Australian Open 2025 LIVE: Latest results and set-by-set updates as Jannik Sinner's telltale move raises major concerns ahead of his quarter-final clash against Alex de Minaur

Katie Boulter issued a cryptic message Tuesday night indicating 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.

Since then, she stayed in Melbourne to watch her new fiancé reach the Australian Open quarter-finals for the first time.

Boulter has been considered an honorary Australian 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 posted several photos of her playing in Melbourne, Sydney and a photo of her and De Miñaur in Kooyong.

She captioned the post: “Thank you Aussie for making me feel at home.”

But the British star added two emojis after the note indicating that he may have left the country.

Good afternoon and we're back here at Melbourne Park!

It's been a warm and windy day here, but the conditions are perfect for tennis and we have some big matches starting tonight.

Ben Shelton just won the first set against Lorenzo Sonego in their quarterfinal clash, which will be followed by the evening match as Jannik Sinner takes on Alex de Minuar on Rod Laver Arena later tonight. .

But concerns are increasing over the Italian's physical condition. It came after reports yesterday claimed he had allegedly been “suffering from pneumonia”.

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

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

Despite that, Sinner returned to training this morning ahead of his match against De Minaur, but the world number one is understood to have practiced today in a closed-door session at Melbourne Park.

The real reason behind this move is unknown and is perhaps a precaution to ensure that no prying eyes can see him warming up ahead of tonight's crucial match.

But the move has still sparked speculation and concern that he is still battling an illness.
