Now let me start out by saying this is not a thread accusing a player of steroid use whatsoever. However, I personally do not think that he is natural... Or rather not as natural as everyone else is that plays on the ATP tour. Anyways, could somebody please explain to me how in hell did this guy reach this level out of nowhere? I say nowhere because his rise started after USO 2010 where he lucked out on Federer... but he was still a nutcase in the finals vs. Nadal. Now, we all know it began during Davis Cup... but really, the guy had the weakest of stamina in 2010... How did a player of his caliber (at the time) get so much better in 2011? Don't give me that gluten mess... Some people say he sold his soul to the devil... Some say it's due to the the colored juices he drinks during matches... Some say he was always this good and needed to mature... Some say he went back to his old racket... I mean this was a guy that was known for quitting when the going gets tough less than 24 months ago... and now suddenly he is regarded as a mental giant comparable to the likes of Rafael Nadal?
