Because Nadal was a clay player only before 2008.
Yet he beat Agassi in Montreal to win a master 1000 title, the same Agassi who reached the final of the US open.
Nadal lost early at the US open because he was still a clay player, who can't play great on other surfaces.
He also took Federer to 5 sets in Miami and won Madrid Indoors in 2005, he took Lleyton to 5 at the AO as well. He was a good hard court player in 2005 and onwards, he just often ended up facing on fire opponents. Blake was playing fantastic hard court tennis at that time, that's why he lost early at the USO. The field had a bit of depth to it, Nadal's draws at the USO in 2010 and 2013 was cake walks. Blake hit 53 winners past Nadal in that match at the USO, he was playing way better than anyone Nadal faced in his runs bar Djokovic.
Agassi was in better form at the USO compared to Montreal.
