Coco Gauff faced a controversial line call during her third-round match against Donna Vekic at the 2024 Paris Olympics, resulting in an emotional and heated argument with chair umpire Jaume Campistol. The incident occurred when a return from Vekic was initially called out, but later overruled by the chair umpire, awarding the point to Vekic. Gauff argued that the call affected her shot, but the umpire disagreed, leading to a significant delay and Gauff being visibly upset. Despite this, Gauff admitted that the disputed point was not the sole reason for her defeat, as she was already trailing. The episode has reignited calls for the introduction of video review systems in tennis to handle such contentious decisions. Gauff continues to compete in the doubles and mixed doubles events at the Olympics.
