Tennis superstar Naomi Osaka wore a Breonna Taylor tribute mask to her 1st round match at the U.S. Open on Monday ... and says she's got more tributes planned.
The 22-year-old has been very outspoken about social justice issues lately -- and even "boycotted" a match at a different tournament last week in the wake of the Jacob Blake shooting.
So, when she arrived at the USTA Billie Jean King National Tennis Center in New York City, she rocked the Breonna mask to help "spread awareness" about the Taylor case.
"I'm aware that tennis is watched all over the world, and maybe there is someone that doesn't know Breonna Taylor's story," Osaka said.
