No he wasn't!?
What I mean by "required" is--players who's ranking are high enough to make the main draw at a Slam or a Masters Event are supposed to play there. Since they "have to" be there, they get the 5 points for a first round loss. But WCs are treated like it's any other tournament.
Any tournament that's not a Slam or a Masters event is completely optional.
Ok, thank you for you answer, now I get it!!!
Another question then...
If you go through the qualies of any tournament but you lose first round, do you only get the points for the qualies or also some points for the first round? I guess only points for going through the qualies, right?
