Haas is a US citizen so he's basically playing a home event.
So your definition of vulture isn't about a player entering a weaker-than-his-ranking field then? it's a player entering a weaker-than-his-ranking "non-home-event" field. Got it.
And how do you know Wawrinka asked for a wild card and wasn't simply offered one?
I don't know, so I didn't say he asked for one. Reason I didn't say is because I did not think whether he asked for one or was forced to accept one (probably with money pointed to his head) is of any importance. The fact of the matter is that he is now in a event that has a significantly weak field, which I did not have problem with, and apparently so didn't you because your definition of vulture is a player entering a weaker-than-his-ranking field who has a surname of Monaco or Ferrer. Otherwise, I don't see you go around here criticizing Wawrinka, what gives? Is it only players who entered Houston who's not Americans (or Spanish since I don't see you criticizing Almagro either) are worthy of being called the word you hinted that started with a v? Casablanca is obviously no Houston.
Monaco, on the other hand, is playing DC in Argentina this weekend and Monte Carlo the week after, playing Houston in between has only one explanation. I'll give you a clue: it starts with a v and it has wings.
Lucky that Almagro, Haas, Wawrinka's respective country teams are all out of DC, otherwise, they will be in the same boat as Monaco. We don't want that, oh no, we don't.
