Nadal fans claim tiredness for the 08 beating there but Murray played 4hrs with Isner a day before that match while Roddick bared his backside for Rafa 6-2 6-2 6-1 on Ashe.
They can't have it both ways.
Uhm, Nadal was tired not because of the previous match, it was an accumulated fatigue of sweeping most of clay titles, RG, Queens, Wimby, OG, Toronto, semis at Cinci. What was Murray doing during that time? Eating cooking and drinking warm milk at home. He was fresh and didn't play too many matches, especially on clay for obvious reasons.
