Idiotic and lucky he didn't cause a serious injury.
Thought we might have seen the last of this stupidity after Nalbandian at Queens.
Obviously not....
it was really unlucky for the young lad. Of course, he shouldn't have done it, but it was a bit of a freak bounce and he had no idea the ball would have hit the umpire.
I think he would have lost anyway, but a sad end to the match.
