Top seed CoCo Vandeweghe eased into the second round of the Libema Open while Robin Haase was given a tough workout by Ivo Karlovic in the men’s draw.

Two-time ‘s-Hertogenbosch champion Vandeweghe won the opening set against Aliaksandra Sasnovich with relative ease, but the Belarussian came back strongly in the second set before the American wrapped it up 6-2, 7-6 (7-1).

Next up is Arantxa Rus after the Dutchwoman beat Russian Ekaterina Alexandrova 6-7 (5-7), 6-4, 7-6 (9-7).

Sixth seed Alison van Uytvanck also advanced as the Belgian secured a 6-1, 6-2 victory over local wild card Richel Hogenkamp.

In the men’s side, Haase came through a gruelling 7-6 (7-3), 6-7 (5-7), 6-3 win over veteran Karlovic with the contest lasting just under two hours.

Russian Daniil Medvedev earned a second-round clash against fourth seed Fernando Verdasco as he beat Yuki Bhambri from India 6-4, 6-1.
