Champion Osaka harnesses sport's biggest spotlight in fight for racial justice
Naomi Osaka capped a transformative US Open with another Grand Slam title and a challenge to the millions watching across the globe on Saturday to "start talking" about racial justice.
Striding into Arthur Ashe Stadium for her first-round match 12 days ago, Osaka put her activism front-and-center from the start, wearing a mask to honor Breonna Taylor, a Black woman killed by police officers who burst into her apartment in March.
