I think Djokovic has cast a spell over his opponents 
, everyone who faces him gets injured.Even in today's match Jo Tsonga, retired after two sets. his second round opponent, Jiri Vesely also didnt play because of an injury as well as his third round opponent Mikhail Youzhny. Is this going to be Djokovic's lucky tournament

Is this going to be Djokovic's lucky tournament Yes, it's true! Djokovic has won only 8 set instead that 15 and is already in the semifinals (1 W.O. and 2 opponents have abandoned).
Perhaps his opponents were not injured but knowing losing decided to save energy for the next tournaments ...
Very possible, now that they cant defeat djokovic, why they played, just retire for next tournaments, maybe will win a tournament because of this time early retired.
