Angelique, I was just checking the tournament site and I don't see his name anywhere. He didn't get a wildcard cos they just gave the last one to Mariano Puerta (the other two to Mexican players). And his name is not in the qualification list. Hope he's not ill or injured!
I believe that Costa will be withdrawing and possibly Nadal also to prepare for Davis Cup in Slovakia...
