Serena ups lead in WTA, Djokovic atop ATP

London - Serena Williams has widened her lead at No 1 in the WTA rankings with her fourth consecutive Grand Slam title at Wimbledon, now holding more than twice as many points as No 2 Maria Sharapova.

Novak Djokovic's third championship at the All England Club allowed him to retain his healthy lead atop the ATP rankings on Monday over No 2 Roger Federer, the man he beat in the final.

Sharapova, who lost to Williams in the semi-finals, rose two spots, while last year's champion, Petra Kvitova, slid from No 2 to No 5 after exiting in the third round.

Garbine Muguruza, the 21-year-old from Spain who was the runner-up to Williams, moved into the top 10 for the first time at No 9, an 11-spot rise.

The men's top 10 remained unchanged, including Andy Murray at No 3, and Rafael Nadal at No 10.
