I think theres an element of bad management in there, certainly, which hasn't helped. Remember when he started, for around a year, he was playing only those heavy south american clay courts. I'm not convinced that was great for his development. Now, he's like, the same age as players in the top 50, but he really has had nothing in his career. Essentially he's starting again as a 20 year old.
I hope he can come through, because as a youngster wow, what talent. I'm not convinced though. His career reminds me so far of Vojislava Lukic's in the womens side, and we all know how that finished.
Actually, that was the best option. It's on clay and near to Bradenton. Clay is always the best opinion for young player. For his game and for his bones. How hurted he would be that he played hard courts.
After all of this injuries I don't think he will make anything big unfortunately.
It's just hard to go to the top: you need alot of talent, alot of money, good head and stay helth. If you have luck you are born in big tennis country (like e.g. France, Great Britain, Australia) you don't need money, they will just take you to the tennis academy.
