Auger-Aliassime 6-6 (10-10) Djokovic*
Confident drive volley from Felix Auger-Aliassime and the ball is back in his court. Well, not literally. Yet.
But he has another set point on the Djokovic serve.
And again he cannot capitalise. Both players balloon forehands close to the line - but the Canadian's effort is long.

I'm glad Novak Djokovic is finding this funny. Everyone on Centre Court are on the edge of their seats as these two exchange set points.
Auger-Aliassime 6-6 (9-9) Djokovic
Big moment as Novak Djokovic survives a mid-rally slip and Auger-Aliassime hits a forehand long.
But then Djokovic misses a cross-court backhand just wide. Umpteenth set point to go begging.
Djokovic is laughing - but it might be fake laughter.

Felix Auger-Aliassime has done well there. He had a slip in the middle of the rally then he was on defence on the backhand side but he used the chip to get the ball deep and give himself time to recover.
It was a surprising unforced error on the forehand side for Novak Djokovic.
Auger-Aliassime 6-6 (8-8) Djokovic
A wild, wild forehand from Novak Djokovic, having had Felix Auger-Aliassime in all sorts of trouble in that rally.
Another set point for the Canadian - and an ace right on the line from the Serb! What a tie-break this is!
*Auger-Aliassime 6-6 (7-7) Djokovic
At the stage now where every other point will be set point.
Novak Djokovic gambles with a strong second serve and Auger-Aliassime returns it long.
And oh my goodness the Canadian just clips the line with a big forehand at set point down! Millimetres from losing the set!

That was a good strike from Felix Auger-Aliassime, but credit where credit is due because Novak Djokovic went big again on that second serve at 112mph.
Auger-Aliassime 6-6 (6-6) Djokovic*
What an ace, right in the corner of the service box. 124mph from Felix Auger-Aliassime.
The serve to follow is almost as good. Set point to the Canadian.
But a Djokovic serve out wide saves it. 6-6 at the changover.

Two quality serves from Felix Auger-Aliassime put the pressure right back on Novak Djokovic.
*Auger-Aliassime 6-6 (4-5) Djokovic
This is a tight tie-break.
Ebbing and flowing. But a cracking backhand down the line from Novak Djokovic keeps the seven-time champ's nose ahead.

One of the observations that we might make in the middle of all this is that Novak Djokovic seems to be moving alright.
If he is still in pain, it isn't quite as obvious as it was 20 minutes ago.

Novak Djokovic is starting to get agitated. He keeps looking up to the sky and waving his arms about.
I'm not sure if it's the light that's bothering him or if he's still struggling with that injury.

Maybe not - a weak backhand from the Canadian.
Serve has dominated all the first set - but not in this tie-break.
Novak Djokovic, by the way, seems to be moving a lot freer now after that earlier calf worry.
*Auger-Aliassime 6-6 (3-2) Djokovic
Auger-Aliassime outlasts Djokovic in a lengthy rally to dispatch a backhand volley at the net and recover that mini-break.
Oh and a stunning return turns the breaker right on its head! It's now the Canadian with the advantage after two points on the spin.

Novak Djokovic didn't get the luck that time with the net cord.
His shot gave Felix Auger-Aliassime the time to hit that forehand, move forward and knock off a nice backhand volley.
Auger-Aliassime 6-6 (1-2) Djokovic*
Is this where the nerves will hit?
Felix Auger-Aliassime sends a backhand well long to hand Novak Djokovic an early mini-break in the breaker.
Auger-Aliassime 6-6 Djokovic*
When the Auger-Aliassime first serve hits, it's almost unreturnable.
That 12th game was a bit hit and miss from the Canadian but he does enough to hold to 30 - aided by some big serves - to take us into a first-set tie-break.

This really is a tough period for Felix Auger-Aliassime because he has to stay so concentrated on his own end of the court and on his own game. He cannot afford to get drawn into Novak Djokovic's issues, such as wondering whether he is alright or whether he will carry on.
It is a hard thing to do.

These are worrying moments if you are the son, the wife or a fan of Novak Djokovic - but he holds on in this set!
*Auger-Aliassime 5-6 Djokovic
Fabulous backhand winner down the line from Auger-Aliassime to elicit a break point - but Novak Djokovic replies with an ace bang down the middle.
And a great serve out wide puts the Serb back ahead in this service game. Another ace follows!
What a hold that is.
