Coco Gauff, a 19-year-old from Florida, reached her first final at Flushing Meadows by defeating Muchova 6-4, 7-5 on what was anything but an ordinary evening.
“I really believe that now I have the maturity and ability to do it,” said Gauff, who came close to a major trophy at last year’s French Open but lost the title match. “You know, regardless of what happens on Saturday, I’m really proud of how I have been handling the last few weeks.”
The No. 6-seeded Gauff will meet No. 2 Aryna Sabalenka of Belarus for the championship Saturday. Sabalenka defeated 2017 U.S. Open runner-up Madison Keys 0-6, 7-6 (1), 7-6 (10-5) in a topsy-turvy second semifinal that finished at nearly 1 a.m.
