High-profile former champions Emma Raducanu, Naomi Osaka and Coco Gauff all moved safely into the third round of the US Open in New York, offering early intrigue in the women’s draw. Britain’s Raducanu backed up her 6-1, 6-2 first-round dismissal of Japan’s Ena Shibahara with a similarly one-sided 6-2, 6-1 victory over Indonesian qualifier Janice Tjen. The 22-year-old, who lifted the trophy as a teenager in 2021, recorded her first wins at Flushing Meadows since that title run and has yet to drop more than two games in a set this week. Four-time major winner Osaka also revived memories of past success, easing past Belgium’s Greet Minnen 6-3, 6-4 before overwhelming American Hailey Baptiste 6-3, 6-1. Seeded No. 23, the Japanese star is into the tournament’s last 32 for the first time since 2021 and credited new coach Tomasz Wiktorowski for improved shot placement and consistency. Home favourite Gauff, champion here two years ago, required nearly three hours to oust Ajla Tomljanovic 6-4, 6-7(2), 7-5 in her opener, then overcame serving struggles and early nerves to defeat Croatia’s Donna Vekic 7-6(5), 6-2. The 21-year-old American has now won 12 of her past 13 matches at the event, although double faults remain a concern. Raducanu next faces either Elena Rybakina or Tereza Valentova, Osaka awaits the winner of Daria Kasatkina’s clash with Kamilla Rakhimova, and Gauff meets Poland’s Magdalena Fręch as the trio seek deeper runs at the season’s final Grand Slam.
