Fourth seed Zheng Saisai has never played Natalija Kostic before.
Zheng is one of five Top 50 players in the main draw here - along with Magda Linette, Petra Martic, Elina Svitolina, and Wang Qiang.
Nao Hibino and Arina Rodionova have met on five previous occasions - all on hard courts. The Australian has the edge - having beaten the top seeded Japanese in the Round of 16 in Tianjin last year, as well as the Launceston quarterfinal and the Burnie Round of 32. She also picked up a win in the 2017 Auckland quarterfinal. Hibino's only win of their rivalry came in the Round of 16 in Vancouver last year.
You Xiaodi and Ellen Perez played each other for the first time last year in qualifying for Zhengzhou. The Chinese player won 7-6(5), 6-2.
