During Alexander Zverev's Round of 16 match against Jannik Sinner, a fan screamed out the "most famous Hitler phrase there is" and was consequently kicked out of the US Open. Zverev defeated Sinner in straight sets, 6-4, 3-6, 6-2, 4-6, 6-3. In the middle of the fourth set, Zverev abruptly stopped play and approached the chair umpire, pointing into the stands behind them.

The umpire began shouting at the people behind him in the stands To identify the speaker. “He just said the most famous Hitler phrase there is in this world,” Zverev complained to the chair umpire. “This is unacceptable. This is unbelievable,” the player added further.

As the play resumed, Zverev won the game to go up 3-2 in the set. Then, during the interval, some security personnel approached a man seated around ten rows back at Arthur Ashe Stadium and led him off. The guards searched for the culprit for around ten minutes before he was located and asked to leave as the crowd at the venue cheered loudly to express their support.

In the longest match at the US Open this year, the German gained an early advantage on Monday night after cruising through a commanding third set, which he won 6-2 by winning four games in a row. In the fourth set as well, he was in the lead when the fan incident occurred; nevertheless, Sinner recovered and won three straight games to force a fifth set.

Zverev appeared to be in discomfort during the fourth set, but he came out strong in the last match and advanced to the quarterfinals. He made it through an absurd third game that went on for an eternity to take a 3-0 lead, and he then held on the rest of the way to take the 6-3 victory.
