Paris: Naomi Osaka's win over world number one Ashleigh Barty in Beijing at the weekend lifted the Japanese player back into the top three in the new WTA rankings released on Monday. It meant back-to-back WTA Tour titles for the 21-year-old, who won the Australian Open in January but then failed to match those high standards at the next three Grand Slams.
French Open winner Barty retains top spot and even extends her lead following the failure of Karolina Pliskova to get past the first round in China.
Osaka's rise to three means Elina Svitolina, a quarter-finalist in Beijing, slips to four.
US Open champion Bianca Andreescu, who lost a thrilling quarter-final to Osaka last week, also climbs a place to number five pushing Simona Halep down to six.
ATP rankings as of 7 October:
1. Ashleigh Barty (AUS) 7,096 pts
2. KarolÃna PlÃÅ¡kovÃ¡ (CZE) 6,015
3. Naomi Osaka (JPN) 5,621 (+1)
4. Elina Svitolina (UKR) 5,525 (-1)
5. Bianca Andreescu (CAN) 5,041 (+1)
6. Simona Halep (ROU) 4,962 (-1)
7. Petra KvitovÃ¡ (CZE) 4,776
8. Kiki Bertens (NED) 4,495
9. Serena Williams (USA) 3,935
10. Belinda Bencic (SUI) 3,848
Murray climbs over 200 places
Former world number one Andy Murray climbed over 200 places in the new ATP rankings while Novak Djokovic extended his lead over Rafael Nadal at the top.
Scotsman Murray, who is on the comeback trail after career-saving hip surgery, reached the quarter-finals of the China Open where he lost to eventual winner Dominic Thiem. The run lifted the 32-year-old 214 places from 503 in the world to 289.
He can climb into the top 250 if he beats Juan Ignacio Londero later on Monday in the first round of the Shanghai Masters where Murray is a three-time champion. Djokovic's win in Tokyo at the weekend means the Serb is at number one for the 271st week of his career, one more than Ivan Lendl and trailing only Roger Federer (310) and Pete Sampras (286).
Djokovic heads to Shanghai as defending champion while Nadal, his closest pursuer 1,140 points behind, has had to pull out with a wrist injury he picked up during last month's Laver Cup. Thiem's victory over Stefanos Tsitsipas in Beijing sees the Austrian close to just 50 points behind the Russian Daniil Medvedev.
ATP Rankings as of 7 October:
1. Novak Djokovic (SRB) 10,365 pts
2. Rafael Nadal (ESP) 9,225
3. Roger Federer (SUI) 7,130
4. Daniil Medvedev (RUS) 4,965
5. Dominic Thiem (AUT) 4,915
6. Alexander Zverev (GER) 4,185
7. Stefanos Tsitsipas (GRE) 3,630
8. Kei Nishikori (JPN) 3,040
