I’ve known Jo Konta's coach Wim Fissette since I was 10/11/12 and we practiced together a lot when we were younger. Wim was a person who wasn’t really a coach but he was able to hit well so he started out as my hitting partner for a few years.

We were always good friends and it was important to me to have a good person on the side of the court. And then when I started my comeback he kind of got upgraded from hitting partner to coach and that was it.

He’s not firm, he’s at times I think I taught him a lot how important it is to communicate with the player. I’m an open player and I like to discuss the things that are going on.

Since I retired and he and I split up it’s nice that he’s getting good opportunities to work with great players and it’s nice that I could help him out like that.

Up next?

One Johanna Konta. And her opponent, Simona Halep, is bidding to become world number one.

Don Wimble: Shame to see the end of Ostapenko's run. Great entertainment since R1 of the French Open.

Chanice Hird: The oldest woman in the draw and still bossing it on centre court! My girl Venus has still got it! Well done

Jan Sez: Great performance from Venus next up Jo Konta...how long before they mention muffins!!

Ostapenko is just getting started. She had a fantastic win at the French Open. She needs to shorten some swings for the faster-playing grass and improve her second serve but the sky is the limit.

We'll be seeing her again.

OK, so this photo below is of Coco Vandeweghe clearly frustrated, but let's suppose it's a scream of delight. Why?

Because she's only gone and achieved her first break of the match - taking the first of three opportunities as Rybariokova inexplicably lets a bit too much rip on a topspin forehand.

Back of the net!

Venus equals sister Serena on 86 match wins at Wimbledon. Only Martina Navratilova (120) and Chris Evert (96) have more among women in the Open Era.

Venus is the only one who's done it before and that really pays off.

Ostapenko has done well to get into the last week.

Until you win it the first time you don't know if you can and that doubt can add to you on court.

Can she win it again? Why not. She looks composed and controlled on Centre Court, very much a home from home for the five-time champ.

She gives a trademark pirouette and salutes the crowd, who loved that win.

Will we see her on Saturday in the final?

Two easy service games held by both and now it's Vandeweghe to try to hold to stay in the first set.

Good old school serve and volleying from the American - it's 15-15.

Rybarikova then produces the lob of the match so far - admittedly, it's the first - to take it to 30-15 on her opponent's serve.

Pressure Coco? Yes - a double fault follows followed by a good solid return from the Slovak that her superior opponent 'on paper' fails to deal with.

First set Rybarikova.

Ostapenko has hit 20 unforced errors now, and her reaction at the end of that game was to turn and shout at her coach in the box. A frustrating time to fall apart.

Venus looks super calm in context. Unmoved in her seat as she prepares to serve for the match.

She's won 85 times before on these courts...

Ostapenko induces an error from Williams with more big hitting out wide, but then goes wide when well placed to win. 'That's the way she plays' is the chat in the comms box. Too right, if it's there to be hit it will be.

Oooh but she hits the net and gifts Venus two break points. A bad time in the set to do that! Into the net! Venus a game away...

Williams serving to stay in the set then, Ostapenko hoping to take us to a decider. Williams lands one of those big serves down the middle but Ostapenko somehow returns it to her bootstraps, cracking hitting to win the point.

Venus strays wide, 15-30, and the hint of a set-point chance? Ace to go 30-30, champion's response.

Ostapenko goes for broke on her next return and is wide, inches from being unplayable though, and Venus holds.

Rybarikova is spending about two minutes on her service games.

You've barely got time to type...

She's the type of person you wouldn't know changes the gears in a car - smooth.

Her first serve points success is currently at 80%.

Akhilesh Sivaraman: Ostapenko's power is one thing but her control is often just as astounding.

Fraser James McInnes: Watching Ostapenko is a breath of fresh air. It's often said about a player going for every shot but she literally does.

Ostapenko - the Latvian pocket rocket - lands some beautiful, clean winners on her way to another hold.

The 20-year-old is going to make the five-time champion serve to stay in the set.

Rybarikova - the world number 87, that's right, 87! - looks at so much ease playing from the back of the court. It's a very languid style.

And despite losing a point, she follows up with keepy-ups before dinking the ball back to the ball girl.

Vandeweghe is 40-30 on her serve before she comes into the net to slap the ball past the reach of her opponent.

Time for a breather.

Venus Williams ends Ostapenko's run of three consecutive games by holding with only one point dropped.

She sees it out with a 113 mph second serve.

We're level-pegging once again.

The way Venus Williams has been playing this looks like a temporary hiccup but Ostapenko has picked her game up.

Perhaps Venus got a little bit nervous in seeing the finish line,
