This was the refereeing error that made Alexander Zverev lose a set

Alexander Zverev secured the victory in a duel against Hugo Gaston at the ATP Hamburg 2024. However, the Frenchman took the first set thanks to a double bounce on the set point that the chair umpire did not see. The German protested the action, but faced with Gaston’s denial, who insisted it was only one bounce and the umpire’s decision, Zverev flew into a rage and called the supervisor who couldn’t intervene against the referee’s ruling. “It’s impossible that I only bounced once, impossible!“, exclaimed the Hamburg tennis player. Despite this and despite the evidence of the double bounce, he managed to regroup and turn the match around to advance to the quarterfinals.
