Arthur Ashe Stadium (Noon start)

[8] Petra Martic (CRO) vs. [23] Yulia Putintseva (KAZ) – Maybe a small upset …

[4] Naomi Osaka (JPN) vs. [14] Anett Kontaveit (EST) (late night) – Osaka seems likely to reach the final.

Louis Armstrong Stadium (11 a.m.)

[17] Angelique Kerber (GER) vs. [28] Jennifer Brady (USA) – Already underway, but I would have picked Kerber had I posted this sooner.

[6] Petra Kvitova (CZE) vs. Shelby Rogers (USA) (not before 3 p.m.) – Kvitova is in good form.
