My goodness - what a last few points from Jack Draper!
It has really been the last couple of games. His shot making and his come up with the drop shot out of nowhere is not easy. He completely changed the pace and the spin.
And to hit that delicate of a shot at that moment!
Djokovic 6-1 6-4 5-3 Machac*
Another ace from Novak Djokovic to take the hold as he creeps closer to the fourth round.
The Serb will want to close this out and break Tomas Machac to take the match.

Nothing like a running forehand around the net post to leave the crowd gobsmacked.
Nor an explosive winner from your baseline to the other.
Jack Draper is putting together a highlights reel.
*Draper 6-4 0-0 Vukic
How about that?! Jack Draper puffs out his cheeks and swaggers to his chair after lifting a sensational drop shot cross-court and well beyond Aleksandar Vukic.
After a slow start, the British number one is a set to the good.
Draper 5-4 Vukic*
Sublime from the British number one. It looks like Aleksandar Vukic had sent a cross-court winner past Jack Draper, but the 15th seed somehow gets there and pushes a bullet forehand down the line.
And all of a sudden, he's got himself two set points.
*Djokovic 6-1 6-4 4-3 Machac
Tomas Machac saves break point with his first ace of the third set then Novak Djokovic slams into the net to give the Czech game point.

Djokovic 6-1 6-4 4-2 Machac*
Well Tomas Machac has been unable to make inroads on the Novak Djokovic serve and now he's struggling to keep hold of his own.
Another lengthy rally from the baseline results in Djokovic earning a break point.
Djokovic 6-1 6-4 4-2 Machac*
No problems for Novak Djokovic as he takes the hold to love.

The pressure tells on Aleksandar Vukic and there's a collective groan on Margaret Court as their Australian home hope double faults.

Jack Draper has started out just a little nervously, as you can understand with it being a big opportunity for both players.
But the higher seed is going to feel a little more of those nerves, and that is the challenge for Draper right now.
Draper 3-4 Vukic*
A big chance for Jack Draper, who has got himself three chances to break back as Aleksandar Vukic fires long.

You could tell Jack Draper was pleased to shut a few naysayers up after beating Thanasi Kokkinakis on Wednesday.
The young Brit developed a tag as the 'guy who is always injured' and there have been question marks over his fitness.
But he has come through back-to-back five-setters here in Melbourne.
Draper had never played two Grand Slam matches in a row which went all the way.
What makes his grit and durability more impressive is that his pre-season was disrupted by that hip injury.
Draper 3-4 Vukic*
Shotttt. Jack Draper is sent out wide and is forced to sweep his forehand around the net post and in. Even Aleksander Vukic has to applaud that.
The British number one moves Vukic side-to-side until the Australian leaves the rest of the court empty for Draper to land into.
*Djokovic 6-1 6-4 3-2 Machac
Tomas Machac survives to take the hold and keep it to just the one break of serve.
He's going to have to make his move very soon.
Djokovic 6-1 6-4 3-1 Machac*
A brilliant forehand from Thomas Machac saves break point.
Novak Djokovic can't believe that it stayed inside the lines but it was very close.
There's been a bit of disgruntlement from Djokovic throughout this match because of people in the crowd shouting out and once again the Serb asks the umpire to tell them to be quiet.
*Draper 2-4 Vukic
After winning all 10 points on his first serve, suddenly Aleksandar Vukic falters with a double fault pulling Jack Draper level at 30-30.
That's as far as the 15th seed will get as Vukic recovers and a smash volley at the net wins the game.
Djokovic 6-1 6-4 3-1 Machac*
Novak Djokovic gets out to 0-30 on the Tomas Machac serve before the Czech draws back level with a miraculous forehand down the line that clips the net but stays in.
He overhits the forehand at 30-30 to hand Djokovic a break point.
Draper 2-3 Vukic*
Jack Draper is working his way into this and he wraps up a comfortable service game with an ace that kisses the line.
