He will face sixth-seeded American Mackenzie McDonald in the quarterfinals after McDonald rallied past Belgium’s Kimmer Coppejans 4-6, 6-3, 6-2.
No. 8 seed Yoshihito Nishioka of Japan got past South African Lloyd Harris 7-6 (4), 7-6 (5), and No. 3 seed Jan-Lennard Struff of Germany outlasted Chile’s Cristian Garin 6-3, 1-6, 6-4. Nishioka and Struff will meet in the quarters.
