Jannik Sinner has enjoyed another stunning season on the ATP Tour, which continues this week at the Vienna Open.
Sinner is the top seed at the ATP 500 tournament this week, and takes on Daniel Altmaier in his opening match.
The duo have met on three occasions so far, with Sinner experiencing two wins and one loss against the German.
World number two Sinner is eyeing a fourth ATP title of 2025 at the Vienna Open, and the 22nd of his career.
Sinner credits much of his recent success to Darren Cahill, who has coached the Italian superstar since 2022.

Cahill is, however, set to leave the player at the end of the season, but Sinner remains hopeful that there will be a reverse of that decision.
He told ATP Media: “We haven’t talked yet, to be honest. We said we are going to finish the year, and then we might ask him for a long chat, trying to convince him.
“But in any case, if he stays or not, he has been an amazing person and obviously a coach for me to hold the whole team together in the tough moments.
“He is like a second father to me, so I’m happy to have him here. It’s a huge privilege to work with him. We aim for something very positive [for him to stay], and I will need a lot of hope for that.
“The results have been amazing, so I will try to make it happen for my own well-being. So I need that. He’s been important because I see the effort he puts in, working with a 24-year-old kid flying all over the world and putting in a lot of effort.
“He has family, he has many, many important things to do also off the court and managing this and always putting me basically in the first place, it has been amazing and I’m very sure we can make something very positive.”

Jannik Sinner analyses his season so far ahead of the Vienna Open
Sinner enters his latest tournament on the back of more success, having beaten Carlos Alcaraz in the final of the Six Kings Slam.
That arrived after Sinner retired during the Shanghai Masters with cramp, but he’s certainly feeling good ahead of Vienna.

| 2 | 43 | 6 | 3 | $12,346,528 |
Analysing his latest season, he said: “I’m seeing my year as very high, winning two grand Slams and making the final in the other two biggest tournaments we have, winning Beijing recently.
“The last week[s] were a great confidence boost and for me, most importantly, that the mental aspect is in the right way, in the right spot. I’m very happy and grateful for that. I feel good at the moment.”
His 2025 so far has included reaching all four Grand Slam finals, two of which he lost and two of which he won.
And while it wasn’t affiliated with the ATP Tour, triumphing at the Six Kings Slam in Riyadh will have boosted him further.
