How often to juniors actually come back to defend their title (referring to Berta)? I mean, there's not much to be gained from it, especially because he's already been number one.
My thoughts, also. What more could be achieved for him here that he hasn't achieved already?
I also found strange that the ones having already some good pro results decided to play junior tournament, even if it was a GS.
If would be OK if it was the first appearance imo, but otherwise I think it would be better for them to focus on the future pro career.
