Former British ATP player Andrew Castle has voiced his concerns regarding the recent changes to the US Open's mixed doubles format. He argues that the revamp has significantly impacted specialist doubles players, potentially jeopardizing their careers. Castle expressed disappointment over the direction the tournament has taken, suggesting that the changes may not be in the best interest of those who primarily compete in doubles. The mixed doubles event has gained popularity, attracting high-profile players, but Castle believes that the new format could lead to unintended consequences for dedicated doubles specialists. As the US Open approaches, this critique adds to the ongoing discussions about the evolution of the tournament and its implications for players across different disciplines.
