Naomi Osaka drops out of WTA top ten
Naomi Osaka has dropped out of the women's top 10 for the first time since winning the 2018 US Open title.
The Japanese superstar is now ranked 12th in the world after what has been a turbulent period for her. Osaka was in the news for several reasons after she withdrew from this year's French Open and missed Wimbledon to focus on her mental health.
The 23-year-old was knocked out of the Olympics and took a break from tennis in September after her defence of the US Open title was ended by Leylah Fernandez in the third round. Great Britain's Emma Raducanu, who beat Fernandez in the final, is ranked 22nd.
Former world number one Osaka, a four-time Grand Slam winner, recently said she will return to tennis soon after getting the "itch" to play again.
