*Halep 5-7 4-5 Kerber
Angelique Kerber cannot close out the match on her serve.
Simona Halep locks into the game like a tick on an unprotected calf. Can she hold her serve though?
Only three times so far this afternoon has she kept her end up.
The exchanges between Halep and Kerber are unreal. Neither player was deserving of losing this point.

Delightful stuff from Angelique Kerber as she lures in Simona Halep and then pings away a winner into the open acres behind the Romanian.

Yaroslava Shvedova slaps her forehead with the palm of her right hand as she sits down for a breather. She knows she has blown a golden chance there.
Can she recover? Venus was pushed to three sets in rounds two and three after winning the opener. Still plenty of hope for the Kazakh.

Simona Halep is back in the Centre Court room.
There were some reading the rites over the Romanian after that Angelique Kerber break in the previous game.
But she has nibbled her way back into second set.

Halep is going to have to come up with something special to get back into this match.
Halep 5-7 2-4 *Kerber
Angelique Kerber kicks down the door on the Simona Halep serve, racking up 0-40 and three break points.

What a game for Halep to get herself out of.
Kerber made a mess of that volley.
Halep was so far out of the court there was no way she would have got anywhere near it, if it was within the line.
V.Williams 6-6 Shvedova
To a tie-break we go on Court One.
Venus Williams decides to change racquet for the occasion.
Halep 5-7 2-2 *Kerber
The second set is a lot more conventional after the bohemian, hippy-dippy affair that was the break-fest first.

The baseline rallies are getting longer. The returns are getting harder. The grunting is getting louder. Venus outpowers her opponent - physically and vocally - to move within a break of the opening set.

Jamie Murray and doubles partner Bruno Soares - seeded third - have finally prevailed in a mammoth contest with Mate Pavic and Michael Venus.

You've got to love a left-handed sportsman or woman. They just seem to have that extra class, don't they?
John McEnroe, Monica Seles, Brian Lara... heck, even Gareth Bale is left-footed.
Angelique Kerber, on Centre Court right now, is also in the club.
Left-handers have a good record at Wimbledon and our colleagues at BBC iWonder, with help from former Greg Rusedski, have produced a fascinating study into that very subject.
V.Williams 5-5 Shvedova
Venus Williams earns a break and set point against Yaroslava Shvedova but the Kazakh manages to claw her way back into the game and sees it out with a double-handed backhand.
We're back on level terms over on Court One. Watch the action here.

Halep 5-7 Kerber
Lindsay Davenport
Former Wimbledon champion on BBC TV
Halep is going to have to figure out how to be more consistent with her service games.
She got a little nervy there at end and that last double fault felt inevitable, Kerber was putting so much pressure on every service game.
Kerber has been player willing to take more risks so far and it has paid off.
She has been inside the baseline more and that has been the difference.

Well that didn't last long. Yaroslava Shvedova's break slithers out of sight instantly. We're back on serve.
I get the feeling that the Court One crowd are more behind the Kazak rather than Venus Williams. Probably because a) the British love an underdog and b) they want to see a contest.
