Some well worked points there by Mirra Andreeva and she's able to finish them off by firing into an empty court, with Elina Svitolina left stranded on the other side.

But Svitolina gets her own back with a lovely backhand winner down the line to bring up another break point.

The biggest cheer so far. And it's not for Mirra Andreeva or Elina Svitolina.

After missing her first serve, Andreeva whacks a stray ball away and it's brilliantly caught one-handed by a ball kid.

The crowd loved that.

Mirra Andreeva makes a run to the net and Elina Svitolina isn't able to squeeze in a pass, so there's a chance for the 18-year-old to get this first set back on serve.

And she does just that as Svitolina lofts a backhand wide.

Elina Svitolina holds her hands up apologetically after a lucky net cord goes her way and catches Mirra Andreeva off guard.

The pair exchange unforced errors before Svitolina hammers down an ace, but we go to deuce after the Ukraine 12th seed slices into the net.

Mirra Andreeva saves the first break point with an ace, but she follows that up with a long forehand - despite having the option to smash it down at the net.

Advantage, Svitolina.

Oh dear. An untimely double fault from Mirra Andreeva gives Elina Svitolina two break points.

Elina Svitolina has definitely got her game face on, no smiles at all and total focus and concentration.

She looks physically very different at the moment, I think she might be the fittest I've ever seen her.

Mirra Andreeva has never reached the quarter-finals in Melbourne before.

She lost in the fourth round in 2024 and 2025, so she will be hoping that it's not three fourth-round defeats in a row in Australia.

Elina Svitolina gets another hold over the line as the Russian teenager finds the net.

Elina Svitolina swats a forehand wide and gifts Mirra Andreeva the hold. On we go...

Two poor misses from Mirra Andreeva open the door for Elina Svitolina, but the teenager claws her way back with a couple of powerful winners.

An overcooked forehand from the teenager brings us to deuce.

Elina Svitolina is somebody who has really worked on that forehand side, she is such a beautiful ball striker and everything she brings to the court is more about physicality and athletic ability.

She's added pace and power particularly on that forehand side.

Elina Svitolina is taken to deuce on her first service game, but she pulls through safely to get on the board and settle any early nerves.

There was no handshake between Mirra Andreeva and Elina Svitolina before the match, and there's unlikely to be one after the match.

Ukraine's Svitolina has been outspoken about her home nation's struggles since Russia invaded Ukraine in February 2022 and she does not shake Russian opponent's hands before or after matches.

We've got youth and experience up against each other, so that's always interesting.

We've got Mirra Andreeva who is the higher ranked youth player, who has more pressure on her shoulders.

The way that she plays her tennis is like a chess player, she's so intriguing, but she's also added power and aggression.

She can come forward, she can volley, but of course she's up against one of the greatest competitors and fighters.

It has got all the ingredients for a really good clash.

Elina Svitolina and Mirra Andreeva have only met once before, at last year's Indian Wells.

The Russian teenager triumphed 7-5 6-3 in the quarter-finals in California before going on to win the tournament.

The gods have smiled on Jannik Sinner by closing the roof and the gods are maybe smiling on Novak Djokovic with that one-round break to be able to rejuvenate and get ready for week two.

Before we get into the build up for Elina Svitolina v Mirra Andreeva, let's just quickly react to the news of Jakub Mensik's withdrawal.

It means 24-time major winner Novak Djokovic gets a free passage to the quarter-finals.

He will be facing either Taylor Fritz or Lorenzo Musetti in the last eight.

We've got one more match on Rod Laver Arena coming up.

Ukraine's Elina Svitolina, the 12th seed, will be taking on Russian eighth seed Mirra Andreeva very shortly.

The pair have just arrived on court.

More from Alex de Minaur on his plans for his days off: "I'm going to do my best to sleep in, get a good coffee to start the day. As far as preparation, I have hit enough tennis balls recently so I'm not going to need to do much. A nice easy session, ultimately just relax a little bit and enjoy my time in Melbourne and get ready for an absolute battle in a couple of days time."

Alex de Minaur, speaking after his straight-set victory over Alexander Bublik: "I knew what I was in for today. Bublik is a hell of a player, he has so much firepower. I lost to him the last couple of times so I made sure I was ready to go from the first point to the last. I was locked in and it was all about neutralising his big groundstrokes and doing my best to get him on the move. It all worked perfectly so I'm super happy."

On getting revenge for losses against Bublik: "I was definitely thinking about the last two matches I played him. He is super dangerous, he can hit winners off anything and take rhythm out of the match and make it as scrappy as possible. I had to be locked in from the first point to the last. A huge mental effort. Onto the quarters so job done.

"The last two matches I have hit the ball extremely well. So I'm super pleased with my level, I am excited for the next one. That's going to be a big one, right? I am going to have to come out all guns blazing and I'm excited for a battle against Carlitos [Carlos Alcaraz]."
