The players have sent a letter to the organisers of the Australian Open, French Open, Wimbledon and the US Open asking for a meeting about the distribution of the revenue generated by the four major events.

World number 11 Emma Navarro has revealed that she signed the letter in protest at "unfair pay ratios".

The American player said: "I talked a little bit to the other players about it and felt like it was a good idea to sign.

"I think it's a good cause to come together as players and make sure we're getting treated fairly."

In 2024, a record $254 million in player compensation was awarded at the Grand Slams - an increase of $23 million on the previous year - but players continue to protest at how they believe they should be earning a greater amount of the cash generated.

Olympic champion Qinwen Zheng believes that the proposed changes will be particularly beneficial for the lower-ranked players.

The world number eight said: "I think that's going to benefit all the players, not only the top players, especially those that work hard during the year and need to get paid from the Grand Slams and have to survive."

Zheng pointed to the example of the NBA's model as players earn around 50 per cent of basketball-related income.

The Chinese player said: "If you look at basketball, they all get paid 50-50.

"The players, we’re working really hard, because I’m a tennis player I know how much I’ve worked to arrive here.

"We try to do what we can, and then let's see what the gods bring to us. But at least we're trying."
