[Reporter Liang Weiming/Comprehensive Report] Amanda Anisimova, the women's singles runner-up at last year's US Open, suffered an upset defeat in the third round this year. She lost to Anastasia Potapova, a Russian-born Austrian, 2:6, 5:7. The 10th seed in the women's singles, who had a landlord advantage, was eliminated early and had no chance to repeat the glory of the last year's finals.

"I feel like I'm the happiest person here. Maybe the coach is happier than me." Potapova saved 13 of the 16 break points. She stabilized and extinguished the fire in the second set. It took 1 hour and 39 minutes to defeat Anisimova in straight 2, and entered the New York Grand Slam for the first time in her career. After the fourth round, she covered her mouth in excitement and said: "Every time I step on this court and face so many spectators, I get goosebumps with excitement." As for Potapova's next opponent, she will be the new French Open champion and Russian fifth seed Andreeva (Mirra Andreeva), with 1 win and 3 losses in the past games and was at the disadvantage.

Anisimova, who was also the runner-up at Wimbledon last year, has fallen into a slump this season and has not yet qualified for any championship match. The 46 unforced errors she made in this campaign were even more fatal. Especially after losing the first set, her constant communication with her coach failed to produce any results, which made her very frustrated for a time.
