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."AdvertisementAdvertisementAdvertisementCirstea, 35, announced last month that she would retire at the end of the 2026 season after 20 years on the WTA Tour. Osaka said her outfit was originally inspired by a jellyfish which she saw in a book while reading to her two-year-old daughter []Osaka arrived on court in a toned-down version of her jellyfish-inspired outfit that stunned spectators on Tuesday. She chose not to wear the white hat and veil again and also arrived without the white umbrella - but that did not stop some fans in the stands trying to imitate the already-iconic look."This is just something fun that I like to do on the court," Osaka said of her outfit."I don't really talk that much, but I like to express myself through clothes and I'm really glad that you guys loved it."AdvertisementAdvertisementAdvertisementOsaka is hoping to reach the fourth round of the Australian Open for the first time since she won the tournament in 2021. The two-time Melbourne champion will face Australian qualifier Maddison Inglis in the third round after the world number 168 beat Germany's Laura Siegemund. Elsewhere on Thursday, defending champion Madison Keys claimed a 6-1 7-5 win over fellow American Ashlyn Krueger, while American sixth seed Jessica Pegula required just 58 minutes to beat her doubles partner McCartney Kessler 6-0 6-2. Second seed Iga Swiatek continued her bid to make history and complete the career Grand Slam with a comfortable 6-2 6-3 win over Czech Marie Bouzkova.
