Naomi Osaka pokes fun at Japan comedians' 'bleach' comments

Naomi Osaka poked fun on Sunday at a Japanese comedy duo's reported comments that the Japanese and Haitian tennis star needed to pick up some "bleach."

The relatively unknown female comedy pairing "A Masso" reportedly suggested last week Osaka needed "bleach," and said the 21-year-old former world number one was "too sunburned" during a live performance.
