The Italian came into the Labour Day evening clash at Arthur Ashe Stadium looking for his 25th straight major match win on his preferred surface and he never looked in any trouble against a tricky opponent after shooting out of the blocks.

“He (Bublik) had a tough match last time, finishing late. He didn’t serve as well as he does. I broke him in every set, and it gave me the confidence to play well,” the top seed said.

“My first night session match, it makes such a difference. Thanks everyone for coming, this is such a special occasion for us players.”

Sinner built a 4-0 lead before the Kazakh could even get on the board. Soon after, the dominant 24-year-old chased down a drop shot to fire home a backhand winner that wrapped up the opening set.

Bublik’s attempts to disrupt Sinner’s rhythm with more drop shots proved futile, but it was his service errors that left him trailing by two sets before Sinner wheeled away to his eighth straight major quarterfinal and a clash with compatriot Lorenzo Musetti.

Musetti, the 10th seed, earlier booked his last-eight place with a comfortable dismissal of Jaume Munar, 6-3 6-0 6-1.
