Bianca Andreescu defeated Zeynep Sonmez 6–4, 6–4 in the first round of the WTA 250 event at 's Hertogenbosch on grass on 13 June 2023, as expected given her status as a clear pre-match favourite with odds of 1.21 to Sonmez's 4.93. Andreescu's composed performance on the Dutch grass court demonstrated control throughout both sets, with the Canadian securing breaks at crucial moments to close out the match in straight sets. The victory underscores Andreescu's continued adaptation to grass-court tennis as she progresses through the early rounds of the tournament ahead of Wimbledon.
