Novak Djokovic's calls for better financial rewards for lower-ranked men's tennis players have been answered after it emerged a new minimum wage will be offered to those struggling to keep afloat. The Serbian has been a strong advocate for financial aid to be provided to players for whom the costs of travelling around the world are more significant due to the lower prize money won for lower-profile tournaments.
Plans have been put in place to ensure that male tennis professionals are not left out of pocket when travelling to play in tournaments, with a guarantee of a fixed amount to cover the top 300 players based on their estimated earnings for the season.
