You feel like Pliskova is a bit scared to go to the Barty backhand now and get that slice, and having to bend the legs.

British wheelchair doubles pair Alfie Hewett and Gordon Reid are under way in their final against Dutchman Tom Egberink and Belgian Joachim Gerard.

And they've made the perfect start on court three, breaking serve in the opening game.

You can follow that one at the top of this page.

Karolina Pliskova needs to be more proactive, get ahead in points.

That serve needs to pick up some steam - to me it's a good 10 miles per hour slower than normal.

She's not out of this yet though, she's got to tell herself that.

She has to keep the unforced errors to a minimum, at least make Barty beat her.

That score of 30-30 quickly becomes 30-40 and turns into another break chance for the world number one. Barty takes it after another error from her opponent. Only 20 minutes on the clock and she will now serve for the first set...

For the first time, maybe Barty maybe feeling the nerves, as Pliskova retrieves one of the breaks.

Pliskova grimaces as she clunks a forehand into the net for 0-15. The sort of face we'd pull when the local shop has ran out of milk.

The Czech turns the game into her favour at 30-15, but then stops as she is pulled wide by Barty and left stranded by a smash which almost dents the lush grass. 30-30...

Martina Navratilova and Billie Jean King know a thing or two about winning major titles. They chew the fat about the opening to this match at the changeover.

The tennis royalty are sat behind the British royalty. No idea if Wills and Kate are talking tactics.

Barty hasn't made a mistake so far but a couple of freebies could go a long way for Pliskova.

The first 14 points of the match went in favour of the Aussie. But now here's a chance for Pliskova.

A couple of unforced errors from Barty make it 0-30 before the top seed challenges a call and gets it right. Replay the point.

Pliskova wins that too. Three break points for the Czech. She takes the first! Barty slaps another forehand into the net.

Pliskova will take anything she can get. But that was a gimme from the Aussie.

Lee Fergusson: Wow what a start from Barty

Quite a few Aussie football, cricket and rugby tops in the Centre Court crowd, as well as some yellow and green wigs.

The fans wearing them are happy and there is the first muttering of "golden set?"... a bit early maybe but Barty is already halfway there.

One is saved when Barty slaps into the net. What about the second? Oh no! A double fault from Pliskova. This is a tough watch for the neutrals on Centre.

A match-winning cheer erupts on Centre as Pliskova wins her first point.

And another! Partly encouragement for the Czech and partly relief that they might get a bit more tennis for their money.

Ominously, Barty moves 0-30 in front with another forehand winner. Pliskova struggling here. She needs a point, quick. She gets it! A huge cheer as the Czech finally gets on the board.

But then another backhand error makes it 15-40 and Barty has more break points...

Let's hope a good swig of water at the changeover helps melt Pliskova's brain freeze. The Centre Court crowd are doing their best to help her, but another lame return hits the net for 0-15.

At the moment Pliskova is totally frozen.

This is a complete disaster so far. She hasn't even won a point.

It feels like she's not moving at all. She needs to put out of her head what just happened. It's exactly what you don't want to happen.

Pliskova is barely moving out there. She looks riddled with tension.

Barty doesn't have the power of Pliskova's serving, but instead she has the placement. She's painting the lines like the groundstaff who were saw earlier on Centre Court.

Another hold to love for the Aussie. Pliskova looks frozen at the moment. She's not won a single point yet...

Those legs aren't moving yet at all.

She needs to get points on the board.

We've talked about the Pliskova serve but it's barely into first gear. The Czech is missing the power that she is famed for, allowing Barty to seize control with a pair of blistering forehand winners.

A weak backhand into the net brings up three break points for Barty. Uh oh.

And she takes the first with a backhand winner.

Definition of a nightmare start for the Czech.
