Coco Gauff, the 20-year-old tennis star and flag bearer for the U.S., faced a heartbreaking exit from the Paris Olympics after being defeated by Croatia's Donna Vekic 7-6(9), 6-2. The match was marred by a controversial call that led to a tearful confrontation with the chair umpire, where Gauff expressed her frustration over feeling unfairly treated. Meanwhile, Rafael Nadal and Carlos Alcaraz advanced in men's doubles, overcoming a tough match against Dutch players to keep Nadal's hopes for a third Olympic gold alive. Gauff, who recently won the U.S. Open, indicated she would focus on recovery and preparation for the upcoming U.S. swing. The Olympic experience was bittersweet for Gauff, who showed great promise but fell short in her matches. Nadal's future in tennis remains uncertain as he contemplates his career after the Olympics.
