Jannik Sinner extended his winning run on hard courts to 25 matches with a
ruthless dismissal of Felix Auger-Aliassime in the Cincinnati Open
quarter-finals.

Playing in his first tournament since lifting his fourth grand slam title at Wimbledon, the world No 1 and defending champion powered to a 6-0 6-2 victory over Auger-Aliassime.

Auger-Aliassime had won both his previous matches against Sinner but could offer little resistance here, with the Italian beginning and ending the contest with runs of six games in a row.

Sinner has not been beaten on his favourite surface since a loss to Carlos Alcaraz in Beijing in early October last year.

He will now face either either Holger Rune or French qualifier Terence Atmane, who stunned Taylor Fritz in the previous round.

“I felt that I was returning very well,” he said.

“I think that was the key point, which gave me the confidence to serve well. I had a small drop in the second set when he broke me. It could have been a small change but I am happy I broke him back quite early.”

Second seed Alcaraz plays his quarter-final on Friday evening against Andrey Rublev, the ninth seed, with the Spaniard on the other side of the draw to Sinner. The pair therefore remain on course for a fourth final meeting of 2025, as they complete their preparations for the US Open, live on Sky Sports from August 24.
