Viktoria Kuzmova made her WTA grass-court debut here last year - and reached her second career semifinal, upsetting Alison Van Uytvanck en route.
Local wildcards Bibiane Schoofs and Arantxa Rus clash in the first round. Schoofs won their only previous meeting 6-4, 6-4 in the first round of an ITF W15 event in Glasgow in 2017.
Greet Minnen is playing in the first grass-court tournament of her pro career. The Belgian came through qualifying by defeating former Wimbledon finalist Sabine Lisicki 6-7(5), 6-1, 6-4 and No.1 seed Fiona Ferro 6-4, 6-3.
Veronika Kudermetova came through qualifying to reach her maiden quarterfinal here last year. It was the Russian's second WTA main draw of her career - and for the second time, she upset a Top 30 player in the first round. Kudermetova had shocked Carla Suárez Navarro in Stuttgart on her WTA debut, and in 's-Hertogenbosch she ousted defending champion Anett Kontaveit in the first round. This year, she enters the tournament fresh off yet another upset, having stunned Caroline Wozniacki in the first round of Roland Garros.
