Don't change the subject... Here I'll post Rafa the King's beautiful reply:
No he is the only one. In the open era only Wilander, Agassi, Nadal, Federer and Djokovic have won slams on all surfaces.
Nadal was the first to hold slams on all surfaces, since then Rog and Novak have done it. He is the only one to do it twice.
Nadal is the only one to have won on all surfaces in one calender year.
Wilander and Nadal are the only ones to have won 2+ slams on all surfaces
1) Connors was the first player in the open era to win slams on three surfaces,
which he did in Career AND at the same GS...then :
2) Wilander
3) Agassi
