He's won MC, Barcelona and Rome in straights. Madrid and it's blue clay was the one aberration. Winning titles without dropping a set isn't easy so wel done Rafa - clay God in business so far this season.
Last player to take a set off him on red clay - Del Potro.
“There are always moments when one feels empty and estranged. Such moments are most desirable, for it means the soul has cast its moorings and is sailing for distant places. This is detachment -- when the old is over and the new has not yet come. If you are afraid, the state may be distressing, but there is really nothing to be afraid of. Remember the instruction: Whatever you come across -- go beyond.”
Only Federer in the Roland Garros final (7-5) and Del Potro in the Davis Cup Final (6-1) managed to take sets off him in this period. Quite impressive, he hasn't even played that many tiebreaks either.
