Australian Open protests place chiefs on alert as star goes on ‘disrespect’ rant

Jannik Sinner isn’t resting on his laurels ahead of a second consecutive Australian Open semi-final.

The reigning champion is set to take on Ben Shelton in tomorrow’s last-four clash, but the Italian claims his head is screwed firmly on.

He said: “Every time is different, no? The first times you always remember. And then when you do it again, you’re still very, very happy to be here, no?

“You know, we just never take things for granted. I’m happy to be here. I’m happy trying to bring some good tennis when it counts, and that’s it, no?

“I like the conditions here to play, and the crowd is amazing. It was very respectful today. Knowing that playing against Alex here, it’s not easy. You know, I’m just trying to enjoy this moment, and then we see how it goes.”
