Sinner outclasses Musetti at the US Open

Jannik Sinner maintained his perfect record against his fellow Italians with victory over Lorenzo Musetti to reach the US Open semi-finals.

The world number one has faced his countrymen 16 times at tour level and won each time, including three times against Musetti.

That never looked like changing here, with Sinner easing to a 6-1 6-4 6-2 win in exactly two hours to set up a semi-final clash against Felix Auger-Aliassime on Friday.

Musetti is yet to win a set against Sinner but so dominant is the defending champion against almost everyone on the men's tour, that is fast becoming the norm.

With victory here, Sinner became the youngest man ever to win 25 grand slam matches in a season, while he has already equalled Nicola Pietrangeli’s 86 major wins, making him the joint most successful Italian on the big stage less than a month after his 24th birthday.

It took Musetti six games just to get on the board but the second set was much tighter and the match might have headed in a different direction had the 23-year-old taken his chances.

However, Sinner saved all seven break points he faced while converting five of the six he created, and he is now just one victory away from making a fifth-straight slam final.

"It was a good performance, I was very solid, I started well... it's nearly midnight, so thank you all for staying," Sinner told the crowd afterwards.

"Obviously we know each other well," he said of Musetti.

"We're from the same country, there are so many Italians in the draw. Many Italians here so it's nice to play here. Playing Davis Cup together and stuff but you have to take the friendship away for the match. When we shake hands, everything is fine.

"It's amazing, I'm sure that back home some Italians are not sleeping. It's a special country and we have amazing support."

Standing in his way is Auger-Aliassime, who staged a New York fightback to beat Alex De Minaur 4-6 7-6 (9-7) 7-5 7-6 (7-4).
