[Williams S.] (8) vs. Sharapova M. -- Wattage. Bright lights. Maria Sharapova will be fresh and this is her best chance to beat Serena Williams. Serena needs to be focused and not expect to use this match to shake off rust.

[Sabalenka A.] (9) vs. Azarenka V. -- Tough matchup for both, slight nod to Sabalenka.

Allertova D. (Q) vs. [Kvitova P.] (6)

Zheng S. vs. [Williams V.] -- Venus cannot have a letdown or get into a three-set match.

Niculescu M. vs. [Yastremska D.] (32)

[Zhu L.] vs. Wang X. (Q)
Doi M. vs. [Keys M.] (10)
[Konta J.] (16) vs. Kasatkina D. -- Tough matchup for both. Slight advantage to Konta because of her serve while Kasatkina plays better on hardcourt.
[Gasparyan M.] vs. Hon P. (Q)
Alexandrova E. vs. [Stosur S.] (WC)

[Kuzmova V.] vs. Van Uytvanck A.
Dolehide C. (Q) vs. [Wang Q.] (18)
[Sakkari M.] (30) vs. Giorgi C. -- A true toss-up. Giorgi has been playing well and Sakkari always brings it. Most recent match went to Sakkari a few weeks ago.

[Davis L.] vs. Larsson J. (Q)
Diyas Z. vs. [Barty A.] (2) -- Unfortunate matchup for Diyas who has hit her stride in recent weeks.
