Stadium (11 a.m. start)
 Garbiñe Muguruza (ESP) vs.  Sloane Stephens (USA) – Either is capable of winning this match, but Muguruza has a slightly better chance of advancing.
 Venus Williams (USA) vs.  Johanna Konta (GBR) – Venus had a great 2017, but this could be the type of win to propel her toward similar results in 2018.
 Jelena Ostapenko (LAT) vs.  Petra Kvitova (CZE) – Mild upset?
 Agnieszka Radwanska (POL) vs. [WC] Victoria Azarenka (BLR) – If Vika is playing well, she tends to beat a player like Radwanska.
 Karolina Pliskova (CZE) vs. Zarina Diyas (KAZ) – The former #1 needs to show she is still in the mix. She is.
 Angelique Kerber (GER) vs. [Q] Yafan Wang (CHN) – See above
