Organisers of the US Open tennis championship last year sold more than 500,000 of their signature cocktail, “Honey Deuce”. At $23 per glass, the drink grossed $13mn. By contrast, the men’s and women’s champions of the New York City event took home combined prize money of just $7mn.

The tennis world was surprised when Novak Djokovic voiced his opposition to several aspects of the lawsuit the Professional Tennis Players’ Association (PTPA) brought against top government bodies of the game.

Novak Djokovic doesn’t want the antitrust lawsuit filed by the players’ association he co-founded to create a rift in tennis, but he also said Thursday that the athletes’ share of revenues and their influence both need to increase.
