She faced tough tests in the first two rounds, against Anhelina Kalinina and Vera Zvonareva, but managed to win both matches in three sets. Mertens played her best tennis of the tournament in the quarterfinal, when she took on fifth seed Veronika Kudermetova. The Belgian won the match 6-4, 6-1, losing serve just once in a clinical display.
