American Jessica Pegula managed to shrug off that sluggish start and come back from a set and a break down to defeat Karolina Muchova 1-6, 6-4, 6-2 for a berth in the final at Flushing Meadows. The No. 6-seeded Pegula, a 30-year-old from New York, has won 15 of her past 16 matches and will meet No. 2 Aryna Sabalenka for the title on Saturday.
