LONDON, July 1: Top seed Novak Djokovic reached the Wimbledon quarter-finals for the sixth successive year with a 6-3, 6-4, 7-6 (7/5) win over French 14th seed Jo-Wilfried Tsonga on Monday.

Djokovic, the 2011 champion, will be playing in his 21st successive Grand Slam quarter-final when he faces Croatia’s Marin Cilic for a place in the semi-finals.

Djokovic leads Cilic 9-0 in career meetings.

His win on Monday was his 13th in 18 meetings against two-time Wimbledon semi-finalist Tsonga and 11th in a row.

“In the third set he started to serve very well, very efficient, very strong. It was important to hang in there, get into the tie-break,” said Djokovic who fired 44 winners.

“I am feeling good, I had two days off, I could recover a little bit. In the first week I had a couple of tough matches.”

On facing Cilic, the Serb added: “He knows how to play on grass and definitely he has nothing to lose so I look forward to a tough one.”
