Nadal completed his career GS profiting from the absence of the defending champion who demolished him in that same tournament the year before.
So it would be the same for the 3 of them.
Are you comparing Delpo/USO with Nadal/RG???? No Delpo and no nobody else would stop that Rafa, in USO 10. And Rafa always prooved he is unbeatable in RG for 7(SEVEN) fucking years!!!! Delpo is just a slam flucker!!!
