Becker praises Sinner's serve improvements: "It was the shot he was missing this summer"
Jannik Sinner was able to rely on his serve during the indoor tournaments, where he managed to win the Vienna, Paris, and ATP Finals tournaments consecutively.
Serve improvements since the US Open…
In comments reported by Tennis World USA, Boris Becker wanted to praise the Italian's performance in this area of the game: "I think Simone Vagnozzi and Darren Cahill did a fantastic job after the US Open to improve Jannik's serve.
It was the shot he was missing this summer, especially in the US Open final, where Carlos dominated him on serve.
…thanks to a change in technique
The serve is the only shot where your opponent has no control; it is entirely in your hands. Since September, Jannik has slightly modified his technique and toss.
The main difference between last summer's Jannik and today's Jannik lies in his serve. Indoors, that counts for a lot."
