BBC commentator Katherine Downes said: "I think they're asking for a replacement for one of the court team. I don't know whether it's the ball kids. Someone has been removed from court for feeling dizzy and is spending some time in the shade.

"The umpire is just calling up to ask for a replacement and somebody to come and give assistance to the member of staff."

Boucharinc announced to spectators inside Court 18: "Ladies and gentlemen we're just waiting for one ball boy to replace someone who was not feeling well. We'll return to play as soon as the ballboy comes back."

With no replacement quickly available, the umpire decided to reorganise the ball kids himself as they were a person light.

He added: "I think this is what we're going to do actually. We need someone from the back on the receiver's side who will come to the net. Can we do that? OK, perfect, alright."

Downes told viewers at home: "Louis Boucharinc is going to rearrange the layout of the ball kids to make sure the match can resume. They're not going to bother waiting for a full replacement."

The match continued as De Minaur took the third set to a tiebreak - which he won 7-2. The Australian takes on the winner of Arthur Cazaux vs Adam Walton in round two.

Ahead of that match, De Minaur said: "Yeah, I've hit with Adam a bit. We went on junior tours together, so I've known Adam for a very long time.

"Arthur I know less. He's obviously very talented. He's had some big scalps before. He's coming through quallies and playing with a lot of confidence.

"I think, again, it's going to be another battle, and for me if I can come out and bring the level that I know I can bring, then I'm giving myself a good shot. That's the only thing I'm kind of worried about."
