After securing the win over his 20-year-old opponent, the world No 1 will now face Matteo Berrettini in the quarterfinals, in what will be a rematch of the recent Wimbledon final.
Djokovic was “excited” to meet the world No 8, who had played just one tournament between Wimbledon and the US Open, much like the Serb himself.
“Rematch from Wimbledon final from a couple of months ago,” the top seed noted.
“It’s going to be exciting. He loves the big stage.
“Matteo is already established in top ten. Big serve, big game overall. I will try to prepare and hope for the best.”
