Carlos Alcaraz faces a stiff test in his bid to defend the US Open as he faces former finalist Alexander Zverev for a place in the last four.
“Against Sascha, the head-to-head as well is really, really close,” he said “We’ve played great matches. He’s playing really, really well. This year he’s finding his top level again.”
The winner of that match will play whoever triumphs in the all-Russian tie between close friends Daniil Medvedev and Andrey Rublev.
In the women’s draw, second seed Aryna Sabalenka, who will become world No 1 at the end of the tournament, plays Qinwen Zheng of China.
The night session on Arthur Ashe is opened by the clash between Wimbledon champion Marketa Vondrousova and home favourite Madison Keys.

Iga Swiatek won her third major as she beat Ons Jabeur 6–2, 7–6. Swiatek was knocked out this year by Jelena Ostapenko, who said afterward that she had found Swiatek’s Achilles’ heel.
