This is not the Djokovic we are used to watching, he has double faulted already. We have been waiting for him to look human and so far he has been.
We certainly weren't expecting to see this.
Alexandrova 6-6 (3-0) Bencic
Ekaterina Alexandrova has won all three points so far and she has two serves of her own to come...

Every Novak Djokovic double-fault is greeted by surprise and hushed chatter among the Centre Court crowd.
While they will have hoped for a competitive match between the sixth and 11th seeds, few would have expected the seven-time champion to look quite so out-of-sorts here on a stage that has become his second home over the years.
Alex de Minaur, on the other hand, would have been dreaming of a start like this last night.

Some great defence by Alex De Minaur. Djokovic seems to be more affected by the conditions at the moment.
If De Minaur is going to take on this game today, he has got to take chances.
Alexandrova 6-5 Bencic*
For the first time in this match, Ekaterina Alexandrova is ahead.
What a turnaround.
The pressure's on Belinda Bencic now, with the Swiss about to serve to stay in this first set.
De Minaur 3-1 Djokovic*
Comfortable hold for Alex de Minaur.
It's breezy on Centre Court and so far the Australian is coping better with the conditions than his 38-year-old opponent.
Novak Djokovic sends a bunted forehand long to end the game, the wind took that and it just drifted over the baseline.

That wind we had at the start of this match has settled, and so has Ekaterina Alexandrova as she levels up matters. How quickly things can change in tennis and the momentum now is with Alexandrova.

Novak Djokovic has been giving little away so far, having immediately been put under pressure on Centre Court, and there was still no reaction when he lifted over a delightful drop shot which received a lot of love from the crowd.
There has been the odd glance to the sky and puff of the cheeks from the former world number one as Alex de Minaur's solid start continues.
Djokovic has won nine of his 10 sets so far at the All England Club but already this is shaping up to be a stern test.
*Alexandrova 5-5 Bencic
Well, well, well!
Since going 1-4 down, Ekaterina Alexandrova has just been firing from the hip.
Her new-found aggression is paying off, too, with the Russian clawing back Belinda Bencic's double break lead.
We're back on serve.
*De Minaur 2-1 Djokovic
Novak Djokovic is on the board.
A swift service game see him hold to 15. Now to try and get that break back.
*Cilic 4-6 4-6 7-6 (7-4) 1-2 Cobolli
Image source, Getty ImagesMarin Cilic clinches the third set to stay in the match!
It looked like his dream run was coming to an end on court two, after 22nd seed Flavio Cobolli opened up an early two-set advantage, but the 36-year-old has just taken the third-set tie-break 7-4.
Cobolli will be kicking himself though, after practically handing the Croat the set with a poorly timed double fault. Cilic will be feeling relieved on the other hand, after missing three previous opportunities to see out the set and keep himself in the match.
Which way will this one go? Well, they are still on serve in the fourth set.
De Minaur 2-0 Djokovic*

It is always hard to build a strategy to take on Novak Djokovic. There are no real weaknesses in any part of his game.
De Minaur is doing a good job at controlling his shots considering how windy it is at the moment. He is playing with content and biding his time when he needs to. He has got to push Djokovic round the court, which is easier said than done.

The Aussie has started rather nervously in his first few games but this is a totally different De Minaur out there today.
It is always hard when you come in as the underdog but he is looking good.
