Kateryna Kozlova will play in her first quarterfinal since Budapest in February. She lost in Hungary over three sets to Alison Van Uytvanck.
She has never faced WTA World No.134 Nina Stojanovic before.
Peng Shuai’s victory over Kristyna Pliskova was her first over a Top 100 player in the 2019 season.
She has a 1-0 career head-to-head record against Zhu Lin, having beaten her in the quarterfinals of this very tournament in 2017.
Rebecca Peterson has a 1-0 record against Magda Linette, having beaten the Pole earlier this year over three sets in Strasbourg. However, that was on clay.
Linette has won eight of her last nine singles matches, having lifted the title in the Bronx before a second-round exit at the US Open versus Naomi Osaka.
Elena Rybakina and Viktorija Golubic will play for the first time.
Rybakina is aiming to reach her third WTA Tour semifinal of the year, having done so previously on the grass of ‘s-Hertogenbosch and the clay of Bucharest. Golubic is playing just her second quarterfinal, having lost in Hua Hin.
