Defending champion Novak Djokovic breezed into the Wimbledon last 16 as he dropped just seven games in a convincing win against fellow Serb Miomir Kecmanovic.
The top seed has not lost a grass-court match since being beaten by Marin Cilic in the final at Queen's in 2018.
The six-time SW19 champion plays Dutch wildcard Tim van Rijthoven next.
"I thought I started off very well, with good intensity and good focus," said Djokovic, who reached the Wimbledon last 16 for the 14th time, which leaves him trailing only Roger Federer (18) and Jimmy Connors (16) in the record books.
