Jannik Sinner has had a rough few months. Though he reached the quarterfinals at the Australian Open where he lost to Stefanos Tsitsipas, his results have been sub-par by his standards.

Sinner quit with his longtime coach Riccardo Piatti and hired Simone Vagnozzi as his new coach. Even though Sinner is only 20, he realized that things are not working and was willing to make changes that will pay off in the long run.

In an interview with La Gazzetta dello Sport, Sinner talked about the things he has been working on with new coach Simone Vagnozzi.

Simone Vagnozzi and I started working on the serve, on the backhand, on doing something more at the net. No upsetting, however, because the attention remains focused on not losing my fundamental characteristics, the ones that led me to arrive in this ranking. I am satisfied because we are working very hard on the pitch, as I like it. There was a good feeling right away and not just in terms of tennis. Vagnozzi is a passionate Milan fan and when we talk about football we get along well, we are on the same wavelength.

Sinner also talked about his long term ambitions

Talking about rankings is something that I never like to do. My ambition is to grow further. And if this path takes me one day to be number 1 in the world, it will be good. It will be a difficult undertaking, but this is my dream. You have to make sacrifices and sometimes you have to have the courage to make difficult choices like I did when changing coach.

Many expect Jannik Sinner to be a multiple-time grand slam champion. It’s amazing to see someone as young as Sinner take difficult decisions in such a thoughtful manner. These decisions will pay off in the long run for Sinner.

Alexander Zverev was handed a suspended eight-week ban for an outburst at Acapulco. During the incident, Zverev verbally abused chair umpire Alessandro Germani and hit the chair umpire’s chair four times.

Fans have been critical of the ATP for not giving Zverev a stronger punishment. Zverev represented Germany just a week after the incident.

But Zverev said that he has been meditating in an attempt to handle these types of situations in the future. Zverev said:

It still is embarrassing for me. Walking around the locker room, it’s not a nice feeling. But we all do mistakes. I’m also a human being, and I can guarantee you I will never act this way again in my life. It was definitely the worst moment of my life.

I’ve been doing work, meditation-wise. There are stress situations in everyone’s life where stuff like this happens. I’m not the first, I won’t be the last for something bad to happen on the court.

I know who I am as a person and this doesn’t reflect on me. I have played until 5 am the day before – the same day I went back to play doubles.

Alexander Zverev‘s suspended sentence means that any unsportsmanlike conduct or abuse until February 2023 will result in a ban. But Zverev is hopeful that he can be in his good behavior going forward.
