Alignment of the ATP and WTA has been discussed on and off for years but might be closer than ever following Federer — arguably the most popular player in tennis history — asking on April 22, "Just wondering…am I the only one thinking that now is the time for men's and women's tennis to be united and come together as one?"Follow @cnnsport The men's record 20-time grand slam winner immediately got support from friend and 19-time major champion Rafael Nadal, with Murray — another member of tennis' Big Four — now joining them. Murray has long been a champion for equality, becoming the first high-profile male player, for instance, to employ a women's coach. "I think it's great if more of the male players are seeing it as a positive step for the sport," Murray told CNN's Christiane Amanpour as she interviewed the three-time grand slam winner and trailblazer Billie Jean King. "I think we have a very unique sport in that we have the men and the women competing at the biggest competitions together. That doesn't really happen in any of the other global sports and I see that as a big positive. We have equal prize money at the events which I think is fantastic and very attractive to sponsors, to the audience. "We have pretty much a 50/50 kind of audience split between men and women which again is rare across sports and I think all of these things are things that we should be celebrating in the sport. "Sometimes they aren't and there's a lot of in-fighting that goes on with these things and I don't think that should be the case. There's obviously going to be some issues potentially with a merger, as well, but it is definitely I think a step in the right direction to start these conversations."It was King who sought to come together with the men nearly 50 years ago, which Murray was quick to point out. But when the men declined, King founded the WTA tour. She was "thrilled" with Federer's public declaration because "when top male players bring it up, people listen." The 76-year-old American has spoken with the Swiss, who is part of the ATP's player council alongside Nadal and, among others, the other Big Four member, Novak Djokovic. The lone prominent player to publicly go against the idea has been Murray's friend, the sometimes controversial Nick Kyrgios.
"We can grow," said King. "But what we have to understand is we have to stay together as a sport, because we're not competing within our sport like a lot of tennis people think. We need to compete against the other entertainment and other sports. "I don't think people realize we are in this business. And so I think it's very important that we are together, that we're not an acquisition. The WTA would not be an acquisition. We would be a full partner in this drive to make our sport better and more valuable. "Can you imagine how strong we could be if we negotiate as one voice? Ka-ching."Indeed, a combined tour would presumably strengthen the bargaining position of players at a time when they are seeking a larger piece of tennis' revenue, particularly for lower-ranked players and at grand slams. The current suspension of the tours due to the virus has given the ATP and WTA more time to discuss matters than ever before, while new ATP chairman Andrea Gaudenzi seems intent on collaborating with the WTA. "Recent cooperation between governing bodies has only strengthened my belief that a unified sport is the surest way to maximize our potential and to deliver an optimal experience for fans on-site, on television and online," Gaudenzi said in a statement sent to CNN last month. He stopped short at this stage, though, of calling for a formal merger. WTA chairman and CEO Steve Simon added in a statement: "I have long stated that we are at our best as a sport when we can work together, and the recent weeks have highlighted that fact."He has always been a fan, for example, of mixedRead More – Source
