It was an incredible day in the office, let's face it, from start to finish.

Naomi Osaka had her foot on the pedal the whole entire match. She had devastating depth on her groundstrokes. She laser-guided every shot. These were all things Daria Kasatkina just couldn't break through - her slices, chips and drop shots just didn't bother her opponent.

That's as clean a match as I've seen in this championships.

This is what Djokovic does to you.

He builds pressure, forces you to go for big shots and makes you make mistakes.

Novak Djokovic finds an almost impossible angle after chasing down a drop shot. Lovely stuff.

Arthur Rinderknech goes long with a backhand. Two break points for Djokovic.

Djokovic goes long so the first break point is saved, but not the second!

Djokovic finds a super return and Rinderknech can't get it back.

That is too passive from Rinderknech. At 5-4 and 30-30 against Djokovic, you have to take it on.

You can't hope or wait for a mistake, you have to make it happen.

A passing shot down the line takes Arthur Rinderknech to 30-30 on Novak Djokovic's serve and within two points of winning the first set.

Djokovic keeps calm, carries on and wins the game with a superb cross-court backhand.

A very good afternoon's work for the 14th seed.

I suspect she will be getting a very good school report from Tomasz Wiktorowski because it will be hard to find any holes in that performance.

But for Daria Kasatkina, the rebuild goes on. It won't be another run to the quarter-finals for her.

Novak Djokovic produced a near-faultless performance to sweep aside Stefanos Tsitsipas two days ago.

He made just the single unforced error in both sets two and three on his way to that statement win.

The Serb isn't quite managing to hit those heights so far today. Arguably, he isn't being allowed to.

Standout performance so far goes to the chap who has just executed a one-handed catch, before standing up and taking a bow to cheers from the crowd. The stuff dreams are made of.

There's some audible gasps as Naomi Osaka hits the deck, but she's straight back up and seems unfazed as she works her way to match point.

And there it is. A quick shake of the fist before meeting a dejected Daria Kasatkina at the net.

The Russian-born Australian was well-beaten, but she gets a warm applause as she exits Court One.

Those two breaks earlier in the set are starting to look like real anomalies because otherwise it's been fairly straightforward stuff for both players to win their service games.

Wild from Daria Kasatkina - that forehand only just bounced before the back wall.

Two match points for Naomi Osaka, who hasn't really had to leave second gear.

A hold to love for the seven-time Wimbledon champion.

Daria Kasatkina certainly hasn't thrown in the towel in this match, earning more applause from Naomi Osaka for a well-placed deep forehand. 15-all.

Osaka responds by leaping into a forehand drive volley on the edge of the service box, burying it with oomph, and closes out a simple hold to 15.

It was a messy, scrappy and long three-set match. Not vintage Bencic but she got the job done.

It's very rare for Djokovic to have those lapses in concentration.

Up 3-2 with a break, he had the opportunity to stamp his authority and it hasn't happened.

I don't think there is any panic yet in the Djokovic camp.

I actually prefer the brand of tennis that Naomi Osaka is playing these days, as opposed to how she played at times when she was at her best.

She has always hit the ball so big and she has always been a one-two immediate strike player, but I feel like she is building points better and she is prepared to use her spin these days.

Normal service resumed after that quick exchange of breaks between Arthur Rinderknech and Novak Djokovic.

Naomi Osaka and Aryna Sabalenka have the highest overall performance rating of all the players in the women's draw, at 9.2.

American fourth seed Jessica Pegula is racing towards the finishing line on court two against Spain's Jessica Bouzas Maneiro.

Pegula, who has only gone beyond the third round at Wimbledon once in six previous attempts, broke Bouzas Maneiro in the opening game and then on a further two occasions to take the first set in just 20 minutes.
