'I didn’t even warm up...' - Jannik Sinner opens up on hand tremors and physical struggles in 4th round vs Holger Rune

World number one Jannik Sinner was trembling as he suffered acute illness and distress during his fourth-round game against Holger Rune at the 2025 Australian Open on January 20, Monday. While the Italian sensation did manage to grab the stellar win 6-3, 3-6, 6-3, 6-2, his hand could be seen trembling, wrapped inside the towel. Sinner also told his team that he wasn't even able to move to his left in the game, allowing him to use his medical timeout in the third set of the game.

The Italian sensation overcame physical issues to knock out the Denmark star in round 16 and later opened up about the whole incident. Sinner stated that he already knew he would struggle like this as he woke up feeling unwell in the morning. With the two players tied into one set apiece, the world number one appeared to increasingly struggle with his movement in the game and overall abilities on the court.

"Today, this morning was a strange morning, because I didn’t even warm up today. I was trying to go on court as fit as I could be. I knew in my mind before the match that I would struggle today. Game-wise, I played well, I served very well. There were quality shots that gave me the confidence to fight on, and of course, the time off the court, the doctor and I talked a little bit. I don’t want to talk so much about how I felt today, I was not feeling really well. I think we saw that today, I was struggling physically," Jannik Sinner said.
