De Minaur struggled against Zverev throughout their 6-4 7-6 6-4 match, but he will also be cursing himself after missing golden opportunities to take the second set.
Zverev landed his first blow of the encounter before the match even began when he appeared to rob de Minaur of a chance to choose if he would serve or receive.

Zverev was seen handing the coin back to chair umpire Damien Dumus before the official looked towards the Australian to make the decision and said: “You tell me, Alex”.
However, Zverev then jumped in to say: “No, I said racquet”.

Zverev then looked to de Minaur and said: “But if you want to go, you go. I’ll receive.

Leading tennis journalist Ben Rothenberg wrote: “I have never seen such casual, committed in tennis like this before”
Tennis fan account ‘Tennis Blockade’ also captured the video, writing: “Zverev lying, scamming and gaslighting… during a coin toss, this time.
