Kyrgios fired back: "Well, you’ll never have her."
Who's saying what
"She hit a second serve, right? And in my mind, right before she hits the second serve, I'm thinking, Do not hit this down the line. Don't go for it, right? And then there is another part of me that's, like, But if I hit this down the line, there is a 50/50 chance it will be a winner and you could win the point easy. And then when she's serving the ball, it's like ta, ta, ta, ta, ta, and I'm arguing with myself. Do it, don't do it, do it, don't do it. And then the ball comes and I hit it down the line and it goes in the net. I'm, like, Why did I do that?"
