2018 US Open Women's Singles Final - Japan's Naomi Osaka beat USA's Serena Williams,became the first Japanese to win a Grand Slam singles title Saturday Sep 08,2018

Naomi Osaka became the first Japanese to win a Grand Slam singles title on Saturday Sep 08,2018 as her idol Serena Williams angrily imploded, calling the chair umpire in the US Open final "a thief".

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.

Naomi Osaka had not even celebrated her second birthday when Serena Williams had won her first title at US Open. Now with Osaka a 20-year-old, training in Florida having come to New York at 3-years-old, she beat her much senior opponent to win the US Open title on Saturday. By winning 6-2, 6-4 at Flushing Meadows, Osaka became the first Japanese player – man or woman – to win a grand slam title. She had already become the first Japanese woman to make the final of a grand slam by booking a ticket for the high-profile showdown on Arthur Ashe Stadium.
