Venus Williams, whose lukewarm Wimbledons earlier this decade suggested a fade, persisted with obliterating that notion on Monday.
Venus will next play against French Open champion Jelena Ostapenko, who has made it to her second and consecutive Grand Slam quarterfinal this year. However, a lot of fans and players were left questioning about the logic behind court scheduling. "There's no other explanation".
"If there's better matches on the women's side than the men's side, you can flip it. That's what I'm doing".
Former runner-up and No. 14 seed Garbine Muguruza claimed the biggest scalp, taking down No. 1 seed Angelique Kerber 4-6, 6-4, 6-4. Simona Halep is showing the tell-tale signs of a victor, the World No.2 is a very consistent player and well-suited to grass courts. She didn't give the French Open champion any chance to maximize her massive first serves and will move into the top 10 Wimbledon. The Spanish will face in the next round the victor of two titles of the Grand Slam, Svetlana Kuznetsova, who easily beat Agnieszka Radwanska 6-2, 6-4 in the first match on Monday.
Since then, Serena's sister has been playing excellently on the grass courts of Wimbledon, showing determination in winning the championship title.
During the earlier rounds, Venus broke down in tears when reporters asked about the vehicle accident that took the life of 78-year-old Jerome Barson.
After Williams secured a double break to love off the back of a resilient hold, and found herself with three match points.
The American, 24th head of the series, has blasted eight aces, compared to zero for the Danish.
Backing up that sort of out-from-nowhere triumph is notoriously hard but the fearlessness of youth has served Ostapenko well and she appears to have paid little attention to the heightened levels of expectation.
"Been working on that serve", Williams said. I just enjoy it more. I know she had an fantastic moment there. Konta will next face Halep. "It's been so good to me".
Djokovic was broken only once, in the second set. That was several months before the birth of her 27th-seeded opponent, who was appearing in the fourth round at the All England Club for the first time.
Mannarino has never before reached the quarterfinals at any of the four Grand Slam tournaments. Pliskova lost in the second round, and Kerber lost in the fourth round.
Federer first reached the Wimbledon quarterfinals in 2001 and then won the first of five straight titles in 2003.
"It's their turf", said Ernests Gulbis, who stood in Djokovic's way in the third round but failed to present too much of an obstacle. "He will not get overwhelmed by the stadium or whatever". It makes it one of the most hectic days on the tennis calendar, and similar concerns from leading women have been heard on the corresponding day in previous years.
Play has started on Centre Court, with the roof closed, and resumed on some of the outside courts at Wimbledon after a rain delay.
Following Venus onto Centre Court is Johanna Konta, who takes on Simona Halep bidding to become the first British woman to reach the semi-finals since Virginia Wade in 1978.
There was a brief rain delay on the opening day of the tournament, but the roof stayed open and the rain went away.
