They probably leave the stream on whatever happens on the court.
Is Zverev supposed to play soon ? How did you recognise him ? I ended up thinking it might be Paulo with a cap finally ^^
isn't he supposed to play in 5-10 minutes?
Yeah but no point in warming up if you cool down during the next 30 minutes. He'll probably just change shirts and go. I remember he already did that in Bercy before the Rafa match, I was lucky enough to see his short practice just before the match began.
