Novak Djokovic is right about the roof situation. There is at least another 40 minutes of sunlight, you can play a set of tennis within 40 minutes!
I'm a bit perplexed when every night we have played until a certain point.

A huge cheer as Felix Auger-Aliassime wraps up the second set and levels this quarter-final.
It looks like the roof on Centre Court has just started to close, so there will be a bit of a break in play.
Novak Djokovic has packed up his bag and headed straight off court.

Interesting.
The roof is going to be closed and Novak Djokovic is not happy at all, he thinks the light is fine.
"We're an outdoor tournament," he argues.
It's not an argument he's going to win, though, and he trudges back to the locker room while the roof closes.

Would you believe it?!
On Auger-Aliassime's worse shot, which is the backhand, he finds the inside of the line.

Wow. Wow. Wow.
The Centre Court crowd are up on their feet, jumping up and down to applaud that Felix Auger-Aliassime winner. What a point.
Novak Djokovic stands with his hands on his hips, looking up to the sky in disbelief.

Well Felix Auger-Aliassime didn't go for the magic tweener that time and he gets himself out of a massive hole!

What a point!
An incredible rally, Novak Djokovic comes forward and plays a brilliant lob.

I said that Djokovic was acting so nonchalant and relaxed when he lost the previous game. He has lost concentration there.

Given Novak Djokovic's grass court record, and the physical demands being a little bit less on grass compared to the other surfaces, I would say this is his best opportunity for a 25th Grand Slam.
I do think there are less genuine contenders on grass as well.

Felix Auger-Aliassime keeps winning the first point on the Novak Djokovic serve. But, as yet, has not been able to ramp up the pressure from there.
He gets the perfect chance with a look at a second serve, runs around it but then booms the forehand long.
But hang on a minute, twice in a row Djokovic goes long and we have the first break point of the second set...

Unless my little umpire's scorecard is letting me down, Novak Djokovic has managed to win the first point just once in a Felix Auger-Aliassime service game so far.
It is monstrously hard to try to get it back - and certainly back on your terms. How impressive?

I hope Djokovic isn't so relaxed that he starts to lose focus and concentration.
