will be decided this week in Moscow, as Karolina Pliskova, Kiki Bertens and Elina Svitolina are in contention for the final two spots.
French Open finalist and Miami Open champion Sloane Stephens was confirmed as the sixth qualifier earlier on Monday, as the former US Open champion will be making her debut at the WTA Finals.
For more on how the numbers shake out, and what Bertens and Pliskova need to do this week in Moscow to head to Singapore, read more from WTA Insider below.
Both Bertens and Pliskova are in action at the VTB Kremlin Cup in Moscow this week, and the inactive Svitolina could be pushed out of the field based on their results at the Premier-level event.
