Coco Gauff furiously contests umpire’s decision during Olympic tennis singles defeat

This is the moment Coco Gauff furiously contests an umpire’s decision during her shock defeat to Donna Vekic in the Olympic women’s singles.

Gauff had led 5-2 in the opening set on Tuesday (30 July), but Croatian Vekic fought back and then broke for 4-2 in the second on a contentious point.

The umpire over-ruled a Vekic shot that had been called out and awarded her the point after deciding Gauff, who subsequently missed her shot, had not been affected by the call.

Gauff, who experienced a similar situation at the French Open, complained bitterly to the umpire and supervisor, claiming she was being “cheated”.

A tearful Gauff said: “It always happens to me on this court... I have to advocate for myself every time.”
