How many lucky loser spots are up for grabs? Is it done on seeding or is it a lottery? If it is seeding who is first, second, third and fourth in line? Who are injured and pulling out?
The four highest ranked players to lose in the last round of qualification in Grand Slam tournaments are drawn to determine the order in which player is allowed to enter the draw, first, second, third and fourth. (From wikipedia.)
These highest ranked losers are now known:
Robin Haase (NED) (2)
Fabio Fognini (ITA) (7)
Bobby Reynolds USA (9)
Wesley Moodie RSA (14)
So, first these four will be given a nr. 1, 2, 3 and 4 by lottery.
Now, as far as I know there is, at this moment, only one player that withdrew from the main draw:
Gael Monfils (FRA), hamstring injury
The LL with nr. 1 will thus be drawn together with the other qualifyers when the placing draw is made. Monfils place is added to this. If another player withdraws, nr. 2 also gets in, etc.
And if after the placing of the quallifyers and lucky losers, but before the tournament started another player withdraws, the next lucky loser gets this place, etc.
