Andrey Rublev and Aryna Sabalenka, top seeds at the ATP and WTA Washington Open, faced tough challenges but secured their spots in the next round. Rublev, ranked eighth, overcame a slow start to defeat Luca Van Assche 4-6, 6-3, 6-4, firing 15 aces despite initially feeling off his game. Sabalenka, coming off a shoulder injury that kept her from Wimbledon, triumphed with 13 aces and 53 winners after a grueling match lasting nearly three hours. Rublev is now set to compete against France's Arthur Rinderknech, while Sabalenka will face either Victoria Azarenka or Wang Yafan. Both players are preparing for the upcoming US Open, set to begin on August 26, as Rublev aims for his 17th ATP Tour title. Their performances highlight the intensity and competitive spirit present in this year's tournament.
