Naomi Osaka vowed to continue highlighting issues of racial injustice after reaching the second round of the US Open with a hard-fought win over Japanese compatriot Misaki Doi.
Osaka, who initially pulled out of her semi-final at last week's Western & Southern Open in solidarity with protesters, wore a face-mask onto the court bearing the name of
Breonna Taylor, who was shot dead by police in Louisville in March.
The 22-year-old Osaka said after her 6-2, 5-7, 6-2 win that
she planned to wear a mask bearing the name of a different shooting victim for each round that she remains in this year's tournament.
