Serbia's Novak Djokovic took his latest winning streak to two matches with an emphatic win over South African Kevin Anderson in the Wimbledon second round.
The world number two may struggle to match the 41 consecutive victories with which he began the year before losing in the French Open semi-final but his form so far suggests no hangover from his Paris loss to Roger Federer.
After scorching into a 5-0 lead after 15 minutes he routinely dispatched the towering Anderson 6-3 6-4 6-2.
Several other seeds prospered as the fourth day began under bright sunshine with just a few scattered showers to worry the organisers, who have battled fickle weather so far.
Francesca Schiavone, one of seven grand slam champions in the draw, beat Barbora Zahlavova 7-5 6-3.
