not a particularly good match. the most memorable thing is djoko clobbering nadal until he begged for the match to be suspended.
if you ever played tennis on a clay court you'd be aware of how big a difference moisture makes to conditions, ball bounce, movement, etc. Djokovic lucked out that it was raining for the entire third set, it was dumb of the officials to not suspend play earlier. remind me again, why Nadal was beating Djokovic so badly the first two sets when conditions were absoultely normal and how the weather is meant to be when playing on clay?
it's a poor excuse to say your man had momentum when he happened to suddenly play very well in wet conditions that make the ball bounce low and the courts play uncharastically as far as clay is concerned
