Johanna Konta beats Simona Halep 6-7 (2-7) 7-6 (7-5) 6-4 in quarter-finals
Konta is first British female in the semi-finals since Virginia Wade in 1978
She faces Venus Williams, who beat Ostapenko 6-3 7-5, in last four
Rybarikova beats Vandeweghe 6-3 6-3
Muguruza beats Kuznetsova 6-3 6-4
Djokovic beats Mannarino to reach men's last eight
Williams 1-0 Ostapenko
We are under way! Venus to serve first, Ostapenko punishing a second serve with a cracking forehand winner from deep. Don't serve there!
Venus still so strong on her first serve though, time maybe does wait for some after all. An ace on the line, and another! Three aces in the game and she holds.
Williams v Ostapenko
It's been said to death over the last few weeks, but the women's draw really is wide open. There is no real reason why Venus couldn't do it again.
Of the last eight, four players remain who have won a Grand Slam title previously: Svetlana Kuznetsova, Ostapenko, Garbine Muguruza and Williams.
Ostapenko, 17 years Venus' junior, is perhaps the form player of the lot after her victory at the French.
Muguruza 6-3 2-2 Kuznetsova*
Disappointing from Kuznetsova - she's 30-15 down, comes to the net with the point at her mercy and finds the netting with her return.
It's 40-15 and now game for Muguruza thanks to a backhand winner.
It's all going to serve in the second set.

Nine-time Wimbledon singles champion
Venus has a really good chance of winning Wimbledon again. I raise my hat to her.
She has been really firing on her first serve and winning everything at the net. She has the best swing volley in the game.

Image source, BBC SportNo, they haven't installed an ice rink at Wimbledon - not yet, anyway. This is the giant cover that covers three of the 16 practice courts at Aorangi Park.
When the weather makes these courts unusable, players don't have to go far - there are five indoor courts at the All England Club for them to go and have a hit.
Williams v Ostapenko
Born in early June 1997, Latvian Ostapenko was only a few days old when Williams made her debut at SW19.
At 37-years-old, the evergreen Williams - a five-time champion - is the oldest woman to go this far into the draw since Martina Navratilova in 1984.
Ostapenko comes into her third Wimbledon off the back of a surprising victory at the French Open. She was unseeded when she beat Simona Halep to win her first major at Roland Garros last month.
She's currently on an 11 match winning streak in Grand Slams.

Image source, Getty ImagesOstapenko was so fearless in Paris and at times she was making a lot of unforced errors, but mentally she wasn’t letting it get to her which was incredible to watch.
She’s still in the draw, still fighting and still doing her thing with a lot of confidence. Players are going to have to beat her if they want to get through and do I think she’s going to win it? I don’t know.
There are a few players who are a little more consistent. It’s so hard because there are so many players who I think can beat each other. I can’t pick one winner, that’s the great thing about it and you can’t predict who’s going to still be in the draw in a few days.

Job done. More beaming grins from Jamie Murray and Martina Hingis, and a double air kiss, as they hold to love to take their first match point.
The Scot-Swiss doubles dream team are into the last eight, where they could face British pair Ken Skupski and Jocelyn Rae.
Williams v Ostapenko
What were you doing in June 2000?
I had just done my GCSEs, was convinced that McManaman, Ince, Scholes and Beckham were going to crack the Euros and was enjoying Coldplay's debut album immensely.
Venus Williams was winning her first Wimbledon title against Lindsay Davenport, as our state-of-the-art live text described beautifully.
Can she win a sixth crown this year at the grand old age of 37?It seems unlikely. Improbable. Impossible?
Nope. She can make the last four this afternoon...
Williams v Ostapenko
Here comes Venus Williams!
Garbine Muguruza wins the first set after 32 minutes after a great rally with Svetlana Kuznetsova at set point.
Muguruza wins the set
Djokovic wins
Image source, ReutersNovak Djokovic on BBC One: "It was a long day yesterday for both of us waiting for an entire day. It is what it is. We got on the court today and we could play under the roof.
"I'm glad it's all done and looking forward to the next one. I haven't dropped a set yet on grass, I have been feeling really good. I am motivated to go as far as I Can, it's one of my favourite tournaments.
"We'll see on the shoulder. It has something which has been dragging back and forth for a while but I am still managing to play. There are no clear favourites any more.
"I mentioned that there is a hole in the middle of the court to the umpire and he asked me to show him which I did at the end. He was not too pleased. The courts are not that great this year, many players feel the same. I am sure the groundsmen are the best in the world, but grass is the most complex surface to maintain."
Muguruza 6-3 1-1 Kuznetsova*
Yes...you!
There's great embarrassment in the crowd - well we're hoping he's embarrassed - as a spectator fails to hold on to a simple catch as the ball lands in his direction.
Brief laughter ensued.
Back on the court of play, Muguruza saves another break point by coming into the net after moving Kuznetsova wide right with a backhand.
The Spaniard then closes out the game - she is currently laughing at danger. Ha ha!

It's lovely to see people having fun in the workplace. Jamie Murray and Martina Hingis are having a ball out on court two, with teeth-bearing, wide grins greeting the end of virtually every point.
Suppose it is easy to be happy when you're cruising towards victory.
The top seeds have just broken serve again and are two games away from the quarter-finals.
Mannarino 2-6 6-7 (5-7) 4-6 Djokovic
So Novak Djokovic comes through another match without dropping a set. Very impressive.
Up next: 11th seed Tomas Berdych.
The winner of that match will play Roger Federer or Milos Raonic.

Then she decided to live back in her own country - Russia - she reinvigorated herself and injected extra energy into her tennis.

Novak Djokovic is a three-time champion but he is showing people he has concerns about his shoulder, his back, his ankle and that he has a fragile outlook. He should be more poker-faced. We have no idea what Roger Federer is feeling, do we?

Your man claims another match point and takes his place in the quarter-finals when Mannarino nets after an exhausting rally.
A fitting way to end, really.
Djokovic breezes through to quarter-finals
Fresh from knocking out the number one seed Angelique Kerber, Garbine Muguruza is looking in good nick against Svetlana Kuznetsova. Watch her impressively breaking to love below.
