Kirsten Flipkens is bidding to make her second final in 's-Hertogenbosch, having been runner-up to Simona Halep in 2013, and fourth overall following Québec City 2012 (her sole career title to date), 's-Hertogenbosch 2013 and Monterrey 2016. The Belgian's run here five years ago included wins over Francesca Schiavone and Garbiñe Muguruza, and presaged a career-best Grand Slam showing a fortnight later as she forged her way to the Wimbledon semifinals.

CoCo Vandeweghe's only previous meeting with Aleksandra Krunic was in the first round of the 2013 US Open - the Serb's Grand Slam debut. Vandeweghe won that match 6-4, 7-6(5). Krunic is playing her third career WTA semifinal, and seeking to make her second final following Guangzhou last year.

Kirsten Flipkens and Viktoria Kuzmova, who have never played each other before, are both competing in their second semifinal of 2018. The Slovak reached her maiden semifinal as a lucky loser in Budapest in February; Flipkens has now reached the last four in two out of her last three tournaments following Nurnberg last month - each time via a victory over Kiki Bertens in the quarterfinals.

CoCo Vandeweghe's career record in 's-Hertogenbosch is 18-3. The American lost in the second round of qualifying to Arantxa Rus on her first visit in 2011 and did not play again until 2014 - when she won her maiden title as a qualifier, defeating Garbiñe Muguruza in the quarterfinals and Zheng Jie in the final. Vandeweghe lost in the 2015 quarterfinals to Kiki Bertens, regained her title in 2016 but was ousted in the first round by Carina Witthoeft last year.

World No.81 Viktoria Kuzmova is the second-highest ranked player born in 1998 following Aryna Sabalenka. Only one player ranked above the 20-year-old is younger - 19-year-old Catherine Bellis at No.66.
