Naomi Osaka put her French Open disappointment behind her to advance to the next round of the Libema Open after beating Elise Mertens in straight sets. 

The 26-year-old had match point against eventual winner Iga Swiatek in the second round at Roland-Garros but failed to capitalise. However, that defeat was put to the back of her mind, winning 6-2 6-4 in the Netherlands. 

Mertens matched Osaka in the opening exchanges, but the Japanese would rally to take control and win the next three games to secure an early advantage. 

She showed signs of frustration in the second set as the Belgian threatened to take the encounter to a deciding set, but Osaka remained composed to see out the victory. 

Osaka will now face either Bernarda Pera or Suzan Lamens in the next round.

The Japanese claimed her fifth victory over Mertens since their first meeting in Wuhan in 2019, but her triumph was the first encounter between the pair on a grass court.
