Not before 5pm
Ajla TOMLJANOVIC (AUS)  v Tamara ZIDANSEK (SLO)
Dayana YASTREMSKA (UKR)  v Magda LINETTE (POL)
Tomljanovic and Zidansek have played each other twice before - both times last year, and they have one win apiece. The Australian won their only match on a hard court, though, winning 2-6, 6-1, 6-3.
Yastremska and Linette's only previous encounter was an extremely intriguing and tight affair - in the semifinals of the 2018 Connecticut Open. Both sets went to tiebreaks, with the Ukrainian winning both of them - 7-6(3), 7-6(4).
