Emma Raducanu won the clash of Grand Slam champions, ousting Naomi Osaka at the 2025 Citi Open. She was in complete control of the second-round encounter, coming through in straight sets.
The 2021 US Open champion has been struggling with injuries and a loss of form, but looked at her vintage best when taking the ball early in her match against Osaka.
The Japanese player has four Grand Slam titles to her name, all of which came on the hardcourts. Raducanu was aware of the threat that her opponent posed and was, in fact, proud of how she handled the match.
The Briton showered praise on Osaka during her on-court interview, saying she knew that she would need to be at her best to beat her fellow Slam champion.
“I felt it was going to be a really difficult match. Naomi’s won four Slams, been No. 1, won Masters, she’s so dangerous," Emma Raducanu said. "On hard courts she’s particularly comfortable. I knew I was gonna have to play really well."
Dissecting the match-up further, Raducanu said that the key for her was to serve well. By getting through her service games quickly, she said, she was able to focus on making inroads into Osaka’s service game. She successfully broke her opponent on three occasions.
"I knew I was going to have to manage my own service games, which I'm really proud of how I did," Raducanu said. "Then I was making inroads into her service games once I got used to it a bit ... If you float the second serve in, Naomi's going to crunch it. I had to trust my abilities in the second serve and go for it."
Emma Raducanu continues strong run at Citi Open with Naomi Osaka win

Emma Raducanu has found her footing after enduring an up-and-down start to the 2025 season. Before beating Naomi Osaka at the Citi Open, she had also posted a solid win over seventh seed Marta Kostyuk.
The Briton’s fortune had, in fact, turned around at the start of the grass swing. She made a strong start by making the quarterfinal at the Queen’s Club Championships before following it up with decent showings at Eastbourne and Wimbledon.
At the Wimbledon tournament, Raducanu beat former champion Marketa Vondrousova and Mingge Xu before putting up a brave fight against World No. 1 Aryna Sabalenka.
