Naomi Osaka, the four-time Grand Slam champion, has dropped out of the top five in the latest WTA Rankings.
After losing her third-round match at the 2021 US Open, the Japanese star dropped from fifth to eighth place.
Former world number one Simona Halep, for example, fell to 14th place.
Meanwhile, the top-ranked player is Ashleigh Barty.
Osaka has decided to retire from tennis indefinitely
Leylah Fernandez, a Canadian teenager, stunned Osaka in the third round of the US Open. Osaka was defeated 5-7, 7-6(2), 6-4 by the latter.
Shortly after, Osaka announced that she will be taking a break from tennis indefinitely.
“I don’t know when I’m going to play my next tennis match. I think I’m going to take a break from playing for a while,” Osaka said.
Osaka is currently 18-6 on the season
Osaka lost in the third round of the Cincinnati Open to Swiss wildcard Jil Teichmann before the US Open.
Prior to that, Osaka was eliminated in the third round of the Tokyo Olympics.
She withdrew from her first-round match at Roland Garros and did not compete in the rest of Wimbledon.
After winning the Australian Open, the Japanese haven’t been at her best.
In the current season, she is 18-6.
Osaka attained this feat after winning the Australian Open
Osaka had defeated 22nd seed Jennifer Brady to win her second Australian Open title earlier this year. She is only the third player in the Open Era to win her first four Grand Slam finals after Roger Federer and Monica Seles.
Barbora Krejcikova rises to career-high fifth spot
Along with Osaka, Halep also slipped in the WTA Rankings.
The latter lost her last 16 clash to Elina Svitolina at the US Open.
Meanwhile, French Open winner Barbora Krejcikova attained her career-best ranking of number five.
World number one Barty retains her spot even though she lost in the third round in New York.
She had previously won Wimbledon and the Cincinnati Open.
