Maria Sakkari has a 1-0 career head-to-head record against Aryna Sabalenka. The Greek won their only previous meeting in Cincinnati earlier this year.

Sabalenka lost her first four matches against Top 25 players in 2019, including a Fed Cup defeat to Ashleigh Barty, but has since gone 5-2 against the same category of rival.

The Belarusian has already enjoyed success in Asian this year, taking the titles in Wuhan and Shenzhen.

No.1 seed Kiki Bertens and Donna Vekic are familiar foes. This will be their seventh meeting, with the series split 3-3, though the Dutchwon has a 3-2 edge on the WTA Tour, including three wins in their last four meetings.

Bertens recently came out on top in Beijing, winning a tense battle, 3-6, 6-1, 7-6(3).

Vekic has lost her last six matches against Top 10 players, though three of the last five have needed three sets, including two third-set tiebreaks that went against her.

Madison Keys’ only previous meeting with Saisai Zheng was in Zhuhai in 2015. The American won, 6-3, 6-2.

Keys, whose trip to Zhuhai last year ended with a knee injury, holds a 10-7 record against Top 40 players in 2019. Five of these defeats have been against the Top 15, however.

Zheng is aiming to become the second wildcard to qualify through the group stage. Zhang Shuai is the only player in this position to have achieved this feat – or even won a match.

Zheng did come close to upsetting Venus Williams in 2015, her only previous appearance in Zhuhai. She won the opening set but ultimately lost, 4-6, 6-1, 6-1 to the eventual champion.
