Coco Gauff suffered a surprising exit from the US Open, losing to fellow American Emma Navarro in the fourth round, marked by 19 double faults and 60 unforced errors, with a final score of 6-3, 4-6, 6-3. This defeat means Gauff remains unable to defend the title, leaving Serena Williams as the last woman to do so in 2014. Navarro, who previously defeated Gauff at Wimbledon, expressed her excitement about reaching the quarter-finals, stating, 'this is the city I was born in and it feels so special to be playing here.' The tournament has also seen the early exits of defending men's champion Novak Djokovic and last year's winner Carlos Alcaraz, further diminishing hopes for a homegrown champion. Frances Tiafoe and Taylor Fritz have advanced to the men's quarter-finals, reigniting hopes for an American male Grand Slam champion since 2003. Paula Badosa also reached her first US Open quarter-final with a dominant win over Wang Yafan.
