Halep 5-7 Kerber
Simona Halep duffs down a double fault to end this first set on an appropriately bum service note.
Angelique Kerber's hold in the opening game proves key.

Halep definitely made more effort to be aggressive in that game.
She didn't have the mind set of just spinning the first serve in.
Vesely 6-4 3-6 6-7 7-6 3-6 Berdych
Tomas Berdych finally converts a match point at the eighth time of asking to book in for a quarter-final against French mystery package Lucas Pouille.
Berdych was runner-up at Wimbledon in 2011, but has not been as deep since.

The all-Czech fourth-round dust-up over on court three might be close to a conclusion.
Tenth seed Tomas Berdych - a possible semi-final opponent for Andy Murray - is a game away after breaking the Jiri Vesely serve.

Kazakhstan's Yaroslava Shvedova breaks Venus Williams after the five-time champion finds the net with her backhand. That was Shvedova's fourth break point.

Extraordinary scenes on Centre Court as Simona Halep makes a service game stick to the scoreboard.
This match has been as quirky as a Wes Anderson film so far.

Britain's Davis Cup captain Leon Smith spoke to BBC Radio 5 live:
"It’s a brutal schedule. To turn around from Wimbledon, fly over to another country and change surface, it's not easy."
Will Murray play in the Davis Cup?
"He wanted to be named in the initial team. He loves the competition. At the moment the most important thing for him is Wimbledon. He has to see how he feels. If he says he can't do this then of course we'll respect it."

We've already seen our first clenched fist-pump of the afternoon here in Court One. And why not. Yaroslava Shvedova, aiming to reach her first Slam semi-final, saves two break points to get herself off the hook against five-time champion Venus Williams.

Just one hold of serve in the opening nine service games.
It is getting a little silly now.
Just bung it in underarm perhaps? Certainly the overhead action that has served players well for more than 100 years seems to be broken this afternoon on Centre Court.

Adam Stubbings: EIGHT breaks of serve in a row? Can tell these ladies like to play defensively can't you
Jonathan Hextall: Kerber Halep is a great match so far. It's a break fest but the rallies are incredible and entertaining.
Theo Bowyer: Halep and Kerber have certainly brought their protractors to the court judging by the incredible angles they are finding!
Halep 4-5 Kerber
Simona Halep and Angelique Kerber are already putting on a show on Centre Court. This 21-shot rally is a prime example of the quality of tennis.
Fantastic 21-shot rally between Halep and Kerber
Pavic/Venus 3-6 6-7 6-4 6-4 13-13 J Murray/Soares
Britain's Jamie Murray is involved in a right old ding-dong in his men's doubles third round match.
They've had 26 games in the deciding set alone and are about to resume.
You can watch that match conclude on Court 17 right here.

Guess what?
Service holds are rarer than hen's teeth as Simona Halep finds herself 0-40 adrift, battles back to 30-40 and then plants a shoulder-high mid-court bounce into the net.
It should have been routine. Inside she will have to break to stay in the set.

This has basically been a highlight reel.

Where is this one heading?
It is a magical mysterious tour of an opening set as Simona Halep takes it back on serve - in theory at least - with another break.
The Romanian is yet to hold serve however.

Yaroslava Shvedova shows Venus Williams what she is capable of with this beautiful strong forehand early in the first set.
Shvedova's forehand too strong for Venus
Halep 2-4 *Kerber
Just one service hold in six games.
Both players storming the barricades to steal the other's serve with high-quality tennis.

Federer, ever the man of the people, is unruffled. "Rogerrrrrrrrrr! Pleeeeease?!" is the standard request. Not a problem.
The seven-time champ poses with tens of fans, including many junior players, before disappearing off home. Despite spending about 10 minutes dealing with the requests, many of still left disappointed when he disappears down the steps.

Kerber had only been broken three times coming into the match and now she has been broken twice already today.
She have to be more careful where she places the serve and not be too predictable.
I think those stats will change win or lose today.
