Two American women will play on Thursday for spots in the U.S. Open final.
One, Coco Gauff, the No. 6 seed, will play in the semifinals against 10th-seeded Karolina Muchova of the Czech Republic. On the other side of the draw, 17th-seeded Madison Keys of the United States will face off against second-seeded Aryna Sabalenka of Belarus, this year’s Australian Open champion.
Much of the spotlight in this tournament has been on Gauff, 19, in part for how far she has advanced on the tour while still a teenager. She reached the French Open final last year, and she is the first American teenager to reach the U.
