Jannik Sinner has been ranked number one in the world for over a year, as he continues to prove his class on the ATP Tour.
The Italian star won his first two Grand Slam titles in 2024, taking home the Australian Open in January and the US Open in September.
Carrying that momentum through to the new year, Sinner retained his Australian Open crown, beating Alexander Zverev in the final 6-3, 7-6, 6-3.

He was, however, unable to win a third consecutive Grand Slam earlier this month, as Sinner lost to Carlos Alcaraz in a five-set epic at Roland Garros.
As Sinner looks ahead to Wimbledon and a chance for redemption, his coach Darren Cahill has revealed how long the world number one plans to keep playing tennis for.
Darren Cahill says Jannik Sinner doesn’t see himself retiring from tennis until he is 37 or 38 years old
Appearing as a guest on the latest episode of Served with Andy Roddick, Cahill suggested the age at which Sinner will retire from tennis.
“He just loves the sport. He wants to get out there and play for the next 15 years,” said Cahill.
“He can see himself playing when he’s 37, 38 years of age. I don’t know about you, but I couldn’t do that when I was playing.
“I was trying to make it to the 30s and I didn’t even get it that long in my career, but these guys have a different perspective now about how long a tennis career could be because of the legends that have just played and extended their careers for so long and had so much success.

“So these young players coming through are investing in their careers at an early age to make sure they get the longevity.”
Cahill went on to explain what Sinner is really like behind the scenes.
“It is as good looking from the outside as it is from the inside. He’s a good young man,” he said.
“I don’t want to call him a kid, but in a lot of ways, he’s still a young kid. He does teenage things and he has a normal life away from the tennis court.
“But you know what he has? He has great self-awareness, and I think for any great champion in any sport, you have to be self-aware.”
The Australian believes Sinner will need to use every ounce of self-awareness he has to move on from his devastating French Open final defeat.
“You have to know how to handle yourself, how important something is to be able to deal with disappointment, to not carry on like a pork chop if you win a match, to not be an idiot if you lose a match, to have a way to deal with failure and success pretty much in the same way,” said Cahill.
“Yes, you get a little bit excited if something great happens, but don’t get too down. If something bad happens, try to learn from it and move on, and get better.
“He does all these things, and then he has an incredible work ethic. He has a wonderful resilience, and that resilience will be tested after that match in Paris to see how quickly he can move on.
“It doesn’t matter if he loses matches in the coming weeks. It’s more about how you handle yourself through those moments, and you just keep pushing and pressing, and he’s willing to do that.”
Sinner will have a chance to return to winning ways when he plays his first-round match at the Halle Open against Yannick Hanfmann on Tuesday, June 17.
At what age does Carlos Alcaraz plan to retire from tennis?
Speaking to magician Daniel Fernandez in 2024, Alcaraz picked the year he planned to retire from tennis.
“The year? Alright, it’s 2024 and I’m 21, 2037? Thirty-four, yes that’s the last one. The true greats play a long time, I want to reach that peak,” he said.
Alcaraz and Sinner have dominated Grand Slam tennis over the past 18 months, as fans will be glad to hear they plan on sticking around for the long haul.
