I know Bollie well and he is as true a Legend and one of the best if not the best player on WGT and even nicer of a person. You have no idea how many friend requests, game requests, etc. he gets and why should he play you, he has nothing to prove against someone who has won no majors on WGT and has an average about 10 strokes higher than his.
If you want to call out someone, wait till you have proved yourself before you do it.
