US Open live: Jannik Sinner battles Lorenzo Musetti after Amanda Anisimova stuns Iga Swiatek to set up Naomi Osaka semi-final

He marches through five games in 20 minutes, holding to love.

Pretty ominous for Musetti.

Big, big trouble for Musetti, who has been able to crack a few forehands at Sinner but is seeing everything being returned with interest so far.

A forehand is powered down low at Musetti’s backhand and it seals the second break.

A string of errors from Musetti, whose one-handed backhand is already the target of Sinner’s fierce strike, and the defending champion gets the opening break already.

This is the first all-Italian grand slam quarter-final in history.

The good news for Sinner is he has a 15-0 record against Italian players.

The defending champion fires back-to-back aces to get us started.

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.

Bublik was left celebrating as he won a game in the third set. The 28-year-old almost fell into Sinner’s arms at the net and had the World No 1 laughing along when he said to him: “That was so good. I’m not so bad, but you’re the GOAT”.

Jannik Sinner is on a 25-match winning streak at the hard-court grand slams and was on dominant form in beating Alexander Bublik 6-1 6-1 6-1 in the fourth round.

He plays fellow Italian Lorenzo Musetti for the first time in two years. Musetti is through to the US Open quarter-finals for the first time, his best result at a hard-court major.

Naomi Osaka just wanted an opportunity to get back the US Open after giving birth to her first child two years ago.

Here she is, back in a grand slam semi-final for the first time since winning the Australian Open in 2021.

Naomi Osaka is back in the US Open semi-finals! The two-time champion takes down the spirited efforts of Karolina Muchova, winning 6-4 7-6 (7-3) to set up a mouthwatering clash with Amanda Anisimova.

A great effort from Muchova, who required treatment after the first set but battled on. But what a result for Osaka, who is back in the US Open semi-finals for the first time in five years!

She is back! An emotional win for Osaka.

Muchova lost just six points on serve in the first set against Osaka.

They all came in the final game as Osaka broke to love to take the opening set of their quarter-final.

Muchova was cruising through the service games, but Osaka strikes when it counts.

And Muchova has also called the trainer, heading off court for treatment.

Amanda Anisimova says she hopes the way she bounced back from the Wimbledon final defeat sends a positive message on her to respond to difficult moments.

“I feel like I was really able to bounce back from it really quickly,” she said. “Maybe a few years ago I wouldn’t have done the same as well as I have this time but it’s definitely nothing I’ve ever experienced before. I never lost 6-0, 6-0, and then to lose 6-0 6-0 in a Grand Slam final was a lot to experience.

“Today I’m just really, really proud of myself. I feel like I really made a point to myself and also maybe to other people that, like, if you really put a positive mindset out there or just try and work through things, then you can have a positive outcome. I feel like I was really able to do all the right things, so I’m really happy.”
