No sign of a chance for Andy Murray to start strutting his Centre Court stuff.

We are just a shade shy of two and a half hours as Petra Kvitova turns her fire on the Venus Williams serve once more.

Jeremy Chardy is into the fourth round of Wimbledon for the first time, downing the likeable Sergiy Stakhovsky in four. Either Marin Cilic or Tomas Berdych next for the Frenchman.

While they are going hammer and tongs out on Centre Court, Agnieszka Radwanska has come buzzing in low under the radar to make the fourth round in 57 minutes.

"Petra Kvitova had porridge every morning for breakfast when she won Wimbledon, with pineapple. I ate porridge every morning last year when I won too, with goji berries. So porridge is the breakfast of champions."

What about if you accessorise your porridge with black pudding though?

Love-thirty on the Petra Kvitova serve. The sniff of a break has got them perky as meerkats on Centre Court.

At ease spectators. Kvitova locates the sweet spot - battering serves and then slipping a fine top-spinning angled winner past Venus Williams to see off the danger.

Just a reminder, not that you need it I'm sure, but Andy Murray is next up on Centre Court...

"I favour Petra Kvitova, but only by a very small margin. Venus keeps playing the ball to Petra's forehand, but as Petra is a leftie, she needs to play to her back hand."

Petra Kvitova chucks down a service game to love. Gauntlet across the chops of Williams.

The Czech is coming on strong and serving first in the decider looks like it is suiting her.

Centre Court now bathed in late evening sunshine by the way.

Those morning predictions of rain, hail and high water? You can file them alongside Michael Fish's 1987 prediction that there was no hurricane on the way before every third roof tile in Britain was dislodged.

Twenty-six minutes into the third and deciding set on Centre Court and it is more attritional than a glass-shard face scrub.

Petra Kvitova noses ahead on serve, but this might come down to who can keep the lid on their nerves down the home straight.

Alexandr Dolgopolov is on a roll. He breaks Grigor Dimitrov to seal the third set with a smoking forehand pass.

No more room for manoeuvre for Mr Sharapova.

Alexandr Dolgopolov's serve is a mixed bag, raining down 14 aces against Grigor Dimitrov, but only landing between the lines 58% of the time.

It is doing the trick at the moment though. It's Ukranian owner is a break to the good in the third.

A quick update from out and about.

Radwanska 6-2 De Brito: Agnieszka Radwanska, the 2012 runner-up, seals the first set of her meeting with Portuguese Michelle Larcher de Brito.

Stakhovsky 3-6 7-6 (7-4) 3-6 Chardy: Jeremy Chardy takes the third set, but that one feels like it has plenty of legs to me.

Fabio Fognini has had an interesting week at the All England Club, picking up a record fine for damaging a court, abusing an official and making obscene gesture, before losing in five sets to Kevin Anderson on Friday.

"I like it here because I'm really fast, so I can run really well," said the Italian. "I really love it. The only thing I don't like is the rules. Wimbledon's rules. White colour.

"Maybe if you see today I crash the racquets in my knee because maybe the court is really soft. I can damage a lot."

You can probably damage your knee quite a lot as well Fabio. Take it out on the courtside chair, that always looks suitably dramatic.

"Credit to Kvitova because she had been making too many unforced errors and had been unwilling to take some pace off just to get the ball back into play, but she finally made that adjustment."

A double-fault to surrender a set? That was the type of crime that I had Petra Kvitova pegged for, but Venus Williams is bang to rights as she over-reaches, trying to find an ace in her locker, and finds only the top of the net.

Argentina's Leonardo Mayer has seen off Andrey Kuznetsov to book his place in the fourth round.

A good few days work for Russian world number 118 Kuznetsov though who beat Britain's Dan Evans and seventh seed David Ferrer to make the third round.

Lleyton Hewitt has broken the Open Era record for the most five-set matches played at Grand Slam tournaments. He played his 42nd five-set match at Wimbledon on Friday, losing to 15th seed Jerzy Janowicz 7-5 6-4 6-7 (5-7) 4-6 6-3 in the second round, after the match had been suspended overnight on Thursday.

The Australian previously shared the record with Andre Agassi on 41 five-set matches.

Hewitt has won the second most five-set matches in the Open Era. He has a five-set win-loss record of 26-16, behind Pete Sampras who had a five-set win-loss record of 29-9.

We are into a tie-break on Centre Court and on the opening point Petra Kvitova wallops away a cross-court return to take a mini-break.

She holds the next two serves and is 3-0 to the good...
