Alexander Zverev seems to be breaking a lot of rackets lately and blaming it on the racket (remember the comments about the rackets at the Federer match at Hopman cup 2019). There might be something there, but probably not what you might think.

Now, what is the difference between Zverev and Tsitsipas?

To get straight to the point it’s their racket set ups. Zverev uses a more polarized racket with a lover MGR/I and Tsitsipas the exact opposite. These are the specs Zverev used some time ago and I think it’s safe to say he is still using about the same specs as nothing significantly changed in his game.
