Serena Williams earns gritty Wimbledon win against Italian Camila Giorgi

Kiki Bertens celebrates victory against Venus Williams

Ominously, though, Williams remains the player to beat after continuing her stirring comeback from maternity leave with a 3-6 6-3 6-4 win over fearless and unseeded Italian Camila Giorgi.

After a insane and awesome final game Angelique Kerber, the only player to reach at least the quarter-final stage in each of the Grand Slams this season, reached the seventh major semifinal as she beat Daria Kasatkina for the fourth time in her career in seven meetings.

Goerges also battled back from a set down to beat Dutchwoman Kiki Bertens 3-6 7-5 6-1 in the last of the women's quarter-finals.

After all the kerfuffle of the seeding, the scrappiness and fight from Dominika Cibulkova finally petered out at the hands of Ostapenko who is hitting free having unencumbered herself from the burden of defending a Slam title in the first round of the French Open this time around.

German Angelique Kerber stands in the way of a potential dream final for Ostapenko against Serena Williams.

Ostapenko became the first Latvian woman to make the last four at the All England Club with a 7-5, 6-4 victory over Dominika Cibulkova on a windy No. 1 Court.

Speaking after the match about her slow start, the 2017 Roland Garros champion said: "I think the opponent played quite well in the beginning. But I'm still in the draw and I'm playing and just trying to focus on myself", Ostapenko said after her third round on Saturday. "These are the matches I was working for as a kid and to be in the final at Wimbledon is great". Ostapenko, seeded 12th, fired 33 winners to prevail in one hour and 22 minutes. "I didn't expect to do this well in my fourth tournament back", said Williams, who competed in the Indian Wells Masters, the Miami Open and the French Open before this year's Wimbledon tournament.

"To be here, to be in the semi-finals, I always say I plan on it, I would like to be there, have these goals".

Williams' seemingly inevitable march to the final of a women's singles tournament in which none of the top 10 seeds remain continued at pace against Evgeniya Rodina as she eased into the last eight, but the seven-time Wimbledon champion needed to use much more of her reserves against Giorgi.

'We never played, she [Kerber] is one of the players I've never played.

But Serena bludgeoned her way out of trouble, winning 3-6, 6-3, 6-4 to stay on course for an eighth All England Club triumph.

"I still have a long way to go to be where I was". I am just here to be here and prove I am back.

It was to get no better for the world number 50, another quick hold from the 12th seed made it five games on the trot and the Belarusian was quickly staring at the end of her fortnight.

"I don't think Kasatkina has been disciplined enough".

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.

On Monday, the twice Grand Slam champion did not let such expectations weigh her down and she set up a last-eight showdown with Russian 14th seed Daria Kasatkina.

Asked whether she had sympathy for Hsieh, Cibulkova was adamant it was not the Taiwanese player who had been wronged.
