Naomi Osaka Is the 1st Haitian-Japanese to win the US Open.

Naomi Osaka was a few months old when Serena Williams won her first major title. Playing her 31st career Grand Slam final, Williams couldn't overcome a controversial umpire call to defeat her 20-year-old rival.

In a dramatic — but short — women's final on Saturday night, 20-year-old Naomi Osaka from Japan won her first Grand Slam title against her idol Serena Williams 6-2, 6-4 in an hour and half. She is the first player from her country to win a Grand Slam title.
