World number one Novak Djokovic said he never meant to cause controversy by saying male players deserve more prize money than women.
The 11-time Grand Slam champion said he spoke out because the sport needed a "fairer and better distribution of funds across the board".
He added he cares "deeply" about tennis and that his remarks were "not the best articulation of my view".
He apologised to anyone who had taken his comments "the wrong way".
Djokovic's remarks had drawn criticism from high-profile players Serena Williams and Andy Murray.
Williams, the women's number one, said the Serb was "entitled to his opinion" but wondered what he would say to his daughter if he had one.
