Emma Navarro and Coco Gauff

Emma Navarro achieved a remarkable upset by defeating defending champion Coco Gauff 6-3, 4-6, 6-3 in the fourth round of the U.S. Open, marking her second consecutive Grand Slam victory over Gauff. Gauff's performance was marred by an alarming 19 double faults and 60 unforced errors, leading to her elimination and a drop from the top five in world rankings. Navarro, who has shown significant improvement this year, will face Spain's Paula Badosa in the quarter-finals. Gauff's struggle with her serve and forehand under pressure raises concerns about her performance moving forward. Navarro expressed her respect for Gauff, acknowledging her as an exceptional player who will likely rebound in future tournaments. This match highlights the unpredictability of tennis, especially following the earlier surprising exit of men's champion Novak Djokovic.
