Defending champion Coco Gauff was eliminated from the US Open in the fourth round by compatriot Emma Navarro, who won the match 6-3, 4-6, 6-3. Gauff, the third seed, struggled with 19 double faults and 60 unforced errors, continuing a trend of inconsistent play that has plagued her season. Navarro, ranked 13th, showcased her strength and composure, breaking Gauff's serve multiple times and regaining momentum after losing the second set. This victory marks Navarro's second win over Gauff in a Grand Slam this year, having previously defeated her at Wimbledon. Navarro will advance to the quarterfinals to face Spain's Paula Badosa, while Gauff's exit means she will drop out of the top five in world rankings, a significant shift for the 20-year-old star. The loss of Gauff adds to the unpredictable narrative of the US Open, where other top players like Novak Djokovic and Carlos Alcaraz have also been eliminated.
