He’s 19 and has already won 4 titles this year. Beaten Djokodal back to back.
There are holes in his game and some of the hype was premature, admittedly. He’s incredibly error prone for a top guy and does not have a reliable serve or return yet. Even still, look how damn good he is even with those limitations.
As for his future: the elbow injury is massively concerning but he’s easily the most promising youngster in a decade. It would take a total disaster (like, career ending injury or some sort of alcoholism/drug addiction) for him not to eventually win Slams.
