Alexander Bublik could not believe what he saw from Jannik Sinner after the defending US Open champion marched into the quarter-finals with a 6-1 6-1 6-1 win against him in just 82 minutes.
Bublik was the last player to beat Sinner, and the only player other than Carlos Alcaraz to win against him this season, when he did so on grass at Halle shortly before Wimbledon in June.
