Sinner's 6-2 6-3 victory in one hour and 28 minutes saw him go level with Novak Djokovic for the longest stretch without defeat in the format, while also reaching the quarter-finals. 

The top seed wasted little time settling into his groove as he opened up with back-to-back breaks of serve to surge into an early 4-0 lead. 

Pellegrino was able to get himself on the board, but the damage had already been done by Sinner, who comfortably finished the first set with a love service game.

Sinner missed the chance to get the better of his opponent's serve in the opening game of the second, with Pellegrino more than matching the world number one for the majority. 

However, a timely break in the seventh game was all that Sinner needed as he sealed his progression against the serve, after Pellegrino sent a backhand long. 

Sinner will now face either Andrey Rublev or qualifier Nikoloz Basilashvili for a spot in the semi-finals, as the four-time grand slam champion edges closer to making more history.
