During a match at the US Open, German tennis player Alexander Zverev complained to the chair umpire about a fan who allegedly shouted words from Germany’s Nazi-era anthem, “Deutschland Uber Alles.” Zverev informed the umpire of the situation, leading to security officials identifying and ejecting the offending fan, who was wearing a blue baseball cap. Zverev, while not letting the incident affect his game, expressed his discomfort with the fan’s behavior, given his German background and the historical significance of the anthem. The incident sparked discussions about fan behavior at the tournament, with some criticizing the atmosphere.
