So I don't know why he was so distrough about it.
Just accept it and move on to try to win the rest of the matches.
I do think he is just giving up on himself way to early.
He does have the strong forehand in all of tennis even with the multiple wrist surgeries he had to endure.
Just sad to see him that way after the first set was said and done with going in murray's favor.
He still has a problem with that wrist, you can see how is playing backhand, lots of slice backhands. It is not his style. I think that he could not do more, his game is suffering because of that and he was aware that can not do his best. I am not favoring nobody but I am kinda sad for Delpo, he is a great fella and great tenis player.
If he had a healthy wrist then he would be closer to a level of Djokovic standard and might actually beat him the way Novak showed he had difficulty in his encounter with the other Argentinan that made it to the final 16 in his last match.
