Kohlschreiber Djokovic at Roland Garros

Stosur spanking Serena last years US Open. on the anniversary of 9/11 FFS! didnt see that one coming. big momma looked unbeatable for weeks before

Berdych losing to Robert at RG 2011 yes I will always remember that match, he was 2 sets up and then decided he just couldnt care less about tennis anymore! Ever since that time I will never trust Berdych.  The most embarrassing performance I can remember from a top 10 player at a Grand slam.

@bb66 Cheers mate.

Always funny when Murray loses to a far lower ranked player.
Clearly just can't be bothered sometimes.
