The first one will be played between Sabalenka and Osaka and the second one will pit Kyrgios against Shelton.Nick Kyrgios and Aryna Sabalenka show readiness for Battle of Sexes encounterNick Kyrgios is already feeling the pressure as he said he will be representing men's tennis in the Battle of Sexes showdown. In a recent interview with the Australian Associated Press, Kyrgios talked about the outside noise and the support he has received from other male players."I was in Hong Kong recently and a lot of the male players were like, ‘Look, you're representing all of us.' So here I am in the firing line again," Kyrgios said. "I'm not a stranger to taking the heat from the media, but I'm excited whatever the result may be."I'm going to go out there and show the world that as good as she is, she's got some weaknesses."The Australian will have some rules working against him for this match. This includes having only one serve and putting the ball in play on Sabalenka's smaller court. The rules are bent to make the one-set match competitive, which Kyrgios predicts he will win by "6-2."“She [Sabalenka] is not gonna beat me," Kyrgios said via Tennis 365. "Do you really think I have to try 100 per cent? I’m going to try. Because I’m representing the men’s side. I’d say like 6-2 maybe. I’m not going to go there and say, ‘Oh, she’s so good, I can’t play this.’ That would make me look so bad. I’d imagine the internet would go crazy -- go bananas.“I mean, our serves, women can’t really return those. And then we can just chip and drop shot. You [Bublik] can drop shot, they would have no idea. I think I’m going to be okay. I’m going to go there, and I don’t want her to win. That’s for sure.”Meanwhile, Sabalenka herself is prepared to "kick his (Kyrgios) a**."
