Wow, what a showdown at Arthur Ashe! Queen Naomi Osaka turned back the clock and took down her 'little sis' Coco Gauff in straight sets, 6-3, 6-2, to reach the US Open quarters. Gauff’s serve woes and unforced errors really cost her, while Osaka played patient, smart tennis. This rivalry keeps delivering drama—Osaka’s now 2-0 against Gauff at the US Open. Can she keep her Grand Slam quarterfinal streak alive? #Sports #Tennis #USOpen
