Well, Andy's team was very surprised too when they were told that Andy had put through a request to open his first match on Tuesday instead of Monday. It could very well be that the Organizers keep this as a secret and probably only happens between the players and the organizers. No one, perhaps not even the team , is supposed to know (in fear of leaking I suppose).
They have no reason to put Andy on Tuesday and as late as possible. You may think there's a big conspiracy going on there against Andy, but
If you think about it logically and reasonably, you will come to the conclusion that, they actually have no reason to do so. More importantly, Andy himself isn't saying anything about it. And neither is Rafa, is he? Typically at least Nadal would have said something by now.
