Despite his recent success, Jannik Sinner still feels like he needs another 2-3 years to better develop his body to be in peak tennis form. The 21-year-old Italian who is in his second Masters semifinal today against Carlos Alcaraz, sounds to be in no hurry to reach the top. But he’s making slow and steady improvements.

“We have a lot of work to do still,” Sinner said. “I give my body a lot of time to develop. But for sure now I am in a much, much better position where I was one year ago. We take care of quite everything. I know also my body better, when to practice or when maybe to do only gym.

“All the injuries last year and a little bit also the bad luck we had as a team gave us still the possibility to think about or to improve for this year and hopefully also for the upcoming years.

“Also mentally was tough last year, so this year I feel much, much better for year. So yeah, I am for sure in a good position right now, but I feel like we have so much work to do still. I think in two, three years I will be in a very, very good position physically.”

Sinner has been a force since Australia, reaching back-to-back finals with the Montpellier title and then the Rotterdam final losing to Medvedev.

He comes into the semifinals having won 11 of his last 12 matches but will face World No. 2 Carlos Alcaraz today. Sinner is just 3-16 against the Top 5 however he’s starting to turn things around against the very best. He just scored two of those wins beating defending champion Taylor Fritz on Thursday and Stefanos Tsitsipas last month in Rotterdam.
