Naomi Osaka is into the third round of the Tokyo tennis tournament.
The host country’s superstar stepped up her game when she needed to in a 6-3, 6-2 win over 49th-ranked Viktorija Golubic of Switzerland to reach the last 16 at Ariake Tennis Park.
The second-ranked Osaka will next face either 2019 French Open runner-up Marketa Vondrousova of the Czech Republic or Mihaela Buzarnescu of Romania.
