Sure, he has had a great season, but imo he can improve massively, and he cant really accept a H2H like this vs Raz. I agree, AO26 is all that matters, he should use the rest of the year to aim for that, even if it could cost him YEC and a few masters.
Agreed. Having another hugely successful season, winning the tournament that he craved more than any other, while still also having clear room to significantly improve his game (notably his serve and adding more variety to his patterns of play) is a good and encouraging sign from his perspective.
Brad Gilbert recently said on the Roddick podcast that he didn't think Sinner was the finished product yet - I definitely agreed with that.
