What a spectacular Wimbledon singles competition so far for British 22-year-old Harriet Dart.

The London-based player has managed to go two stages further than she did on her debut last year.

After seeing off Christina McHale and Beatriz Haddad Maia she now faces an Australian by the name of Ashleigh Barty, who happens to be the French Open champion and world number one.

We get under way on Centre Court shortly.

It's a very, very busy day six at Wimbledon.

And it's another huge day for the remaining Brits, as Johanna Konta, Dan Evans and Harriet Dart all take to the grass.

Dart is first up, and she faces a huge challenge against world number one Ashleigh Barty on Centre Court.

Konta faces American Sloane Stephens in the second match on Court One, after Serena Williams' match against Julia Gorges.

Then, Evans completes the day's Court One schedule, taking on Joao Sousa for a place in the fourth round.

The great and good of the sporting world are taking their seats in the Royal Box on Centre Court, the list includes: Joe Root, Sir Mo Farah, David Haye, Carl Froch, Ann Jones, James Anderson, Gareth Southgate, Rod Laver...

We're going to label today's jam-packed schedule 'Super Saturday', with a whole host of tennis royalty in action and plenty of brilliant Brits to boot.

But we want to know how you're following the action, with picture evidence...

American world number 55 Alison Riske has hit back against 13th seed Belinda Bencic on court 12.

We are all square.

France's Lucas Pouille, 25, faces the unenviable task of finding a way past eight-time champion Roger Federer if he is to reach the second week at Wimbledon.

Can he produce a shock on Saturday?

A "See you soon on Centre Court" message accompanied by some telling emojis suggests he's relishing the opportunity.

They are third up on Centre Court so an early evening encounter in store...

We're gearing up for some Murray Mania...

Yes, Andy is due on court two next - although not before 13:00 BST - as he continues his men's doubles campaign alongside France's Pierre-Hugues Herbert.

They meet Croatian sixth seeds Nikola Mektic and Franko Skugor.

The Scot will be hoping he can come through this second-round meeting quickly, with his mixed doubles match with Serena Williams due to be played later today.

Kei! Kei! Kei!

Kei Nishikori, possibly one of the most unlucky of the top players over the past few years, is two sets to the good against American Steve Johnson.

A gentle reminder that the Japanese eighth seed trailed 3-0 in the first set.

There are a lot of famous sporting stars sitting in the Royal Box today, including current and former cricketers Andrew Strauss, Jimmy Anderson, Eoin Morgan, Joe Root, Jonny Bairstow and Stuart Broad, boxers David Haye and Carl Froch, England men's manager Gareth Southgate and midfielder Eric Dier.

Plus there is England netball captain Ama Agbeze, rugby players Jonny May and Maro Itoje, six-time Olympic cycling champion Sir Chris Hoy, and IAAF president Lord Coe.

But it was perhaps this guy, four-time Olympic champion Sir Mo Farah, who attracted the most attention outside the entrance to the Royal Box.

There's going to be quite a few ladies in the top half of this draw that will have seen the way Petra Kvitova played this match today and they will be paying attention.

A tremendous performance, excellent movement, terrific serving, just too many weapons for her opponent today.

She kept the unforced errors to a minimum, she used the court well. She came in to Wimbledon without too many matches under her belt but it didn't look like that today.

The Kvitova serve is popping like a toddler on bubble wrap.

She is a serious proposition for anyone in this draw.

Mayday for Magda!

Linette is 40-0 up and looks set to at least keep within a break of Petra Kvitova.

But she falters within sight of the finishline. Petra Kvitova pounces and the game is lost.

Kvitova serves for the set next.

The frustration for Linette is that she hasn't played that badly.

But she's being swiped aside by Kvitova.

It's tough to think about slice, drop shots and angles when you've got rockets flying at you.

But Petra Kvitova's serve arms is turning over at the pace of a peak Shoaib Akhtar.

She looks like she has it locked down as tight as Fort Knox.

Magda Linette needs to come up with a Goldfinger-style plan and sharpish if she is to extend this match at least to three sets.

The best service game of the match so far from Pole Magda Linette as she holds to love.
