LONDON, England (AFP) — World number one Novak Djokovic stormed into the Wimbledon last-16 yesterday, while Laura Robson became the first British woman for 15 years to make the fourth round.

Top seed Djokovic, the 2011 champion, destroyed French 28th seed Jeremy Chardy, 6-3, 6-2, 6-2 in just 86 minutes.

He fired 38 winners, eight aces and committed just three unforced errors.

Djokovic will tackle veteran Tommy Haas for a place in the quarter-finals, just weeks after he beat the German in the French Open quarter-finals.

But 13th-seeded Haas beat the Serb star in Miami this season and also got the better of him in the Wimbledon quarter-finals in 2009.

Spanish fourth seed David Ferrer, a quarter-finalist last year, beat Ukraine’s Alexandr Dolgopolov 6-7 (6/8), 7-6 (7/2), 2-6, 6-1, 6-2.

Ferrer will face Croatia’s Ivan Dodig, the world 49, for a place in the quarter-finals.

In the women’s draw, Polish fourth seed Agnieszka Radwanska, the runner-up to Serena Williams last year, defeated Madison Keys of the United States, 7-5, 4-6, 6-3

She will face 2010 semi-finalist Tsvetana Pironkova of Bulgaria who defeated Petra Martic of Croatia, 6-1, 4-6, 6-2.

Chinese sixth seed Li Na survived a roller-coaster of a battle to edge Czech veteran Klara Zakopalova, 4-6, 6-0, 8-6.

Next up for Li is Italian 11th seed Roberta Vinci who saw off Slovakia’s Dominika Cibulkova, 6-1, 6-4.

Women’s 2011 champion Petra Kvitova, the eighth seed and highest ranked player in her half after the exits of Maria Sharapova and Victoria Azarenka, reached the fourth round with a 6-3, 2-6, 6-3 defeat of Russian 25th seed Ekaterina Makarova.
