Women's world number four Jasmine Paolini will get her Australian Open campaign under way shortly over on Margaret Court Arena, where she comes up against China's Wei Sijia.

The Italian, 29, reached her first major finals last year at the French Open and Wimbledon to reach her career-high ranking.

She also produced her best run at the Australian Open in 2024, reaching the fourth round after failing to win in any of her four previous main draw appearances.

On the other side of the net is 21-year-old debutant Wei, who is ranked 117 in the world and is hoping to achieve her first win over a top-10 player.

Britain's Cameron Norrie says he could "barely practise" before his Australian Open defeat by Matteo Berrettini because of sickness.

Norrie, 29, lost 6-7 (4-7) 6-4 6-1 6-3 to thebig-serving Italian in the first round on Tuesday.

The British number two said he became ill in Auckland, where he played a warm-up tournament before heading to Melbourne.

"It was not the best preparation," said Norrie, who reached the fourth round last year.

"I just hit the wall after an hour and a bit. I was not able to stay sharp on the court.

"It is a bit disappointing but it is what it is. Most importantly I need to get my health back to 100%."

Emma Raducanu overcame second-serve wobbles to start her 2025 season with a scrappy win in the Australian Open first round.

The British number two, whose preparations were disrupted by a back injury, won 7-6 (7-4) 7-6 (7-2) against Russian 26th seed Ekaterina Alexandrova.

While hitting well from the baseline, Raducanu was hampered by double faults and lost serve six times.

The 2021 US Open champion hit 15 double faults, including a particularly-deflating one on break point when she looked to close out a straight-set victory from a 5-4 30-0 lead.

However, the way she regrouped and dominated another tie-break to get over the line was impressive.

The 22-year-old had a sheepish grin as she walked to the net and said afterwards: "I think my serve had a mind of its own."

Here is what men's fifth seed Daniil Medvedev had to say following his five-set win over wildcard Kasidit Samrej at the Australian Open:

"I know that I play better when I play more tennis. So I was like, 'why play one hour 30', maybe I needed to play three hours minimum to feel my shots better, to have a good sensation.

"In the second and third set I couldn't touch the ball, I didn't know what to do.

"I watched his [Kasidit Samrej's]matches and I didn't see this level, so I was surprised.

"If he plays like this every match, his life can be good. Money, girls, casino, whatever.

"I wish he could play like this every match. You need to be consistent to make it in tennis and I wish this for him."

On the birth of his second child and not playing any matches in the lead-up to the Australian Open, he said:

"I am probably never going to play a lead-up tournament now unless they move it, being with my kids.

"It only gives me good energy. In the last year I probably would have lost this match but new year, new energy and I'm happy to win this match."

Medvedev has pretty much just played three matches in one. I think that is probably as much training as he could get under his belt going into the second round.

More than anything, it was the conditions and the fact that he arrived so late into Melbourne that he had to deal with. Daniil relies on feeling the court and feeling the ball, but he really had no time to do that.

But that takes nothing away from his opponent, Kasidit Samrej played really well. I hope he takes confidence from this match going into the rest of 2025.

Daniil Medvedev celebrates after delivering what he believes to be the knockout blow, repeatedly pointing to the ground as he makes eye contact with someone in the stands.

A second break of serve for the fifth seed in this fifth set leaves him serving for the match after more than three hours against Kasidit Samrej.

Daniil Medvedev holds serve once more to edge closer to victory over Kasidit Samrej, who is definitely feeling it physically now.

But that should be no surprise. What an effort by the world number 418, who is being cheered on all the way by the crowd inside Rod Laver Arena.

The fact that Kasidit Samrej said he didn't know if he would get another chance to play at another Slam is keeping him in this match.

I hope he changes that attitude because he has a wonderful game. He has great timing and he doesn't use up too much energy with his shots.

It's just the overwhelming factors that are causing him to cramp today.

We're waiting to see what time Katie Boulter will get on court to begin her campaign.

The British number one is scheduled to contest the final match on Kia Arena, against Canada's Rebecca Marino.

But the match before that, between Italian pair Lorenzo Musetti and Matteo Arnaldi, is still in the early stages after Arnaldi levelled the match against the 16th seed at one set all.

All credit to Kasidit Samrej, who has been receiving physio treatment to his left thigh during the latter stages of this contest as he attempts to go all the way against Daniil Medvedev.

The 23-year-old manages to hold serve to ensure he remains within reach of Medvedev in the final set.

He just needs to keep the pressure on the Russian fifth seed for as long as possible and hope Medvedev suffers another dip - but that isn't happening for now as Medvedev holds to restore his two-game advantage.

After dominating the fourth set to force the decider, Daniil Medvedev has maintained his late momentum by breaking Thailand's world number 418 Kasidit Samrej at the start of the fifth.

The Russian fifth seed misses a first break point at 30-40 but keeps the pressure on his opponent, making his Slam debut, and gets his reward.

It's been a real struggle, but there are signs that Medvedev has a lot more left in the tank than the 23-year-old Samrej as he consolidates his advantage with a comfortable hold.

Daniil Medvedev was not stopping until that racquet was well and truly battered beyond repair.

Obliterating a racquet against netting alone is kind of impressive even for Medvedev, who shall we say is not particularly one to hide his on-court emotions.

Could there be a huge shock on the cards on Rod Laver Arena?

Russian fifth seed Daniil Medvedev is being put under serious pressure by Thailand's world number 418 Kasidit Samrej.

Medvedev is a three-time Australian Open runner-up, including last year when he lost to Jannik Sinner despite leading the final by two sets.

Samrej, meanwhile, won the Asia-Pacific wildcard playoff to qualify for the Australian Open, having never previously competed at an ATP Tour event or a Grand Slam tournament.

It's safe to say the 23-year-old Samrej is producing the performance of his life, while opposite him Medvedev has cut a frustrated figure - breaking a racquet by repeatedly hitting it against the net.

But Medvedev recovered in the fourth set to force a decider and will be expected to now complete the job.

In the men's draw, American fourth seed Taylor Fritz opened with a straight-set win over compatriot Jenson Brooksby, winning 6-2 6-0 6-3.

It was a significantly less straightforward start for Danish 13th seed Holger Rune, who played out a five-set first round match against China's Zhang Zhizhen, which he eventually won 4-6 6-3 6-4 3-6 6-4.

Britain's Cameron Norrie is out after he suffered defeat by Italy's Matteo Berrettini. That was despite Norrie winning the first set, before falling to a 6-7 (4-7) 6-4 6-1 6-3 loss.

Britain's Emma Raducanu overcame second-serve wobbles to start her 2025 season with a scrappy win in the Australian Open first round.

The British number two, whose preparations were disrupted by a back injury, won 7-6 (7-4) 7-6 (7-2) against Russian 26th seed Ekaterina Alexandrova.

Sixth seed Elena Rybakina took just 53 minutes to complete dominant straight-set win over Australian teenager Emerson Jones.

The Kazakh, runner-up in Melbourne in 2023, conceded just two games on Margaret Court Arena in a one-sided 6-1 6-1 victory over the 16-year-old wildcard, who is ranked 293 in the world.

Eighth seed Emma Navarro and ninth seed Daria Kasatkina have also progressed in the women's draw.

Good morning!

And welcome back to the Australian Open, where day three of the year's first Grand Slam is well under way.

We'll bring you up to date with everything that's been happening on Tuesday so far, plus all the latest action, with British number one Katie Boulter waiting patiently to get on court.
