Continuing her remarkable summer streak, Gauff triumphed over Muchova with a scoreline of 6-4, 7-5 on Thursday night, securing her inaugural berth in the women's singles final at the Flushing Meadows.
Having won Auckland in January and Washington D.C. two weeks ago, Gauff is now the first teenager to win three titles in a season since Bianca Andreescu in 2019.
Iga Swiatek built a big lead in the French Open final, then overcame a second-set crisis of confidence and a third-set deficit before righting herself and defeating Karolina Muchova 6-2, 5-7, 6-4
Barty lost the match 1-6, 6-3, 6-2 as Muchova continued taking down higher ranked opponents. She had earlier beaten her compatriot and world No.1 6 Karolina Pliskova before beating 18th ranked Elise Mertens of Belgium in the fourth round.
