I will just a quick comment here: HUGE match for Jannik Sinner against Taylor Fritz today. If Sinner wants to be world number 1 someday (one of his goals), then this is the type of the match that he should able to win, no excuses! Yes, I understand that Fritz is playing well and he is playing under home soil, but Fritz is no Nadal/Djokovic, Alcaraz or Medvedev. If Sinner plays at his best, he should able to beat Fritz.
The reason I am saying this is because I think that Sinner can be like Medvedev: Potentially winning multiple slams, become no. 1 player, win a lot of ATP Titles, he is REALLY good at tennis plus he is a mentally tough player. The only reason he might not able to reach those goals is because of his injuries and/or he will not be athletic enough to become a great player.
So he needs to start reaching SF/F or even win some of these M1000, 500 tournaments or he will be like another Rublev, imo.
