Jannik Sinner required just 81 minutes to crush Alexander Bublik 6-1 6-1 6-1 and return to the US Open quarter-finals.
Bublik was the last player to beat Sinner, recording a victory on grass at Halle shortly before Wimbledon, and the World No1 showed no mercy as he destroyed his opponent in the night session on Arthur Ashe Stadium, allowing just three games.
