Players, legends and national federations have signed an open letter opposing ATP proposals that would shrink doubles draws and halve the prize-money share from 2028, with the board due to vote at the ATP Finals in Turin.

More than 150 men's doubles players, joined by tennis legends and more than 20 national federations, have signed an open letter asking the ATP to reconsider reforms they say threaten the future of the discipline. Signatories include Britain's Henry Patten, who is world number one with Finland's Harri Heliovaara, and the Bryan brothers. According to BBC Sport and the Guardian, the proposals would halve doubles draws from 2028, leaving 16 teams at Masters 1000 events and eight in the main draws at ATP 500 and 250 tournaments, and cut the share of prize money going to doubles from 20% to 10%, with the difference redistributed to singles.

In the letter, the players say the plans would move about $20m (£15m) from doubles to singles and remove many professional opportunities, making it far harder for talented players to build a doubles career. Sem Verbeek, the 2025 Wimbledon mixed doubles champion and one of the campaign's organisers, told the Guardian and BBC Sport that the proposals would destroy careers and that the ATP had not answered the players' requests for data or genuine collaboration. The Bryan brothers said they would back legal action, recalling the players' 2005 lawsuit against the ATP over doubles changes. The ATP says its review is data-led, aimed at a more sustainable model for tournaments and fans, and its chief executive Andrea Gaudenzi has written that doubles will remain a core part of the tour.

The ATP board, made up of chairman Gaudenzi, four tournament representatives and four player representatives, is due to vote on the plans at the ATP Finals in Turin in November, as part of a wider review meant to strengthen the tour from 2028. Some figures in the sport accept that reform is needed, arguing that a 20% prize-money share is out of proportion to fan interest, while the players counter that the ATP has under-marketed doubles. The players say they see little appetite for negotiation, but ATP sources told BBC Sport they expect a compromise to be found.
