Naomi Osaka, winner of the Australian Open, has jumped to the top of women’s tennis with her beaten opponent Petra Kvitova rising to second in Monday’s WTA rankings.
Osaka, born and raised in Japan, is of Haitian heritage by way of her father.
Osaka climbed three places after beating the Czech in Melbourne on Saturday. Kvitova moved up four places.
The 21-year-old Japanese player has only won three career titles, but those include the last two majors, after she won the US Open in September.
