I think he goes undefeated. At least until a possible match against Ferrer, even then I put him fav, since he will have many matches under his belt by then. I think he will probably tank IW and Miami, and then get back to MC. This could be an epic clay sweep from Rafa...I wouldn't be the least bit surprised.
