World number one Novak Djokovic stormed into the Wimbledon last-16 on Saturday 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.
"I felt very confident to step onto the court and everything went my way," said Djokovic after his 50th career grasscourt win.
"I haven't lost many points on my service games. I did everything I wanted to do. I enjoy it very much when everything works well. It's a fantastic feeling."
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.
Robson came from a set and 3-5 down to defeat New Zealand's Marina Erakovic, 1-6, 7-5, 6-3 and goes on to face Kaia Kanepi of Estonia, a former quarter-finalist.
Robson, currently ranked 38 in the world, will also move into the top 30 after the tournament, the first British woman to break that barrier since Jo Durie in April, 1987.
"I was getting my butt kicked in the first set," said Robson.
"But I told myself just to keep working hard, she will get nervous and that's what happened."
The men's fourth round will feature five men making their maiden appearance at the fourth round stage.
France's Kenny De Schepper, the 26-year-old world number 80, beat Argentine 22nd seed Juan Monaco, 6-4, 7-6 (10/8), 6-4 to book a last-16 spot at a major for the first time.
Poland's Lukasz Kubot, ranked 130, also made the fourth round in 2011, and is the second Pole to reach the last-16 after 24th seed Jerzy Janowicz also booked his place on Friday.
Kubot beat 25th seed Benoit Paire 6-1, 6-3, 6-4 and next faces French world number 111 Adrian Mannarino who has made the last-16 at a major for the first time in 14 attempts.
Left-hander De Schepper will face experienced Fernando Verdasco in Monday's fourth round after the Spanish former top 10 player, now at 54 in the world, cruised past temperamental Latvian Ernests Gulbis, 6-2, 6-4, 6-4.
Russian 20th seed Mikhail Youzhny, a quarter-finalist in 2012, defeated Serbia's Viktor Troicki 6-3, 6-4, 7-5 and goes on to face British second seed Andy Murray.
The lop-sided bottom half of the draw has been caused by the shock early exits of defending champion Roger Federer and Rafael Nadal.
Only four of the top 10 seeds have made it through to the second week.
In the top half, Czech seventh seed Tomas Berdych, the runner-up in 2010, claimed his ninth win in nine meetings with South Africa's Kevin Anderson, coming through 3-6, 6-3, 6-4, 7-5.
Berdych takes on unseeded Australian Bernard Tomic, a quarter-finalist in 2011, who put out French ninth seed, Richard Gasquet, 7-6 (9/7), 5-7, 7-5, 7-6 (7/5).
Meanwhile, Ivan Dodig of Croatia reached his first fourth round at Wimbledon when Dutchman Igor Sijsling quit trailing 6-0, 6-1, 1-0.
Sijsling's withdrawal equalled the injury pullouts record of 13 from 2008.
Italian 23rd seed Andreas Seppi beat Japan's Kei Nishikori, 3-6, 6-2, 6-7 (4/7), 6-1, 6-4, also for a maiden last-16 place.
Seppi will face Argentine eighth seed Juan Martin Del Potro who defeated Slovenia's Grega Zemlja 7-5, 7-6 (7/3), 6-0.
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.
Later Saturday, top seed Williams takes on Japan's Kimiko Date-Krumm.
Williams is on a winning streak of 33 matches and is chasing her 600th tour victory.
Date-Krumm, 42, has reached the third round 17 years after she last did so to become oldest woman to achieve the feat.
