Ahead of the Western & Southern Open, Tsitsipas did his own Instagram Q&A and he was asked about Osaka. He said the world No. 10 is an introvert trying to be an extrovert and has the scariest forehand.
Osaka had a response for him.
"I saw one where he said I was an introvert or something," she said in press. "It was kind of rude. I’m trying my best."
She followed up with a lighthearted threat.
"I would tell him to watch out because I have a lot of stories about what he did when I first filmed him in the suite next to me," she said.
Fans would certainly love to see what content she's collected.
"But no, I guess I would say we’re kind of the same so I know where he’s coming from because I do try to be outgoing sometimes," Osaka added. "For me, I feel that’s something I’m getting more comfortable with . So yeah we’re similar."
When Osaka boycotted play last week, making headlines and raising awareness, Tsitsipas wasn't paying close attention but he did reach out to her.
"I wasn't following, really. I was playing my match," he told press. "But really good for her. I'm happy for her. She's in a good streak, a good run. She's playing well. She's playing well, definitely. Honestly, I don't really watch much woman's tennis, but I admire her a lot."
Both have been playing well in New York with Osaka reaching the final at the Western & Southern Open, and winning her US Open first round over Misaki Doi. Tsitsipas would make the semifinals and then dismissed Albert Ramos Vinolas in his first match this week.
They'll be night matches on Wednesday with Osaka taking on Camila Giorgi and Tsitsipas facing Maxime Cressy.
