German's Eva Lys has been speaking to reporters following her win over Romania's Jaqueline Cristian, which made her the first lucky loser to reach the fourth round of the women's singles since 1988.

"Obviously I'm very, very happy to be making it to second week. I feel like second week was always such a dream for me," Lys said.

"I don't know when the realisation will kick in.

"It's definitely an amazing situation to be in, especially knowing that I was lucky loser.

"I think I found a picture of me sleeping the day I got in. I was just trying to spend the time at the venue, trying to do something because I didn't really know what to do with my time. I was just preparing for my flight the next day.

"It's an insane story, how fast it happened. It's been a couple of days. Those days have totally changed my life. So I'm definitely really thankful."

In her latest column with BBC Sport, Italian fourth seed Jasmine Paolini discusses using her height to her advantage...

I've heard that one of the most popular things which comes up next to my name in internet searches is 'height'.

That's because I'm 5ft 4in. It's pretty unique because most of the players on the WTA Tour at the moment are a lot taller.

I heard that the average height of the players currently in the top 10 is about 5ft 10in. I'm also told that I am the smallest player in the top 20.

But it's not something I worry about - I just try to play my tennis and concentrate on my game.

Being smaller means I have different weapons to a taller player. We work with what we have, you know!

I move pretty well on court and people generally say that is my biggest strength.

Ever since I was a child I have been quick and nimble.

I remember being at the tennis club when I was young and doing some training sessions where we did sprinting drills. I was one of the fastest then.

More from Emma Raducanu, who was talking to Russell Fuller:

On not quite being ready for the Australian Open:

"I don’t think with the back or anything, I have any excuses for the match. I just think in terms of preparation it just wasn’t the best for the Australian Open in general.

"I think that happened because of the circumstances and we did the best job we could in managing the training loads and getting up to speed.

"Today against a top player – its just not enough."

On moving on?

"I don’t think it necessarily does affect my confidence – I know exactly what happened out there. I’m pretty clear on that and I don’t think I am any worse of a tennis player and probably better in a number of aspect than I’ve played here in the past.

"It’s just when certain things don’t fire in a match, it’s easy for the scoreline to look pretty brutal.

"With certain things in my game I need to work on and take today as feedback."

On her schedule:

"It’s extremely busy. Right now I am signed up to play in Singapore and the Middle East but a lot depends on which tournaments I can get into as well with my ranking."

We're not far away from defending champion Jannik Sinner taking to court as heopens the night session on Rod Laver Arena. He takes on American Marcus Giron from 08:00 GMT.

After that, Maddison Keys takes on Danielle Collins in an all-American clash.

On Margaret Court Arena, Ukrainian 28th seed Elina Svitolina faces Italian fourth seed Jasmine Paolini before Danish 13th seed Holger Rune takes to court against Serbia's Miomir Kecmanovic.

At John Cain Arena, American 21st seed Ben Shelton has just taken the first set against 16th seed Lorenzo Musetti.

If your serve isn't firing it changes everything.

If you don't get first serves or accuracy is off then suddenly, you have Iga Swiatek who is so intense and she was stamping authority from the word go. Big returns, crushing blows from the back of the court and she never looked like she would take her foot off accelerator.

Emma Raducanu can go away and analyse and work on it on the practice courts and that's what she'll do but nothing can replicate going out there and competing. So she has to keep playing on the Tour but her body has always let her down and stopped her getting momentum.

Emma Raducanu spoke to BBC Sport tennis correspondent Russell Fuller after her third-round loss to Iga Swiatek:

"It was a difficult match. I think Iga played really well. She’s a top player and when you play someone like that you also need to bring a high level and I don’t think I was able to do that today.

"It was a little bit of both and I need to just reflect and take confidence from the first two rounds and just keep moving.

"I think I just found it difficult to get going with certain things in my game not necessarily functioning. I think that seeps into the rest of it and I just felt it trickling into everything – my groundstrokes, my serve and return games as well.

"I found it really difficult to get started and we know how much of a big shot the serve is, and I lost a lot of confidence in the rest of my game because of that.

"I’ve been managing [my back] for the last few weeks but three weeks ago I was doing pool rehab in Auckland unable to even practice. I only started hitting when I got here 18 days ago so I guess with the doubts going into this tournament I have to just take the positives and be grateful I was able to compete."

American eighth seed Emma Navarro joked she "can't resist" going the distance in her matches after winning her third consecutive three-set encounter at Melbourne Park.

The 23-year-old beat former Wimbledon and US Open finalist Ons Jabeur 6-4 3-6 6-4 to reach the fourth round.

Since the start of 2024, Navarro has played 32 matches that have gone the full three sets, winning 23 of them.

"I love three sets. I love tennis so much I can't resist, I gotta play three sets," Navarro said.

Navarro is the daughter of billionaire businessman Ben Navarro, founder of the Sherman Financial Group, and credited her dad for her stamina, saying he would take her and her siblings on six-hour bike rides as youngsters.

"We made up a term: biking and crying," Navarro said.

"I learned a lot of toughness growing up. A lot of thanks goes to him."

Feels harsh, actually.

Germany's Eva Lys made history at the Australian Open as she became the first women's singles lucky loser to reach the fourth round of the Melbourne Grand Slam since 1988.

The 23-year-old, ranked 128th in the world, came from a set down to beat Romania's Jaqueline Cristian 4-6 6-3 6-3.

Lys' reward is a meeting with Polish second seed and five-time Grand Slam champion Iga Swiatek.

Lys had her bags packed and a flight booked after losing in the final round of qualifying and was given 10 minutes notice before her first-round match that she had been admitted into the main draw.

At the time, she was lying on a physio table receiving treatment and worried about the lack of preparation but has since recorded wins against Australian Kimberly Birrell, France's Varvara Gracheva and now world number 82 Cristian.

Lys will now take home at least A$420,000 (£210,342) for reaching the fourth round in Melbourne. A marked difference on the A$50,000 (£25,300) she thought she would be going home with after going out in the third qualifying round.

Elena Rybakina says she will need some "magic" if she is to go deep at the Australian Open after struggling with a back problem in her third-round win.

Sixth seed Rybakina, runner-up at Melbourne Park two years ago, beat Ukraine's Dayana Yastremska 6-3 6-4 but needed a medical timeout after just three games.

The 25-year-old Kazakh was visibly struggling to move and needed seven match points to close out victory.

Asked afterwards if her back was OK, Rybakina replied: "Not really. I will see my physio and hopefully he does some magic.

"Honestly, I didn't know how it was going to go because it came all of a sudden."

Rybakina will face either Danielle Collins or Madison Keys, who play later on Saturday, in the fourth round on Monday.

An absolutely brilliant match we've had this morning as French veteran Gael Monfils stunned fourth seed Taylor Fritz to become the second-oldest man ever to make the last 16 at Melbourne Park after Roger Federer.

The 38-year-old came through 3-6 7-5 7-6 (7-1) 6-4 to reach the fourth round for a sixth time in his 19th Australian Open.

It was Monfils' first Grand Slam win against a top-five player since 2008.

That was on Margaret Court Arena, where Monfils' wife Elina Svitolina will take on Jasmine Paolini shortly and the Frenchman joked he had "warmed it up" for her.

He even showed off some dance moves following his win.

Here's how things are shaping up on the two main courts at Melbourne Park for the night session:

Rod Laver Arena

• Jannik Sinner (Ita) v Marcus Giron (US) - from 08:00 GMT
• Madison Keys (US) v Danielle Collins (US)

Margaret Court Arena

• Elina Svitolina (Ukr) v Jasmine Paolini (Ita) - from 08:00 GMT
• Miomir Kecmanovic (Ser) v Holger Rune (Den)

So, the numbers are dwindling...

As we know Emma Raducanu was thrashed by second seed Iga Swiatek.

Elsewhere, American eighth seed Emma Navarro beat Tunisian Ons Jabeur 6-4 3-6 6-4 and sixth seed Elena Rybakina progressed ahead of Ukrainian 32nd seed Dayana Yastremska.

And German lucky loser Eva Lys' dream Australian Open run goes on after she reached the fourth round with a 4-6 6-3 6-3 victory over Romania's Jaqueline Cristian.

In the men's draw, home favourite Alex de Minaur has just come from a set down to beat Argentine Francisco Cerundolo in an absolutely gruelling match while 38-year-old Frenchman Gael Monfils stunned American fourth seed Taylor Fritz earlier on.

Britain's Jack Draper fought through his third successive five-set epic at the Australian Open to tee up a blockbuster meeting with Spanish superstar Carlos Alcaraz in the fourth round.

Draper, seeded 15th, won 6-4 2-6 5-7 7-6 (7-5) 7-6 (10-8) against home hope Aleksandar Vukic in another late-night thriller on day six.

The British number one had already quelled a partisan Australian crowd with a comeback win over Thanasi Kokkinakis on Wednesday - and showed more of his monster mentality two days later.

"I'm very, very proud of my efforts from the physical part of things," said Draper, a 2024 US Open semi-finalist who is playing his first tournament of the season after a hip injury.

"I'm obviously not feeling incredibly fresh right now, but I'll recover again. I'll do my best to go again for another one."

He is now the last Brit standing in both the men's and women's draws after Emma Raducanu's exit earlier today.

While Emma Raducanu and Iga Swiatek both won Grand Slam titles as teenagers, their careers have followed very different paths since.

The Briton, who famously won the 2021 US Open title as an 18-year-old qualifier, initially struggled with the spotlight placed on her afterwards.

A series of injuries culminated in wrist and ankle surgeries in 2023, with Raducanu dropping out of the world's top 300 and still finding her way back.

In contrast, Swiatek continued to thrive after winning the 2020 French Open.

Three more victories on the clay courts at Roland Garros have been supplemented by a US Open triumph in 2022.

Swiatek had won all three of their previous professional meetings - and the gulf between the pair remains wide.

Those night owls among you may have stayed up to see Emma Raducanu suffer an absolute thrashing at the hands of Polish second seed Iga Swiatek.

Not quite a double bagel, but a chastening 6-1 6-0 loss for the Brit on Rod Laver Arena.

The world number 61 lost serve five times in a defeat which took just one hour and 10 minutes.

It's getting towards crunch time at the Australian Open as players in the men's and women's draws aim to reach the fourth round and therefore the second week in Melbourne.

The business end, some might say.

Let's get into it on day seven at Melbourne Park.

Well, that wasn't how Emma Raducanu planned it.

The fact that Iga Swiatek was out of this world might provide a small crumb of solace.

Thanks for staying up and following along (presuming most of you are in the UK) even if the result wasn't as you hoped either.

Make sure you keep across the BBC Sport website over the rest of the Australian Open.

Ta-ra!

With Raducanu already back in the locker room, Swiatek sticks around to have a word with the crowd.

"I just enjoyed playing," she says. Quite.

She adds: "I felt really confident and at the end I could push for even more.

"Converting all these break points was really important and I'm pleased with that performance."

That, my friends, is what we call a tough day at the office.

Emma Raducanu solemnly shakes hands with her opponent before making a sharp exit.

A bitter pill to swallow.

Losing one and love is the joint worst defeat of Raducanu's professional career.
