Halep adjusts her racquet strings as a backhand slice hits the net post and lands back on her side.

Out from Halep after a rally that Konta, really, had no right to still be in! Ridonkulous stroke play, the ball being pushed wider and wider, before Halep made the error. 40-0!

Halep looks a little miffed, to say the least and throws the kitchen sink at a backhand winner, before Konta gifts her a point with a return into the net.

Long return from Halep! Konta holds!

Tina Knights: Just hold your serve, Jo. Just hold your serve.

Joanna: What a cracking advert for women's tennis this is, high quality and great shotmaking.

Anthony McMahon: Seriously one of the greatest women's tennis games I've ever seen and they're both still at it.

Mikeh7: Not sure about Halep being world no 1.but Konta must be close to the top spot in the very near future.

John Hutchinson: Surely one of the best women's games at Wimbledon - both Konta and Halep are playing so well.

Meanwhile, Konta fans are getting a right soaking on Henman Hill - or is it Konta Kop...?

If you don't think a crowd can be the difference between winning and losing, you haven't watched enough tennis.

It happened in the tie-break and it's part of why Halep just got broken. You could feel it seep into her bones.

There's a massive smile on Virginia Wade's face as she watches on from the Royal Box.

Now. Can Konta back up the break with a hold?

That's the way to play that game, she got that perfectly right! She made her returns and then dictated the play. She sent out a big message - she is in the ascendancy now.

I think it's the attitude and the mind set that will prove the difference now in this match.

Yes she can!

She keeps pushing Halep out wide and eventually the error comes! First break goes Konta's way, and she still looks as cool as a cucumber.

Fingernails being bitten all around Centre Court as the crowd look on. It's so quiet, the only sound making any impact is the thud of the ball flying off the racquet.

Oh, hello, two break points Konta! She's been pushing Halep out wide and twice the Romanian lashes returns into the net. Can Konta take this chance?

Best tweet of the day.

Konta has been so good up at the net today, another point going her way with a little forehand dink.

Long with the backhand goes Halep, and Konta keeps her steel, crouching low on the baseline, to draw the eventual error out of the Romanian.

Ian B: This match would have graced any women's final, better than most, stunning

George Maudsley: Also travelling while following Konta! 35,000 feet in the air from San Francisco to Santiago, Chile. Come on, Jo!

If you looked at the scores now, you'd think this was John Isner v Ivo Karlovic.

Simona Halep makes things look very, very easy at times.

A double fault is Konta's only chance to get on the board as Halep whizzes through her service game.

It's amazing how many balls Halep picks up. Yes, she is fast on the court but it's more than that. She picks up cues from her opponent and gets a read on where the shots are going.

She has the desire and the spirit to get there

Backhand volley from Konta - but she squanders another advantage with a drop shot that finds a home in the net!

Up at the net again and there's a scream from the crowd as Konta looks to be beaten - but another sneak little tap return has the crowd cheering.

And a smash to hold! What a game.

Andy Powell: If you've just tuned into @BBCOne, external expecting the news, Johanna Konta IS the news.

Daniel Woodley: An incredible game of tennis! A fantastic advert for the game. Come on @JoKonta91, external! The whole of Britain is behind you.

Konta has Halep chasing from left to right, always behind the rally, before lashing a forehand winner straight down the line.

The first advantage comes and goes, Konta's forehand gong long, but she responds with another fiery backhand slap.

And again, Halep keeps herself in the point with a passing winner. Third deuce ahoy.
