Another week, another continent: defending champion Zarina Diyas and Kateryna Kozlova squared off just last week in the first round of Chicago, and will face each other again today. Diyas won that match 3-6, 6-2, 6-1, and leads the head-to-head 2-1 overall.
2015 finalist Magda Linette also faces a familiar foe in fast-rising Slovenian Tamara Zidansek. The pair have already met twice this year, in the first round of Rabat and the final of the Bol 125K, and Zidansek has won both times - without dropping more than four games in any set.
No.1 seed Zhang Shuai faces Nao Hibino for the first time since the Tokyo ITF $100,000 final in 2015, won by the Chinese player 6-4, 6-1. Four-time WTA finalist Hibino is bidding to make her first quarterfinal at this level since Nanchang last August and to notch up a sixth career Top 50 win - and second of 2018, after the Japanese player defeated Samantha Stosur in Taipei City.
No.2 seed Hsieh Su-Wei takes on returning mother Mandy Minella for the second time in her career today. The Chinese Taipei No.1 won their only previous meeting 6-4, 4-6, 6-2 in the second round of Kaohsiung in 2016. A victory for Gstaad runner-up Minella would be the first Top 50 win of her comeback from maternity leave, and first since beating Caroline Garcia in Taipei City last February.
