Third-seeded Japan's Naomi Osaka advanced to the third round of the US Open as her opponent Olga Danilovic withdrew due to illness.

Said Serbian qualifier Danilovic on Instagram, "I have been feeling unwell these past few days dealing with a non-COVID-related viral illness."

"I am so sad to have to withdraw from my match this morning. I was really looking forward to playing against Naomi on Arthur Ashe Stadium today, but not to be this time." the 20-year-old added.

Osaka will now face Canada's 73rd-ranked Leylah Fernandez.
