Jannik Sinner offered an insight into his private text conversations with Jack Draper after setting up a semi-final meeting with the Brit at the US Open. Sinner made light work of Daniil Medvedev to secure his place in the last four at Flushing Meadows, where he is the favourite to win the title.

The Italian already knows Draper well, having played alongside him in doubles at the Canadian Open last month. However, they will be forced to put their friendship to one side when they go up against each other for a place in the US Open final.

Speaking after his victory over Medvedev, Sinner revealed that he often exchanges text messages with Draper as he opened up on their bond outside of tennis.

“It was nice to share the court with him in doubles in Montreal,” he said. “We got to know each other even more. We text each other when we have good or bad times, trying to keep us up. It’s a great friendship.

“Obviously, we try to put this away for the hours we are on court. I think that’s quite obvious but, you know, whenever we shake our hands we get our friendship back and it’s always going to be good.”

Draper also recently spoke about his bond with Sinner, vowing to stay in touch regardless of what happens in New York later this week.

“We’ve always kept in touch since I’ve been on tour the last couple of years,” said the Brit. “Jannik is a good friend, someone I’m definitely close to. We send each other messages in good moments, bad moments.

“It’s a tough sport to play when you’re a young guy. You’re kind of, you’re on the road, you’re playing such a relentlessly intense sport, both physically, emotionally, and it’s difficult, we haven’t got many friends.

“To have the support of someone who’s going through it themselves is really big. So, yeah, huge respect for Jannik and it was amazing to play doubles with him in Montreal. I think we played great doubles together.

“I’d never won a doubles match on the tour, so to play obviously with the No. 1 player in the world was amazing and definitely learned a lot about playing doubles and had a lot of fun with him.

“It was really nice to be able to step out on court with him. Yeah, I’m sure we will continue to stay in touch.”
