Considering Chang's situation, where the whole crowd was basically rooting for him after seeing him hit some incredible shots while cramping, his was a pretty smart play to mess Lendl up
In Hingis' situation, the whole crowd was already against her for going onto Graf's side, and yes she still wanted to win the match, but didn't she do it twice? It certainly didn't help her as the crowd got on her case more
Great play! Are you kidding me? Of course great play! Against Lendl, go watch it again. The funniest part is how pissed Lendl gets, big baby. Chang was all cramped up... LOL! Respect Chang. After all, he's still the youngest player ever to have won Roland Garros.
