Coco Gauff has already got support of British tennis star after demanding rule change

Coco Gauff demanded the introduction of video replays after arguing with the chair umpire during her French Open semi-final defeat. Gauff was reduced to tears over a controversial call before being knocked out by Iga Swiatek on Thursday.

The American third seed, who won her first Grand Slam at the US Open in September, missed a return on Swiatek’s serve at 2-1 up in the second set. A line judge had called ‘out’ before Gauff completed her attempt - and drama ensued when umpire Aurlie Tourte reversed the line judge’s call.

Gauff became embroiled in a heated debate with Tourte, who was adamant that the 20-year-old sensation’s shot was not affected by the call. "He called it and then I hit it. I'm a thousand per cent sure," Gauff raged.

"If he called it before I hit it, I stop my reaction. I didn't even finish my follow-through. They [the Court Philippe Chatrier crowd] are booing because you're wrong.

"This is the second time this has happened. You should be ashamed. It's a Grand Slam semi-final, know the rules of the game."

She wiped her tears away at the baseline, composing herself to break Swiatek in that game, but ultimately lost out 6-2 6-4. "I think it was just overwhelming,” Gauff told reporters afterwards. “Obviously, I'm losing the match.

"When you're playing against her every point matters... against anybody, but especially against her. I think it was just one of those moments, but I overcame it. I won that game.

"I usually don't get too frustrated with decisions like that, but I think it was just a combination of everything going on in the moment."

The French Open is unique in that it does not use technology to assist the umpire's decisions, with even hawk eye snubbed in favour of checking the clay for ball markings. There is also no Video Review (VR) system due to the desire to stick with tradition and a reluctance to cede human control.

Swiatek, who claimed a third straight Roland Garros title by defeating Jasmine Paolini in the final, admitted having replays would be "easier". She said: "I think it would be easier to have the replay, but I don't know how it would look logistically.

"When can you ask an umpire to call a video replay or when is it up to her to do that. Because I think the umpire today was pretty sure with her call.”

Meanwhile, a frustrated Gauff vented: "I think tennis is the only sport where not only we don't have the VR system, but a lot of times the decisions are made by one person.

"I know the US Open brought some of it last year. I know we used it in our doubles at one point. I definitely think it's almost ridiculous we don't have it. Not just speaking because that happened to me, but I just think every sport has it."

She is not the first player to call for technology to help officials. Briton Cameron Norrie claimed video replays should be used after he got away with a double bounce during his second round victory over Lucas Pouille at Roland Garros last year.

The US Open became the first Grand Slam to use the system at last year's tournament. That was not without controversy, however, as British tennis legend Andy Murray called the new system a “farce”.

An umpire pulled out a tablet to watch an instant replay of an incident during Murray’s first-round match in New York against Corentin Moutet. Serving for victory, the umpire requested the technology to check a double bounce which was called against the Scotsman.

After a lengthy delay, the official announced the VR was “not working”, sparking the wrath of Murrary. Video review technology has since mostly garnered positive feedback at the various ATP events where it has been used.
