He's always had the game and ability, just needed to apply himself. Now he's working hard off-court he can go far.
It was always obvious he had talent. I didn't realise just how talented though until these last few matches. He's proving that these aren't just one-off performances, but his actual level.
If he can sustain this level (if not improve further) over a whole year he will be a top 50 player (if not higher). As it is, he's only shown this kind of form since about June. That's a lot of points to pick up from September to May. I really hope he continues to play like this for the rest of the year and really proves it's not just a one-off run.
