The O2 erupts into boos as Alexander Zverev and Alex De Minaur shocked

The O2 Arena, where the Laver Cup tennis tournament is being staged, saw its crowd erupt into a chorus of boos during the third set of Alex De Minaur's victory over Alexander Zverev. The umpire bizarrely called a 'let', meaning the serve is replayed, even though the serve did not hit the net cord, leaving fans and both players baffled.

A let is typically only called when a served ball hits the top of the net and lands cleanly inside the correct service box. However, that was not the case on this occasion, as the umpire ordered the serve to be played again even though the ball landed out, causing the entire crowd to jeer the decision and demand an explanation.

Zverev and De Minaur were both audibly complaining to the official, who was forced to speak into their microphone and explain that the point was being replayed because the scoreboard had accidentally ticked over and confirmed a point before it was awarded by the umpire.

The contentious moment came during the third set, which consists of a super tiebreak at the London event, which is considered an exhibition but features many of the ATP Tour's top names playing in a competitive atmosphere.

They took the lead over Team Europe, with Zverev dropping valuable points before Carlos Alcaraz takes to the stage to face Fritz.

But Zverev appeared to be visibly frustrated at the end of the match, likely in part due to his collapse, but also having been forced out of his rhythm at such a crucial moment by a scoreboard error.

De Minaur was given a roaring cheer when he sealed an unlikely comeback over the 2026 French and US Open champion.

And the Aussie addressed the very late incident, saying: "I mean, my opinion on the let call is it's a let call, right? The rules are the rules."

He added: "So they called it a let call because the screen went... So the rules are you've got to play two, but obviously I would have loved to play that point with a second serve instead of giving him another first serve.

"It was unfortunate, but I tried to do my best for it not to rattle me and kind of stay in the moment, and I managed to pick the right way, and it ended up working out. So happy days. If it hadn't worked out, then maybe I would have a different opinion on it."
