Gauff calls for video replays after controversial decision during semi-final loss

The American third seed missed a return on Swiatek's serve at 2-1 up in the second set as a line judge called out, but the decision was reversed by the chair umpire who disagreed with the American's argument that her shot was affected in the process.

Gauff, who was booed by the Philippe Chatrier crowd, wiped away tears at the baseline before regrouping to break Swiatek, but she could not stop the top seed from clinching a 6-2, 6-4 win.

"I think it was just overwhelming. Obviously, I'm losing the match," Gauff told reporters.

"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.

"So 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."

Gauff is not the first player to call for technology to help officials, as Briton Cameron Norrie said video replays should be in use 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 with video reviews generating positive feedback at the various ATP events at which it is used.

"Tennis is the only sport where not only we don't have the VR system, but a lot of times decisions are made by one person. In other sports there are usually multiple referees making a decision," Gauff said.

"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.

"Also, there are so many decisions that are made, and it sucks as a player to go back or online and you see that you were completely right, and it's, like, what does that give you in that moment?

"In situations you can call for the supervisor, but there's not much they can do from that standpoint. I definitely think as a sport we have to evolve, and we have the technology. They're showing it on TV, so I don't get why the player can't see it."

Swiatek said there would be other challenges associated with replays.

"Honestly, I don't know how it would look logistically," the Polish player said. "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.

"So I don't know how that would look like."
