Emma Raducanu recorded the quickest victory of her professional career, dispatching Indonesian qualifier Janice Tjen 6-2, 6-1 in exactly one hour to reach the U.S. Open third round. The 22-year-old Briton struck eight aces, did not face a break point and improved her 2025 record to 26–10. She will meet either 2022 Wimbledon champion Elena Rybakina or Czech teenager Tereza Valentova in the last 32. Defending champion Aryna Sabalenka overcame a sluggish start to defeat Russia’s Polina Kudermetova 7-6 (4), 6-2. The world No.1 now faces 2021 runner-up Leylah Fernandez in a rematch of their semi-final four years ago, as she bids to become the first woman since Serena Williams in 2014 to retain the New York crown. World No.2 Iga Swiatek was pushed to three sets by Dutch No.66 Suzan Lamens before prevailing 6-1, 4-6, 6-4. The Pole extended her streak of reaching at least the third round at every major this decade and notched her 51st tour-level win of the season. Swiatek next plays Russia’s Anna Kalinskaya. On the men’s side, second seed Carlos Alcaraz needed just 96 minutes to dismiss Italy’s Mattia Bellucci 6-1, 6-0, 6-3, finishing with 32 winners and no breaks conceded. Andrey Rublev also progressed, while France enjoyed a perfect day as qualifier Ugo Blanchet stunned No.16 seed Jakub Mensik in five sets and veterans Benjamin Bonzi, Arthur Rinderknech and Adrian Mannarino all advanced. The flurry of results leaves several former champions and rising contenders on course for enticing third-round match-ups as the season’s final Grand Slam enters its first weekend in Flushing Meadows.
