None of the quarterfinalists have previously faced each other in WTA Tour action.
Garbiñe Muguruza is chasing her first Tour semifinal since winning in Monterrey last April.
Of the nine Chinese players who played the first round, Wang Qiang is the only one left standing.
Ekaterina Alexandrova has already accounted for one home player. She defeated Peng Shuai in straight sets in the second round. She has a 2-1 winning record on Tour against Chinese players.
Elise Mertens’ last quarterfinal appearance on the WTA Tour came in Osaka in September 2019. Subsequently, she made three successive second-round exits before breaking that duck in Shenzhen.
No.3 seed Mertens is the highest-ranked player left in the event following earlier exits for top seed Belinda Bencic and defending champion Sabalenka.
Kateryna Bondarenko’s match with Kristyna Pliskova is the only encounter between two non-seeded players. It is also the only match between two players yet to drop a set in the tournament.
Pliskova scored an impressive victory over Sabalenka, the No.2 seed, in the previous round.
