Ned Holmes: Unfortunate tie-break for Konta a few chances slip through her fingers there Halep superhuman in her returning
Lee Ferguson: It is an awful long way for Jo Konta now!! But i still believe she can do it!!
*Halep 7-6 (7-2) 0-1 Konta
Not a great start from the Briton. She makes a clanger of a volley and it overshoots the chalk by a long way.
But from 0-30, Konta recovers.
She lands a sturdy ace to level, then she slaps down a leaping volley, before finishing off beautifully on the line.

Konta has to get the fans into the match a bit more. I think that would help her and she should ask them for a bit more encouragement from time to time.

Bjorn Borg told me that he never once felt tired during a match. I bet Halep is the same.
She plays a 20, 30-shot rally and then steps right back on the court. Konta just tailed off during the tie-breaker.

There were a couple of points there that Konta should have won - that slap from when the ball was hanging in the air was the main one.
Konta's come back from a set down already at Wimbledon. Can she do it again? She'll serve to start the second set.

Halep's forehand winner brings her four set points.
She needs only one chance. Konta hits high and over, first blood to the Romanian.

There's so much intensity out there. What a match! One of the best of the tournament so far.
*Halep 6-6 (5-2) Konta
Halep chunters furiously to herself after that double fault, but that'll raise her spirits, an attempted slap from Konta flying wide as she takes the ball from up in the air.
Quick change of ends - and a big cheer for Konta - but that forehand from Konta has found the net!
Halep 6-6 (3-2) Konta*
After that remarkable winner, Halep takes a deep breath and is back on serve.
Once again she overpowers Konta, who returns wide.
But she can only land a double fault with her second go. Frustrating for the world number two.

We are seeing phenomenal play from both players. The standard of tennis in this set is sky-high.

What an unbelievable point! Both players are breathing heavily after that.
*Halep 6-6 (2-1) Konta
This would be an excellent time for Konta to keep nailing those first serves.
Halep makes an unbelievable return, charging out wide behind the baseline, but Konta secures the point with an overhead smash.
And again! That is supreme work from Halep, a phenomenal return right up at the net as she clings onto the rally, and the ball bounces just on the line! The fitness on show here is amazing.
Halep wins 'unbelievable point'

Roz Harris: Due to having the best job I'm home cheering on Konta to the semi's come on Konta
*Halep 6-6 Konta
These two are hitting the ball so flat. It's getting thwacked back and forth and both players benefit, Konta returning wide before a winner goes past Halep.
A lovely little backhand volley from Konta beats Halep before the Brit slices a return from out wide into the net.
There's that first serve - Halep raises her arm in a "what can I do?" sort of motion - before a big winner sees out the game
Hello, tie-break!

Was once flat!
The ground staff walked on to the covers, did something or other and now the covers have transformed into a giant tent - beat that Optimus Prime!
Anyway, that's not good news as far as watching play in the foreseeable future.
It was Rybarikova 6-3 2-2 Vandeweghe when we left it about 40 minutes ago.

Both players are finding great depth in their shots. It's terrific ball striking.
Halep 6-5 Konta*
Konta has missed one first serve in 26 so far. Excellent work from the Brit.
She'll serve now to stay in this set and force a tie-break.
