Naomi Osaka said she would be willing to undergo two more weeks of quarantine to play at the Tokyo Olympics later this year, if it helped ensure the safety of the people of her home country.

Two days after completing 14 days of isolation in Adelaide ahead of the Australian Open, the U.S. Open champion said she would be prepared to do it all again to play in the Olympics on home soil.

"The way that I feel is I will stay in my room for two weeks to play the Olympics," the 23-year-old told reporters on Sunday.
