Australian Open 2024 results: Novak Djokovic beats qualifier Dino Prizmic in his longest first-round match

Djokovic, who could achieve a record 25th Grand Slam singles title this month, later said he had felt “under the weather”.

While the Serb will face Alexei Popyrin or Marc Polmans in the second round, Prizmic – crowned French Open boys’ champion last year – has a bright future ahead on the evidence of his breakthrough performance on Rod Laver Arena.

Sunday’s match surpassed Djokovic’s previous longest in the first round of a major, which was a three-hour-57-minute encounter against Gael Monfils at the US Open in 2005.

Few could have anticipated the absorbing tussle which would develop after Djokovic took a straightforward first set.

But Prizmic hinted at what was to come when he broke Djokovic for the first time for a 3-1 lead in the second, before holding his nerve in the tie-break with his fourth set point.

That set up a rollercoaster third set, which Djokovic claimed by winning four successive games – but only after Prizmic had battled back with a double break from 2-0 down.

And even as the result began to appear a formality in the fourth set when Djokovic continued his run of games for a 4-0 lead, his teenage opponent refused to go quietly, breaking back before saving four match points in the ninth game to force the top seed to serve out victory.

“He deserves all the applause. He is an amazing player, he handled himself incredibly well on the court. This is his moment,” Djokovic said.

“It could easily have been his match as well. He showed great mentality and resilience.

“I certainly want to be in his corner. So hopefully he will invite me, because he will make some big things in his career that’s for sure.”
