Well, he has said in an intervew that he only does it if he feels it will help him get the frustrations out and get it all together. I´m all for it if it helps him win the match, like it obviously did yesterday.
It was harder to watch him about half a year ago when you could see he was not feeling it and just calmly lost one match after another, for me anyway..
I agree! Part of me enjoys when he breaks a racket on occasion. He doesn't do it often anymore and I also made him laugh one time when making a joke about it!
