US Open: Sinner obliterates Bublik to set up all-Italian quarter-final with Musetti | Jannik Sinner

Jannik Sinner claimed his quickest grand slam victory with a brutal destruction of Alexander Bublik in the fourth round of the US Open.

The world No 1 had looked a little vulnerable in the previous round, when he dropped his first set of the tournament to Denis Shapovalov, but he needed just an hour and 21 minutes to race to a 6-1, 6-1, 6-1 win against Bublik.

The unpredictable Kazakh is the only player other than Carlos Alcaraz to have beaten Sinner in the last 12 months, doing so on grass in Halle. In his pre-match interview Bublik said his goal was not to lose his first service game, but he did just that and did not help himself with 13 double faults – including one featuring two underarm serves in the first set – as he dropped serve a further seven times. There were also far too many errors off the ground from Bublik, who at least raised his level in the third set only for Sinner to reply with interest.

Bublik could do nothing but smile at some of the winners from the defending champion, although the fans who had paid hundreds of dollars for a ticket may not have felt quite so appreciative.

Sinner cited Bublik’s long battle with Tommy Paul in the previous round in mitigation, saying: “He had a very tough match the last match. He didn’t serve as well as he usually does. I’m very happy. The first time this year I can play the night match here and it makes so, so big difference.”

Sinner’s winning run at hard-court grand slams now stands at 25 matches – only two short of Novak Djokovic’s best – and he will take on Lorenzo Musetti in the last eight in the first all-Italian men’s quarter-final at a grand slam.

“It’s great to see,” said the top seed. “Italian tennis is in great form now. Lorenzo is maybe one of the biggest talents we have in our sport. From an Italian point of view, it’s great to have one Italian player in the semis.”

Tenth seed Musetti is having his best run at Flushing Meadows and was almost as dominant as Sinner, beating Spain’s Jaume Munar 6-3, 6-0, 6-1.

Alex De Minaur hopes he can finally break through the grand slam quarter-final barrier after setting up a last-eight clash with Felix Auger-Aliassime earlier in the day. The Australian is through to this round for the fifth time in his last seven major tournaments and sixth time overall, but he has never been further.

In the other men’s quarter-finals, Novak Djokovic will face home hope Taylor Fritz, while the 2022 champion, Carlos Alcaraz, plays Jiri Lehecka of the Czech Republic.
