Naomi Osaka becomes highest-paid female athlete of all time

Japanese tennis star Naomi Osaka, 22, has become the highest-paid female athlete in history after raking in $37.4 million last year, Forbes reports.

Why it matters: Pay disparities for women in professional sports have drawn attention in recent years, especially after U.S. women's national soccer team accused the U.S. Soccer Federation of "institutionalized gender discrimination" in 2019. Professional female athletes also told "Axios on HBO" in March that the fight for equal pay has a long way to go.
