No. 6 seed Jessica Pegula stunned top-seeded Iga Swiatek in the US Open quarterfinals Wednesday night, punching the fourth ticket for an American into the tournament's semifinals.
With the win, Pegula advanced to the semifinals of a Grand Slam tournament for the first time in her career. There, she'll join fellow Americans Emma Navarro, Frances Tiafoe and Taylor Fritz. She'll face unseeded Karolína Muchová for a berth in the championship match.
