Del Potro - 7
Good tournament. Went as far as he could go given his current condition.
Berdych - 9
Was not allowed to be in the final, but played more than well enough to be there.
Cilic - 6
Very good tournament overall, but the mother of all chokes against Murray leaves a very bitter taste, very bitter.
Nishikori - 6
Played decently, lost to an on-fire Cilic in R3.
Djokovic - 8
Good tournament, just unlucky with the conditions in the final.
