MATCH POINTS
Svitolina is unbeaten in Singapore, defeating Petra Kvitova, Karolina Pliskova, and Caroline Wozniacki in the round-robin stage, then Kiki Bertens in the semifinal.
This is the biggest final of Svitolina's career. Her best-ever Grand Slam result has been reaching the quarterfinals of Roland Garros in 2015 and 2017, and the Australian Open in 2018.
LOOK: Elina Svitolina's road to the final
Svitolina was the first Ukrainian to qualify for the WTA Finals in singles when she made her debut appearance in Singapore in 2017.
Last year, she went 1-2 in the round-robin stage, failing to progress despite beating World No.1 Simona Halep in straight sets.
Sloane Stephens is also unbeaten in Singapore, having got past Karolina Pliskova, Angelique Kerber, Kiki Bertens, and Naomi Osaka to reach the final.
This is Stephens's debut at the WTA Finals, although she was the second alternate in 2013 - but did not play.
The last debutante to win the event was Dominika Cibulkova in 2016.
LOOK: Sloane Stephens' road to the final
Stephens leads the head-to-head 2-1. She also won their most recent clash, earlier this year in the semifinals in Montreal, picking up a 6-3, 6-3 win.
