Serena keeps calm and carries on past Giorgi

Serena keeps calm and carries on past Giorgi

Bertens won the first set 6-3 and was close to victory in the second before losing it 5 games to 7.

Serena Williams of the United States celebrates winning a point during her women's singles match against Russia's Evgeniya Rodina, on day seven of the Wimbledon Tennis Championships, in London, Monday July 9, 2018.

Williams responded by raising the intensity level and began striking the ball with ferocious power to break Giorgi's serve for the first time on her way to levelling the match.

Williams, now the world number 181 having slipped down the rankings following her maternity leave, is the lowest-ranked player to reach the Wimbledon quarter-finals in the open era.

Kerber came out on top in a spectacular 25-shot rally to force match point number seven and finally got the job done as Kasatkina netted a forehand, the German a relieved 6-3 7-5 victor.

Serena Williams set a new record but played down title talk as she eased into the last eight at Wimbledon. After the first set, I just said, let's go three sets. This time around focus was on whether Williams would be seeded (she was) and where she would land up in the draw.

After claiming a 19th consecutive match win at the tournament she won in 2015 and 2016 but missed previous year, she said she still had a way to go to regain her top level.

With all the top 10 women's seeds now out, Williams is hot favourite to win an eighth title.

"It's weird. Sometimes I feel, 'Man, I'm in trouble.' Sometimes I feel, 'I can fight.' For whatever reason, today I was so calm", said Williams, who has been wearing compression leggings as a precaution after a blood-clot scare following her daughter's birth. It's like today, I hope I get off to a good start, go from there.

Asked if it had been a flawless display, former world number one Williams said: "I'm a perfectionist".

On Tuesday, No. 11 Kerber will play No. 14 Daria Kasatkina, and No. 12 Ostapenko faces 2014 Australian Open runner-up Dominika Cibulkova.

"This is tennis. Nobody is walking on the court saying OK, I'll give you a free match".

Rapper Drake was part of Williams' entourage on Centre Court, but the American was coy on when her friend Meghan Markle, the new Duchess of Sussex, might be coming to watch.

Having crashed out in the first round at Wimbledon for five consecutive times, Goerges' emotions spilled over at the end of the match after she embraced Bertens at the net.

Goerges, seeded 13th, faces seven-time Wimbledon champion Serena Williams on Thursday for a place in Saturday's final.

Here is a look at some of the key talking points for the women's last-four matches. She missed Wimbledon a year ago because she was pregnant, and she went about 16 months between Grand Slam tournaments, so her ranking is just outside the top 180.
