LONDON (AFP) - World number one Novak Djokovic racked up his 30th successive Grand Slam victory on Wednesday when he brushed aside Adrian Mannarino 6-4, 6-3, 7-6 (7/5) to reach the Wimbledon third round.

The defending champion, bidding for a third consecutive title at the All England Club and fourth in all, will face either American 28th seed Sam Querrey or Thomaz Bellucci for a place in the last 16.

Djokovic's match was played under the roof of Centre Court as heavy rain brought chaos to the schedule, allowing just 15 minutes of play on the outside courts.

Don Budge holds the record for successive Slam matches won, reaching 37 in 1938.

French left-hander Mannarino was celebrating his 28th birthday on Wednesday.
