Grand Slam champions Coco Gauff and Aryna Sabalenka admit they support video review technology across all tournaments.
In the second set of her Olympic defeat against Donna Vekić last month, the match was overshadowed by a close line call decision, with the American pointing to the ball mark and was heard saying to the umpire who shouted "correction" during Gauff's swing, "you have to understand this is not fair," before continuing the argument for several minutes.
There was also controversy last week between Jack Draper and Felix Auger-Aliassime at the Cincinnati Masters, with replays confirming Draper had hit the ball into his side of the net and subsequently sealed progression on match point.
Gauff, a massive advocate for technology implementation to erase avoidable errors, doubled down on her take.
"We're playing for too much on the line for that not to be a thing, especially when other sports have it where maybe they don't even have as much of the resources tennis has financially," the reigning US Open champion said during her pre-tournament press conference.
"I definitely think that it should be, especially at the slams, it should be here and 1000 tournaments. Obviously I would like to see it across all levels, but I definitely would love to see it at the highest of levels first. US Open had it last year. I didn't have to use it. Hopefully, I won't have to use it this year, but I think it's a great thing.
"The worst is when you get apologised to afterwards, and it's kind of just like, thanks, but, what is that going to do for me now? I think it'll just hold everybody accountable. There will be a lot less player frustration and outbursts with that.
"I'm excited. I hope to see it continue to expand not just in this tournament but all tournaments. I think the fans would appreciate it too because I think there's nothing more frustrating for a fan to go and see that happen to their player and you're seeing that your player is right or wrong, and the player itself doesn't know."
Former world No.1 Aryna Sabalenka shared her rival's viewpoint on the issue.
"I think that's really important that we have this system here because I saw those tough calls," Sabalenka said.
"I think that's really unfair for some of the players not to be able to review the referee calls. And also, for the referees, you kind of can understand. Tennis [has] improved a lot, and it's faster, it's not that easy to be a chair umpire.
"That's going to be helpful for everybody and healthy for everyone to have these reviews, so I think that's really a cool thing to have.”
Eight courts at the US Open will have a video review system in place for non-line calls.
