Naomi Osaka made a strong return to the US Open by defeating No. 10 Jelena Ostapenko 6-3, 6-2 in just 64 minutes, showcasing her previous championship form despite a year-long maternity leave. This victory marks Osaka's impressive comeback after facing personal challenges, including mental health breaks and struggles to regain her competitive edge. Meanwhile, top-ranked Iga Swiatek had a tougher match, narrowly defeating Kamilla Rakhimova 6-4, 7-6 (8-6), maintaining her strong record in first-round Grand Slam matches at 22-1. Danielle Collins' singles career at Grand Slams concluded with an upset loss to Caroline Dolehide, while Jannik Sinner, the men's No. 1 seed, returned to action following drug test controversies. Additionally, notable players like Stefanos Tsitsipas and Felix Auger-Aliassime were eliminated in the first round. Both Osaka and Swiatek's performances highlight the competitive landscape of this year's tournament.
