Karolina Muchova is seeking to equal her best hard court event of the year. The Czech is trying to reach her second quarterfinal, having reached that stage in Dubai, where she was ultimately beaten by Elina Svitolina.
Wildcard Kristie Ahn reached the last eight in San Jose at the start of August. She beat Ajla Tomljanovic and Elise Mertens before eventually falling to Donna Vekic in her first WTA Tour quarterfinal since Nottingham 2017.
Aliaksandra Sasnovich holds a 5-0 career head-to-head record against Magda Linette. The Belarusian won three ITF matches between the pair before taking a qualifying win in Miami 2017. The last time they met was Indian Wells in 2018, with Sasnovich coming through 5-7, 7-6(2), 7-6(4).
Linette has won eight straight sets in the Bronx, having come through qualifying unblemished before defeating Kaia Kanepi, 6-2, 7-5.
Fiona Ferro won her last match against No.1 seed Wang Qiang, coming out on top in Strasbourg on the clay earlier this year.
Wang has victories in both the pair’s previous hard court encounters, winning in straight sets in Guangzhou last year before taking a 6-4, 6-3 victory in the Australian Open first round earlier this year.
The Chinese has a fine record on the surface in 2019, having reached the quarterfinals in Miami and the last 16 of Indian Wells, both Premier Mandatory events.
Ferro is seeking to make the quarterfinals in a fourth successive WTA event, having done so in Bastad, Lausanne and Palermo – all tournaments played on clay.
Mihaela Buzarnesu beat Anna Blinkova in their only previous meeting, an ITF match in Poitiers in 2017.
She last won back-to-back Tour matches in Rome, where Jelena Ostapenko and Julia Goerges retired from successive matches.
