The first of the US Open fourth-round matches take place on day seven of the New York City Grand Slam tournament on Sunday.

Novak Djokovic, who had to fight back from two sets down to progress in round three, tops the bill for the men – while, in the women’s singles, sixth-seed Coco Gauff is the latest player charged with fending off the brilliant return to top-class action of former world No.1 Caroline Wozniacki.

We have combined three bets in our day seven accumulator, which sees us expecting a tough test for in-form American Tommy Paul.

Ben Shelton to beat Tommy Paul @ 9/4

Bryan Shelton’s best performance in a Grand Slam tournament came when reaching the fourth round of Wimbledon in 1994, but his son Ben has a chance to better his dad’s best effort when he plays Tommy Paul for a place in the quarter-finals of the US Open on day seven in New York City.

Shelton junior looks the full package in terms of potential and it would be no surprise seeing his name being engraved on to a major trophy in the near future.

Unsurprisingly, he’s an outsider to beat Paul, who held sway in four close sets in the Australian Open at Melbourne Park in January.

But don’t be surprised, with Shelton packing plenty of power into his game, if the Atlanta native comes up trumps in their second meeting at Flushing Meadows.

It looks set to be a cracker – and it’s unlikely to be over quickly given that Paul is in fine form himself. But the draw looks wide open now for a player of Shelton’s potential to exploit and he looks a good price to upset his more experienced opponent.

Belinda Bencic to beat Sorana Cirstea @ 4/7

Sorana Cirstea, 33, looks to be playing at or near the peak of her powers, but even that may not be enough to deny Belinda Bencic the opportunity to progress to the quarter-finals of the year’s final Grand Slam tournament.

Bencic, 26, should now be in her physical prime and she’s definitely one of the best players never to have won a Slam singles title.

Whether or not the Swiss can ditch her maiden tag in 2023 is obviously open to question, but she may have a slightly better chance of doing so than her outright price suggests and she did go all the way to the gold medal in the Tokyo Olympics in 2021.

It’s 2-1 to Bencic in the pair’s personal series and Cirstea won their last meeting, but the favourite can be included in today’s acca because this is a match she should really be winning.

Coco Gauff to beat Caroline Wozniacki @ 2/11

Caroline Wozniacki has worked wonders to see off Petra Kvitova and Jennifer Brady on her return to top-class tennis, but perhaps we shouldn’t be that surprised by the Dane’s effort in her first Grand Slam tournament since announcing her retirement from her chosen sport was over.

Wozniacki, 33, retired from tennis in 2020 but let’s not forget that the long-time world No. 1 did finally manage to get her hands on a major singles crown in the 2018 Australian Open.

After a break of more than three years, Wozniacki is back and loving life on court. She could bring her vast experience to bear against Coco Gauff but it’s likelier that, with the game having moved on in the meantime, the in-form American will win the day.

Gauff has recently won US Open Series titles in Washington DC and Cincinnati, triumphs which suggest she may finally be ready to claim her first major singles title.

And if that is still the case, then she will need to be strong enough temperamentally to see off former top woman Wozniacki, who, unsurprisingly, she never played before the Dane’s lengthy hiatus.
