Naomi Osaka of Japan has won US Open after defeating Serena Williams of the United States. 
Osaka became the first Japanese woman to win a Grand Slam title as her idol Serena Williams imploded in the face of a code violation from the chair umpire on Saturday.
Osaka, 20, triumphed 6-2, 6-4 in the match marred by Williams’s second set outburst, the American enraged by umpire Carlos Ramos’s warning for receiving coaching from her box.
She tearfully accused him of being a “thief” and demanded an apology from the official.
Serena Williams’ bid for a 24th Grand Slam title imploded in a furious tirade against umpire Carlos Ramos, calling him a thief after he docked her a point for two code violations.
Her outburst then earned her a game penalty, prompting a further outburst to tournament officials and putting Naomi Osaka within one game of victory.
