Third seed Daniil Medvedev once again worked the U.S. Open graveyard shift on Saturday, beating in-form Sebastian Baez 6-2 6-2 7-6(6) to end the Argentine's 12 match winning streak.
Against the 26th seeded Evans the 20-year-old Spaniard mixed moments of brilliance with lapses in focus but was never really threatened on his way to 6-2 6-3 4-6 6-3 win.
Top seeded Briton, number 16 Cameron Norrie, was dumped out 6-3 6-4 6-3 by Italian Matteo Arnaldi while American Peyton Stearns pushed the last British woman Katie Boulter to the exit with a 6-4 6-3 victory.
Joining Pegula were 2017 finalist Madison Keys, a 5-7 6-2 6-2 winner over 14th seed Liudmila Samsonova, Stearns and sixth seed Coco Gauff, who booked her spot on Friday with a win over Elise Mertens.
