Tennis star Jannik Sinner has criticized grand slam tournaments for neglecting discussions about prize money and welfare benefits for lower-ranked players. Proposals from the top 10 male and female players to alter prize money were rejected by the grand slams in August, and a request for a meeting during the US Open was also denied. Sinner argues that there is no valid reason for the grand slams’ inaction on these issues, which are crucial for the welfare of players.
