India's Sania Mirza mantained her numero uno position in the latest WTA women's doubles ranking following her recent victory in the Pan Pacific Open in Tokyo, partnering Barbora Strycova of Czech Republic.
Sania (9730) continued to be world number one in doubles but only five points separate her from her estranged partner Martina Hingis (9725).
Sania and Strycova had earlier ousted Hingis and CoCo Vandeweghe in the final of the Cincinnati Open last month.
Sania and Strycova have lost just once since pairing up in Cincinnati, reaching the quarterfinals of the US Open and taking home a second title at the Pan Pacific Open.
Among Indian men, Sakth Myneni is the highest place singles player. Myneni, who entered the main draw of the US Open after winning three rounds in the Qualifying event, dropped a rung to be placed 138th in the list.
Second highest-ranked Indian singles player Ramkumar Ramanathan, who featured in the recent Davis Cup tie against Spain, plummeted 10 places to 229, while out of action Yuki Bhambri dropped a whopping 62 places to be placed 282nd in the chart.
In the men's doubles chart, Rohan Bopanna is static at 18th, while veteran leander Paes has moved four places to 60th.
Halep into 3rd round
WUHAN: Former French Open finalist Simona Halep took less than 70 minutes to reach the third round of the Wuhan Open, advancing Monday when fellow Romanian Irina-Camelia Begu retired in the second set of their second-round match.
The No 4-seeded Halep was leading 6-3, 2-0 when Begu retired with a back injury amid warm and humid conditions. Halep, who skipped the Pan Pacific Open in Tokyo last week because of a hamstring strain, had a first-round bye at Wuhan.
In first-round matches, 2014 champion Petra Kvitova opened with a 6-1, 6-3 win over Jelena Ostapenko and set up a meeting with Elina Svitolina, who rallied from a break down in the third set to beat Bethanie Mattek-Sands 4-6, 6-3, 6-4.
"This was the fourth time we've played this season and I'm glad now it's 2-2," Kvitova said. "I know how difficult it can be to play her and how dangerous she is."
No. 10-seeded Dominika Cibulkova had a 6-2, 2-6, 6-3 win over Alize Cornet and Yulia Putintseva was leading 6-1, 4-1 when Anastasija Sevastova retired from their match.
Johanna Konta, the 11th seed, had a 6-1, 6-2 win over Annika Beck, and Madison Brengle advanced after leading 6-3, 2-1 when British qualifier Heather Watson retired because of a stomach complaint.
Top-seeded Angelique Kerber is in action on Tuesday against Kristina Mladenovic, who had a 7-6 (5), 6-3 first-round win over CoCo Vandeweghe.
Serena Williams, who was replaced by Kerber at No 1 in the rankings with her run to the US Open title, has withdrawn from the tournaments in Wuhan and Beijing because of an injured right shoulder.
