Naomi Osaka has apologised for “disrespecting” Sorana Cirstea in her post-match on-court interview after she received a frosty handshake and a telling-off from the Romanian.

After wrapping up a 6-3 4-6 6-2 win against Cirstea in the Australian Open second round, a smiling Osaka made her way to the net to carry out the post-match formalities.

But Cirstea gave a brief handshake before exchanging some words with the Japanese 16th seed by the umpire’s chair.

Asked in her on-court interview what it took to get past Cirstea, Osaka said: “Apparently a lot of ‘come ons’ that she was angry about.”

The interviewer then asked if Cirstea was complaining because she could hear Osaka trying to pump herself up between the Romanian’s first and second serves.

“I think so, but like, she could have asked me. I’m sorry,” former world number one Osaka replied.

“She’s a great player. I think this was her last Australian Open, so sorry she was mad about it.”

In a later news conference, Osaka apologised for some of her post-match comments towards Cirstea, who is retiring from tennis at the end of the 2026 season after 20 years on the WTA Tour.

“I’m a little confused. I guess that emotions were very high for her. I also want to apologise,” the four-time major winner said.

“I think the first couple of things that I said on the court were disrespectful. I don’t like disrespecting people. That’s not what I do.”

However, Cirstea said there was “no drama” between herself and Osaka.

“It was just a five-second exchange between two players that have been on a tour for a long time. It stays between us,” Cirstea, 35, said.

“Look, this is my last Australian Open. I have been playing for 20 years. It’s more going on than a five-second discussion at the end that I had with Naomi.”
