Australian Open 2025 LIVE: Latest results and set-by-set updates as Jannik Sinner’s telling move sparks major concerns ahead of his quarter-final clash vs Alex de Minaur

Good afternoon and we’re back again here at Melbourne Park!

It’s been a warm and windy day here at but the conditions are perfect for tennis and we’ve got a few big matches kicking off tonight.

Ben Shelton has just taken the first set against Lorenzo Sonego in their quarter-finals clash, which will be followed by the match of the evening with Jannik Sinner set to go head-to-head with Alex de Minuar at the Rod Laver Arena later tonight.

But huge concerns are mounting over the Italian’s fitness. It came after reports claimed yesterday that he had allegedly been ‘suffering from pneumonia’.

It came after he was caught shaking uncontrollably during his victory against Holger Rune on Monday.

The reigning Australian Open champion had left the court to receive medical treatment and had told his team that he was feeling dizzy.

Despite that, Sinner has been back in practice this morning ahead of his match against De Minaur but the world No 1 is understood to have practised today in a behind-closed-doors session at Melbourne Park.

It is unknown the true reasoning behind the move and perhaps it may be a precaution to ensure no prying eyes can see him warming up ahead of tonight’s crunch match.

But the move has still attracted speculation and concern that he is still struggling with an illness.

Iga Swiatek advanced to the semi-finals of the Australian Open on Wednesday afternoon after securing a 6-1 6-2 victory against Emma Navarro.

But there was a controversial moment in the match. The five-time Grand Slam winner was brought to the net by Navarro and she appeared to fend off a drop shot from the American star.

Navarro played on and clipped the ball to the other side of the court with Swiatek scrambling across to hammer back at her opponent to win the point.

But Navarro was incensed by the moment, confronting the umpire in a fit of rage asking why she was not allowed a video review.

Navarro, had been pushing for a break of service at the time, but could not make the breakthrough with Swiatek holding.

Sinner opened up on how he was feeling during his post-match press conference earlier in the week.

But he did not speak out on the specific ailment he had.

I was not feeling really well,’ said the 23-year-old. ‘I think we saw that today I was struggling physically. I knew that it was going to be very, very difficult today, playing against a tough opponent but also playing against myself a little bit.

I at least felt slightly better when I went back on court. I felt like the face looked a little bit better, the colour was a little bit back. The doctor gave me some medication.

Sinner had also consulted a medical professional before heading out onto court for his clash against Rune on Monday, adding to speculation that he had been suffering from an illness prior to the fourth-round clash.

I talked with the doctor before already, before going on the court. I had a little checkup.

Yeah, it was a bit helpful. I at least felt slightly better when I went back on court. I felt like the face looked a little bit better, the color was a little bit back.

So, yeah, that helped, for sure. You know, it’s a toughconditions. You know, yesterday was hot. Today was hot again.

You know, every player, you know, struggles a little bit. When you’re not there health-wise where you want to be, it’s also even more difficult, but it helped, yeah. It gave he some small medication, and then it wasn’t slightly better.

Major concerns arose over Jannik Sinner’s wellness during his victory against Holger Rune earlier on Monday.

It was a particularly warm and muggy day in Australia, with temperatures topping out at 32ºc.

Bashed his way to a 6-3 lead in the opening set but began to look increasingly uncomfortable during the match. At one stage he was even seen shaking.

Jim Courier claimed that he looked like a ‘zombie’ as the Italian sat down on his bench during the interchange.

He would later leave the court for a medical time out that lasted around 11 minutes – with Rune claiming that he had been left to ‘cook in the heat’ on the court.

He stated that he had been feeling unwell before the match but returned, losing the second set before sealing a 6-3, 3-6, 6-3, 6-2 victory.

Tonight’s match should start a little earlier than yesterday’s huge clash between Novak Djokovic and Carlos Alcaraz.

Play is expected to get underway between 7pm and 7:30pm after Ben Shelton and Lorenzo Sonego’s quarter-final clash at the Rod Laver Arena.

And I’ve just seen De Minaur arriving at Melbourne Park for the match.

He’s making his way through the player’s gym area as he prepares for the blockbuster clash.

It’s the first time in his career that De Minaur will have reached the quarter-finals of his home slam and there was a huge outpouring of emotion after the Australian booked his place in the tournament on Monday night.

His fiancee, Katie Boulter and mum Esther were both seen jumping up and celebrating as De Minaur pushed his way past Alex Michelsen in three sets.

Esther even began to well up before giving Boulter a huge hug after the match.

Katie Boulter issued a cryptic message on Tuesday night indicating that she may have left the country.

She and Alex de Minaur have dazzled over the past two weeks in Melbourne but the Brit suffered a disappointing second-round defeat against Veronika Kudermetova last Thursday.

She’s since stayed in Melbourne to watch her new fiance battle his way to his first-ever Australian Open quarter-finals.

Boulter has been taken on board as an honourary Aussie by many of the home fans at Melbourne Park, with one commentator even asking: ‘Can we start calling you Aussie Kate?’

In the Instagram post, she published several pictures of her playing in Melbourne, Sydney and a snap of her and De Minaur at Kooyong.

She captioned the post: ‘Thank you Aussie for making me feel like I’m at home.’

But the British star added two emojis following the note that indicated she may have left the country.
