Russian tennis player Daria Kasatkina has announced she is gay and has a partner. Kasatkina is Russia's top-ranked player and the world No.12. In a video interview with a blogger, she also criticised the fact there are so many "taboo topics" in Russia. "For young people facing problems in public, it is very important when athletes or other well-known personalities talk about it," she said. Same-sex relationship are generally frowned upon in Russia. Kasatkina praised Russian footballer Nadezhda Karpova for opening the door after becoming the first female Russian sportswoman to come out in June. There had been movement toward more openness at the 2018 football World Cup in Russia, Kasatkina said, but no longer as Russia closes ranks following the invasion of Ukraine. "The way was closed. Road works," Kasatkina said. The 25-year-old has won four WTA titles. Australian Associated Press
