Through her words and deeds of recent months, both on and off the court, Naomi Osaka has shown that she could be the leading figure women's tennis has been waiting for.
Her third Grand Slam title, achieved at the US Open on Saturday night with a stirring comeback against Victoria Azarenka, suggested that she is a champion who could become the first female serial winner of Majors since Serena Williams.
More than that, her now well-documented campaigning on social justice issues demonstrated that she is a person unafraid to back away from standing up for principles that are important to her.
