'Are you kidding me? That's the biggest let ever' - Alexander Zverev left infuriated at the umpire after confronting him on perceived let

Alexander Zverev was furious with the umpire at the Laver Cup after a decision did not go his way in the singles match against Alex de Minaur.

Team Europe had got off to a brilliant start on day one, with Casper Ruud and Jakub Mensik picking up wins against Reilly Opelka and Alex Michelsen in the singles. Joao Fonseca became the youngest player to feature at the Laver Cup, and got Team World's first points on the board with a win over Flavio Cobolli.

Europe extended their lead back to two in the doubles, as the recently crowned US Open champion and world number one, Carlos Alcaraz, stepped onto the court for the first time, partnered with Jakub Mensik. It was a tight match between American number one Taylor Fritz and Michelsen, but they managed to get over the line to give them a 3-1 lead.

On the second day, each win gets you two points. This meant that de Minaur could level the scoreline with a win over his German opponent.

Zverev left furious on court

The Australian recently reached the quarter-final of the US Open, and continued that good form in San Francisco, taking a commanding 5-0 lead over Zverev, which included two break points clinically taken from two opportunitites. Zverev stopped the rot to make it 5-1, but the world number eight had no problem in serving it out to give his team a set advantage.

The first six games of the second set went on serve before de Minaur once again took the advantage by breaking. This time, he could not extend his advantage as Zverev took his third break point to level the score at 4-4. While serving when 15-30 down, he made no attempt to return the de Minaur shot, pointing to the net. He was adamant that there was a let, but the umpire was not on the same wavelength as the world number three.

In a state of fury, Zverev approached the umpire and shouted at him: "Every single person here saw that. Are you kidding me? That's the biggest let ever."

"The ball hit the ground to the side, how do you not see that? Every person (could see it)." The umpire apoligised to the German, but he was in no mood in accepting it. "Are you kidding me? Are you serious?"

Zverev would save the two resulting break points, but eventually would succumb his serve to de Minaur, who clinched the tie with his first match point, in a monunentous victory for Team World.

Team World extract hefty lead

From then on, it does not get any better for Team Europe. Holger Rune was defeated by Argentine Francisco Cerundolo. The world number 21 found a break halfway through the first set, wrapping it u[ with little fuss. He went on to break once more at the start of the second set, before being pegged back by the Dane.

Rune squandered a set point to level the tie, leading it to a tiebreaker. The score was level at 5-5, before Cerundolo managed to squeeze in front, and win it to confirm another haul of points for Team World.

This was followed by Alcaraz losing his first singles match since the Wimbledon final, against Fritz. The world number four survived early break points, before claiming one of his own. He held serve for the rest of the set, before winning the last four games of the second set to seal the victory, and his first win against the Spaniard.

Team World completed the clean sweep on day two after winning the doubles tie 6-3, 6-4. Michelsen and de Minaur were too strong for Ruud and Rune, earning another two points which sees them in the elad with a 9-3 advantage. Team Europe will have some work to do if they want to regain their title they won last year.
