I saw him in his big week, when he won a 15k+h title. He has hard baseline shots, but something is missing to make him a big talent imo. He doesn't have the biggest touch and isn't solid enough from the baseline, too many unforced errors. I expect him to reach challenger level.
I don´t think so. Of course, he has to be more constant, he still makes too many unforced errors, but this is something, you can learn. I think, e.g. Andreas Beck didn´t play better at the same age, both play similar. Let´s wait for the next two or three years. I expect him to reach at least Top 100.
