All (or at least almost all) tournaments at ATP level have a qualifying competition, from which players can get into the main draw.
Do players get some points if they win a match in the qualifying rounds? If not, do at least winners of the qualifying get points? (IIRC the players who enter main draw get points even if they are defeated in the first round already.)
Both Wikipedia article and 2014 ATP Rulebook mention additional qualifying points. (For example, 25 points in Grand Slams.)
The exact quote from rulebook is this:
Players qualifying for the main draw through the qualifying competition shall receive qualifying points in addition to any points earned, as per the following table, with the exception of Futures.
I am not sure whether I understand this correctly. Is this the number of points that a player who qualified to the main draw receives? (In addition to the points he receives from the competition.) So the players who do not qualify do not receive any points?
