Billie Jean King Cup: Former World No.1 Naomi Osaka kicked off her grass-court season with a win at the Libema Open, defeating No.32 Elise Mertens in straight sets in the first round on Tuesday. Osaka defeated Mertens 6-2, 6-4 to register her first win on grass since the 2019 Wimbledon.

Making her tournament debut in Rosmalen, Osaka made good of the wild card into the main draw of the event.

Following up on her outstanding performance in the second round of the French Open, where she held match point on eventual champion Iga Swiatek, Osaka's sublime serving and crisp baseline hitting was once again on full display in the 70-minute victory.
