Doha - Roddick (absolutely dismantled him)
Rotterdam - Nadal (think Nadal was injured so the final set was a formality)
Miami - Djokovic I think?
Queens - think it was James Blake!
Montreal - this one is puzzling me, either Del Potro or Fed. Del Potro was pretty strong around summer 2009 so I'll go for him.
Valencia - no idea
Yep, five correct but I'm also drawing a total blank on Valencia. Will have to look it up...
