Coco Gauff loses an argument with the chair umpire and a match to Donna Vekic at the Paris Olympics
She hit a serve and Vekic's return landed near the baseline. A line judge initially called Vekic's shot out; Gauff did not keep the ball in play. Chair umpire Jaume Campistol thought Vekic's shot landed in and awarded her the point, giving her a service break and a 4-2 lead.
