If Prizmic holds on to his serve here, it will irritate Djokovic...

A stunning sliced drop shot from Novak Djokovic.

A fourth match point.

Still, with three hours and 50 minutes on the clock and staring at match points, Prizmic doesn't know how to quit.

Three match points saved! Unbelievable, you really do want him to get a fifth set from this...

A superb floated drop shot from Dino Prizmic is met by an even better response from Novak Djokovic.

Three match points for the world number one to settle what has been a thorough opening test.

A couple of misses by Prizmic.

Djokovic is two points from the second round.

That is utterly businesslike from Novak Djokovic.

We've reached 11pm in Melbourne in the first night session of the 2024 Australian pen, and we still have Aryna Sabalenka's opening match to come. Whatever happens here, it's looking as though it could be a late finish.

Novak Djokovic is doing his best to get this wrapped up as quickly as possible and holds to love.

One game required. Can Dino Prizmic force him to serve it out and set up one final chance on the Djokovic serve? You feel he deserves that opportunity at the end of this excellent display.

Djokovic will be hoping he can rely on the serve that has become increasingly trustworthy in recent years.

Novak Djokovic nets a return and, from looking as though he was on the brink of defeat, Dino Prizmic reduces the gap to a single game from 4-0 down.

Three games in a row, when Djokovic was two games from victory. Will that play on the world number one's mind at all? Time to find out...

Can Dino Prizmic maintain this apparent return to his earlier levels?

The crowd are urging him on as he battles to 40-15 on serve but he needs to compose himself following a double fault.

Dino Prizmic offers an apology to Novak Djokovic as a backhand clips the net cord and drops over to deliver the break of serve.

An outstanding effort from the teenager. He's refusing to go away!

Not. So. Fast.

Dino Prizmic appears to have found a second wind! His reward is two break points. Surely not?!

Novak Djokovic has won his last 28 Australian Open matches, and he's just two games away from adding to that tally.

But Dino Prizmic is going to try and push him all the way. Over three and a half hours in against the world number one and a fine forehand winner gives him 15-30.

There's a little bit of Djokovic that's enjoying this - probably moreso now it's not as threatening...

Dino Prizmic is just about hanging in there, successive aces turning the game in his favour before a forehand winner ensures he make sit on to the board in this fourth set. The crowd let the teenager know they still appreciate his efforts.

Can Dino Prizmic at least slow Novak Djokovic's march to the second round?

He looks spent, in truth, but it's quite forgivable given the effort he has put into making this the spectacle it has been.

The Croat earns a quick point with an ace for 30-30 but Djokovic lands a forehand winner for break point.

Novak Djokovic will play the winner of the all-Australian match between Marc Polmans or Alexei Popyrin should he come through this test, as now looks inevitable.

An ace settles a straightforward hold to 15.

There's no stopping him now.

Novak Djokovic's quality is shining through now and it looks as though Dino Prizmic's race is run. Another break for the Serb, who is just three games from the second round.

Soothsayer Zac sitting pretty in their living room right now...
