So, I understand what qualifying is. In a draw of 128 players at a major...let's use Roland Garros as an example, a certain number of players make it automatically--those ranked in the top 100, correct? I know the cut-off for a ranking for automatic entry is usually a few weeks before the tournament in question. Then 16(?) qualifiers (out of 128) will make it to the first round of the main draw. Typically, they need to win three matches, usually in three or four days, in qualifying, to get into the main draw. If they lose in the final round of qualifying there's a chance they might be a "lucky loser" and replace an injured main draw player. But my main question involves..who determines who plays Qualies? For a major, I'd imagine that every non top-100 player in the world would kill to play Qualies. Who determines who gets into the qualies? I'd imagine someone ranked in the top 200 probably has a pretty good shot, but what about beyond that? Then of course, there are also players who receive wild cards into qualifying. Tournaments at every level have qualifying...how do we figure out who gets to play Qualies at a major?
