CNN —Jessica Pegula advanced to the fourth round of the US Open with a hard fought 6-4 4-6 6-2 victory over Ukraine’s Elina Svitolina, continuing the impressive performances of American players at their home tournament. 3 seed will now face her compatriot Madison Keys for a place in the quarterfinals after Keys completed a 5-7 6-2 6-2 victory over Russia’s Liudmila Samsonova in her own third-round match. She really picked up her level and forced me to go after that third set.”Remarkably, Pegula has also reached the fourth round in both the doubles and mixed doubles at Flushing Meadows. Robert Prange/Getty ImagesPeyton Stearns will also join her compatriots in the fourth round after she defeated Britain’s Katie Boulter to reach this stage of a grand slam for the first time in her career. But with Pegula, Keys, Stearns and Coco Gauff all reaching the fourth round and with Taylor Fritz, Frances Tiafoe, Tommy Paul and Ben Shelton all still in contention in the men’s draw, American tennis seems to be flourishing again.
