Martina Navratilova won nine Wimbledon singles titles 
 
 Martina Navratilova says she would not be surprised if female players boycotted Indian Wells as a result of the row ignited by the tournament's chief executive. 
 
 Raymond Moore said the women's game "rides on the coat-tails" of the men and that Roger Federer and Rafa Nadal have "carried this sport". 
 
 Moore, 69, has since apologised. 
 
 But Navratilova, an 18-time Grand Slam winner, says women may not want to play at Indian Wells if he stays in charge.

 The 59-year said the views of South African Moore were "really disheartening", "extremely prejudiced" and "very old-fashioned".

 "We have made it this far on our own, without help from male players, and will continue to do so in the future," Navratilova added. 
 
 "It would be hard to imagine any women to want to go and play at Indian Wells if Moore stays as the tournament director." 
 
 Navratilova was also disappointed by comments from world number one Novak Djokovic, who said he believes men should be awarded more prize money than women because it was more popular. 
 
 Speaking after his straight-sets win over Milos Raonic in the men's final at Indian Wells, the Serb said women deserve the money they get, but men should fight for more because their game attracts more viewers. 
 
 "Novak Djokovic, as much as I love him, clearly doesn't understand why, when women and men play in combined tournaments, they must be paid equally," Navratilova said. "I thought we settled that issue years ago." 
 
 World number one Serena Williams said Moore's statement was "offensive", calling it "mistaken and very, very, very inaccurate".

 There has been equal prize money in all four majors - the Australian Open, US Open, French Open and Wimbledon - since 2007, as well as at combined Masters events, such as Indian Wells and Miami. 
 
 But female players are paid significantly less at women-only events when compared with similar-sized men's tournaments. 
 
 Who else has spoken out? 
 
 The United States Tennis Association (USTA) said player equality is a "bedrock" principle and has been extremely critical of Moore. 
 
 "There is no place in this sport for antiquated, sexist or uninformed ideologies," read a statement from Katrina Adams, who is the USTA's chairman, chief executive and president. 
 
 She added that Moore's remarks "in no way reflect the beliefs of the vast majority of those in the tennis world". 
 
 Chris Kermode, chief executive of the Association of Tennis Professionals, called Moore's comments "disparaging" and said they had been "made in poor taste". 
 
 Former British Davis Cup captain David Lloyd backed Djokovic's assertion that the men's game was more popular than the women's right now but said the opposite had been true in the past. 
 
 Lloyd said the women's game had been "better" to watch than the men's when Steffi Graf and Monica Seles were at their peak in the early 1990s. As a result, the public had been willing to pay more to see them play. 
 
 "It's supply and demand and it could swing back in the future," he said. 

 Indian Wells CEO Raymond Moore says women players ride the coattails of the men and don't make any decisions, and if he were a "lady player," he'd thank God that Roger Federer and Rafael Nadal were born because those men have carried the sport. (1:02) 
 
 Raymond Moore has resigned as CEO and tournament director at Indian Wells, owner Larry Ellison announced Monday night. 
 
 Moore's resignation came one day after he said women players ride the coattails of the men. He later apologized, but his remarks drew widespread outrage. 
 
 "I think the WTA [Women's Tennis Association] ... you know, in my next life, when I come back, I want to be someone in the WTA because they ride on the coattails of the men," Moore said Sunday before Serena Williams faced Victoria Azarenka in the final of the BNP Paribas Open. "They don't make any decisions, and they are lucky. They are very, very lucky. If I was a lady player, I'd go down every night on my knees and thank God that Roger Federer and Rafa Nadal were born because they have carried this sport. They really have." 
 
 Moore, 69, is a former professional player from South Africa. He was involved with the tournament at Indian Wells for 29 years as an owner and managing partner before he assumed his most recent post overseeing tournament operations and the Indian Wells Tennis Garden in 2012. Years ago, Moore and another former player, Charlie Pasarell, started PM Sports Management, which oversaw the tournament as it expanded. 
 
 "Ray let me know that he has decided to step down from his roles as CEO and Tournament Director, effective immediately," Ellison said in a statement Monday night. "I fully understand his decision."

 Ellison noted the "ongoing, multi-generational, progressive movement to treat women and men in sports equally" and that women and men have been paid equal prize money at all major tennis tournaments, including Indian Wells, for a decade. 
 
 "Thanks to the leadership of Billie Jean [King], Martina Navratilova, Venus Williams, Serena Williams and so many other great women athletes, an important measure of success has already been achieved," he said. "All of us here at the BNP Paribas Open promise to continue working with everyone to make tennis a better sport for everybody." 
 
 WTA CEO Steve Simon issued a statement Tuesday morning on Moore's resignation, saying "it is the right decision." 
 
 "Raymond Moore has taken full responsibility for the unacceptable comments he has made," Simon said. "It is the right decision for him to step down. The BNP Paribas Open has supported the payment of equal prize money to all players since 2009. The WTA looks forward to working with Mr. Ellison and the Indian Wells team on continued efforts in making the sport better and equal for all players." 
 
 Moore complimented Serena Williams on Sunday while talking about the state of women's tennis. He said Williams is "arguably the best female player of all time." However, he also said, "I think the WTA have a handful -- not just one or two -- but they have a handful of very attractive prospects that can assume the mantle. You know, [Garbine Muguruza], Genie Bouchard. They have a lot of very attractive players. And the standard in ladies' tennis has improved unbelievably." 
 
 Asked to clarify whether he was talking about physical attractiveness or competitive attractiveness, Moore responded, "I mean both. They are physically attractive and competitively attractive. They can assume the mantle of leadership once Serena decides to stop. I think they've got ... they really have quite a few very, very attractive players." 
 
 Moore later apologized in a written statement. 
 
 "At my morning breakfast with the media, I made comments about the WTA that were in extremely poor taste and erroneous," he said. "I am truly sorry for those remarks and apologize to all the players and WTA as a whole. We had a women's final today that reflects the strength of the players, especially Serena and Victoria, and the entire WTA. Again, I am truly sorry for my remarks." 
 
 Williams was among the many who fired back at Moore. She was asked about Moore's comments after she lost to Azarenka in the final. 
 
 "Obviously, I don't think any woman should be down on their knees thanking anybody like that," she said. "I think Venus, myself, a number of players have been -- if I could tell you every day how many people say they don't watch tennis unless they're watching myself or my sister, I couldn't even bring up that number. So I don't think that is a very accurate statement. I think there is a lot of women out there who are more ... are very exciting to watch. I think there are a lot of men out there who are exciting to watch. I think it definitely goes both ways. I think those remarks are very much mistaken and very, very, very inaccurate." 
 
 Williams said she was surprised to hear sexist remarks such as Moore's these days. 
 
 "Yeah, I'm still surprised, especially with me and Venus and all the other women on the tour that's done well," she said. "Last year, the women's final at the US Open sold out well before the men. I'm sorry, did Roger play in that final or Rafa or any man play in that final that was sold out before the men's final? I think not." 
 
 Before the backlash over Moore's controversial comments began, he was asked Sunday how long he planned to remain in charge at Indian Wells. 
 
 "Firstly, I love what I'm doing. I'm passionate about it. I enjoy it," he said. "Who knows who the face of the tournament will be down the road. But I don't think that, oh, I'm going to stop next year or three years." 
 
 Information from ESPN's Jim Caple and The Associated Press was used in this report.
– On Sunday he was riding high as CEO of California's Indian Wells Tennis Garden and director of the BNP Paribas Open tournament held there. On Monday, Raymond Moore stepped down from both posts, reports the New York Times, after making disparaging comments about women tennis players over the weekend, including saying that women "ride the coattails of the men" players and that they should get down on their knees to thank top male players for keeping the sport going. Oracle founder Larry Ellison, who owns the tourney, said Moore had informed him of his resignation and that "I fully understand his decision." The 69-year-old Moore had offered up mea culpas, but pushback from the tennis community, including Serena Williams and the CEO of the Women's Tennis Association, soon took over. Ellison pointed out the "ongoing, multi-generational, progressive movement to treat women and men in sports equally," ESPN reports, and cited female tennis greats such as Billie Jean King, the Williams sisters, and Martina Navratilova, who per the BBC called Moore's comments "really disheartening" and "extremely prejudiced." "We have made it this far on our own, without help from male players, and will continue to do so in the future," she said, noting how she didn't see how women could continue to play at Indian Wells if Moore stayed.
