@bcwylie77: The biggest change in Jannik Sinner’s game wasn’t his forehand or backhand. It was his serve. With the guidance of Simone Vagnozzi, Sinner transformed it from a solid shot into one of the most dangerous weapons in tennis. More disguise, more variety and more free points. On grass, those improvements become even more valuable. The ball stays low, skids through the court and gives opponents almost no time to react. When Sinner is serving well, holding serve can look effortless. It’s one of the biggest reasons he has become such a force on grass and a Wimbledon champion. The scary part? He still believes there’s room to improve. Sometimes the biggest breakthroughs come from mastering the smallest details.
