Kirsten Flipkens and Elena Rybakina will meet for the first time. Flipkens, a former Top 15 player and Wimbledon semifinalist, reached the Libéma Open final last year, losing to Aleksandra Krunic. She avenged that loss to Krunic in the first round this week. Flipkens also reached the 's-Hertogenbosch final in 2013, losing to Simona Halep, and the semifinals two other times.
Greet Minnen and Veronika Kudermetova are also facing off for the first time. Rapidly rising Russian Kudermetova is into her fourth quarterfinal in her last five WTA events, having reached that stage at Lugano, Istanbul, and Nurnberg, before a third-round showing at Roland Garros last week.
Top seed Kiki Bertens and Arantxa Rus will complete their all-Dutch second-round affair which was interrupted by rain on Thursday. Bertens leads 7-5 4-3 and holds two break points for a 5-3 lead, after being down 1-5 and two set points in the opening set.
Natalia Vikhlyantseva and Paula Badosa Gibert's second-round meeting did not start on Thursday and was postponed to Friday. Vikhlyantseva reached her only WTA singles final to date at this event in 2017, falling to Anett Kontaveit in straight sets in the championship match.
