Now it's the Novak Djokovic fans who are having their voices heard on Rod Laver Arena.

Their man avoids an awkward conclusion to his latest game to fight on in set two.

The Australian Open is the only Grand Slam event where Novak Djokovic has ever lost in the first round - and not since 2006.

There's a long way to go and a lot of hard work required by Dino Prizmic for the world number 178 to send Djokovic to an early exit here.

He must, you sense, begin by winning the second set. Djokovic sends a careless forehand long to bring the teenager to 40-30.

An ace brings Dino Prizmic to game point before Novak Djokovic can get on the board, with shouts from the crowd following as they hope to help the underdog over the line again here.

He faces no danger as he holds and puts the pressure on the world number one at the business end of the second set.

Dino Prizmic is playing with his upper left leg bandaged following that earlier medical timeout, but he has looked unaffected since that break after five games.

The teenager isn't allowed a point by Novak Djokovic as the top seed races to a love hold in the blink of an eye. But win this next game and he'll be one away from a first set on his Grand Slam debut.

Well Magda Linette returned to court after that medical timeout and managed three games but she lost them all to former world number one Caroline Wozniacki and has had to retire through injury.

She had heavy strapping on her left leg and was visibly struggling on Margaret Court Arena.

What a shame for the Polish 20th seed but Wozniacki advances to the second round where she will face Maria Timofeeva.

That is an excellent hold of serve by Dino Prizmic from 15-30 down.

An ace moves him 4-3 ahead of Novak Djokovic, who looked as though he was trying to psych himself up a bit during that game. The world number one is being given something to think about here.

The players exchange forehand winners, both are operating at a high level here and it's not all going Novak Djokovic's way as many would have expected.

The 18-year-old shakes a clenched fist in the direction of his team after battling his way to 30-30 by taking a key point.

No problem. Novak Djokovic serves out the game with an ace to draw level in the second set.

Novak Djokovic reaches game point on serve but pulls a forehand long to give Dino Prizmic hope. Signs of frustration there? Djokovic spins away after that miss and looks a bit annoyed at himself.

Dino Prizmic believes he's in the match here, you can see it in how he's playing in this second set. The Croatian is being more expressive, aware the crowd are keen to get behind him at every opportunity.

He takes the first point on the Djokovic serve.

Immediate response. That's how world number ones operate.

Dino Prizmic's moment is quickly spoiled as Novak Djokovic breaks back to 15.

A really important game for Dino Prizmic, who needs to back up that break here as he aims to level this match up.

But here comes Novak Djokovic.

A couple of unforced errors leave Prizmic facing two break points.

What it must be, to be 18 again!

Dino Prizmic is having the night of his life here. He's showing us everything he's got now and the exuberance of youth so much in evidence in that thrilling point, finished with the most stunning and brutal forehand crosscourt winner.

SHOT!

What a way for Dino Prizmic to seize his first break point. The teenager hits a ferocious cross-court forehand past Novak Djokovic to break the world number one to 15.

That was after Djokovic received a time violation before serving. Huge moment for the debutant!

Dino Prizmic wins a fifth point in a row as he executes an overhead at the net to take the opening point on the Djokovic serve.

A miss from Djokovic gives him 15-30... and now he'll have his first break points!

The free-hitting Croatian comes out on top in a superb point. Can he take these chances?

Since Novak Djokovic began working with Goran Ivanisevic, it feels like the serve has become a potent weapon.

I don't think Ivanisevic wants Djokovic to be faffing around in rallies he doesn't need to be part of because frankly, that's not exactly what Ivanisevic did in his career.

Polish 20th seed Magda Linette returned to court with strapping on her left leg after that medical timeout and looks to be hobbling around a little.

Caroline Wozniacki sees her opportunity, sending Linette scampering back and forth across the baseline.

The 2018 Australian Open champion closes out the opening set in ruthless fashion, securing her fourth game in a row in a largely dominant opener.

A love hold, sealed with an ace.

Dino Prizmic has found a bit of momentum here and the crowd are responding to the fight being shown by the qualifier.

Huge cheers as Dino Prizmic stands firm to win a 23-shot rally and take the opening point on serve. He's growing in confidence as we approach the hour mark.

But still there is no let-up from Novak Djokovic.

The world number one crashes down an overhead to respond with a hold to 15 of his own. Dino Prizmic just needs to make sure he keeps his nose in front for as long as possible in this set and hope an opportunity arrives from somewhere - however unlikely that may seem...
