We have all info's about Borna now:
Interesting, all 3 best players of all time (Federer, Sampras and Nadal) are 185 cm. Borna has 79 (he got alot kilos in recent time) and he will build up even more, Federer and Nadal has 85 kilos and when you see them what they have looked like with 17 that's like Borna looks like today. Sampras had 77.
So this is the best high for tennis. You are tall enough to have great serve plus you are short enough to be a great mover. Borna has great serve plus he is great mover. He should fix his forehand. He doesn't hit propertly, he is going for too much spin but doesn't do that well, he should hi it more flat.
