Paris: French Open champion Garbiñe Muguruza jumped two spots to a career-high No. 2 in the WTA rankings on Monday, while runner-up Serena Williams remained at No. 1, where she's been for more than three years.
Williams' sister Venus returned to the top 10, going to No. 9 from No. 11 after getting to the fourth round at Roland Garros.
Muguruza's straight-set victory over Serena Williams in Saturday's final gave the 22-year-old Spaniard her first Grand Slam title. It was her second major final, following a loss to Williams at Wimbledon a year ago.
Novak Djokovic, who won his fourth consecutive major title by beating Andy Murray in the French Open final Sunday, added to his lead atop the ATP rankings. Djokovic has more ranking points than No. 2 Murray and No. 3 Roger Federer combined.
Rafael Nadal rose to No. 4, swapping places with No. 5 Stan Wawrinka, who won the 2015 French Open and lost to Murray in this year's semifinals.
Dominic Thiem, a 22-year-old from Austria who lost to Djokovic in his first Grand Slam semifinal, climbed to a career-best No. 7 from No. 15.
In men's doubles, Nicolas Mahut is the new No. 1, going up from No. 2. The 34-year-old Frenchman is best known for participating in the longest singles match in tennis history, a 70-68 fifth-set loss to John Isner at Wimbledon in 2010.
India's doubles specialist Rohan Bopanna entered the top 10 in the men's doubles rankings on Monday to secure a direct entry at the forthcoming Rio Olympics.
Bopanna gained a place in the latest top 10 by default after he and Romanian partner Florin Mergea lost in the French Open quarter-finals.
The defeat of defending French Open champions Marcelo Melo and Ivan Dodig in the semi-finals ensured Bopanna's return to the top 10.
Veteran doubles specialist Leander Paes moved up five slots to 46.
Bopanna now can choose his partner for the men’s doubles event among Paes, Purav Raja (103) Divij Sharan (114), Saketh Myneni (125), Jeevan Nedunchezhiyan (134) and Mahesh Bhupathi (164).
In the women’s doubles rankings, Sania Mirza maintained joint world top position with Swiss partner Martina Hingis.
