Four players remain in contention for the final three qualifying spots for the BNP Paribas WTA Finals Singapore presented by SC Global – Sloane Stephens, Elina Svitolina, Karolina Pliskova, and Kiki Bertens - and two of them, Stephens and Pliskova, could qualify as early as Sunday. 

Five players have already qualified for the WTA Finals, which will be hosted in Singapore for the fifth and final year before relocating to Shenzhen in 2019. World No.1 Simona Halep, Wimbledon champion Angelique Kerber, US Open and Indian Wells champion Naomi Osaka, Madrid champion Petra Kvitova, and Australian Open and Beijing champion Caroline Wozniacki.

With three spots remaining, here was the point spread on the Porsche Race to Singapore Leaderboard as of Monday, October 8th:

6. Sloane Stephens: 3,943 points (accepted a wildcard into Moscow)
7. Elina Svitolina: 3,850 points (as of now, not entered in Moscow or Luxembourg)
8. Karolina Pliskova: 3,720 points (Moscow)
9. Kiki Bertens: 3,710 points (Moscow)

The scenarios heading into Sunday, which will turn on the result of the Tianjin Open final and the release of the draws in both Moscow and Luxembourg, are listed below. The Moscow draw is scheduled for 1pm local time. The Luxembourg draw is on Saturday, at 6pm local time. 

SCENARIO 1: Sloane Stephens qualifies.

Stephens can qualify upon conclusion of the Moscow draw on Sunday if Svitolina does not play next week. In other words, so long as Svitolina is not in either the Moscow or Luxembourg draw, Stephens will clinch her qualifying spot and make her Singapore debut.

SCENARIO 2: Karolina Pliskova qualifies. 

Pliskova can qualify on Sunday upon conclusion of the Moscow draw, by winning the Tianjin title so long as Svitolina does not play next week. Pliskova plays Caroline Garcia in Sunday's final, in a battle of two 2017 WTA Finals semifinalists. The Tianjin title would move Pliskova to No.7 on the Race Leaderboard, ahead of Svitolina. 

The Tianjin final is on Sunday, not before 2pm local time.

SCENARIO 3: Both Stephens and Pliskova qualify. 

If both Stephens and Pliskova earn qualification on Sunday (subject to the above scenarios), then the final Singapore spot will go to either Svitolina or Bertens. In this scenario, the Dutchwoman will be tasked with chasing down Svitolina and overtaking her for the eighth and final spot. 

Bertens, who will have a first-round bye, would need to win two matches to reach the semifinals in order to pass Svitolina for the final qualification spot. Again, this assumes that Svitolina will not be able to play either Luxembourg or Moscow. 

Should neither Stephens and/or Pliskova qualify on Sunday, all remaining spots will be decided in the final week of the season. 

Qualification for the WTA Finals is based on a number of variables and only becomes official when the respective player or team has reached a point total that will assure a Top 8 finish on the Porsche Race to Singapore Leaderboard. It is only at that point when we will officially acknowledge a player’s qualification to the BNP Paribas WTA Finals Singapore presented by SC Global.
