They had tee times up quite a bit quicker than the combined am/pro worlds I played in Ann Arbor. With that said, it seems to me, that tee times could be up as early as a week prior, with just one pool for the last entrants and those filling vacated spots, not learning until late. Correct me, if I'm wrong, but this seems to make sense to me? My guess would be that you fill the tee time slot of the person who vacated; but, still, that means, it would just be those who are filling vacated spots that wouldn't know until the very last minute and would understand that this is just part of the process. The only downfall I would see is if two spots on a card were vacated and due to the lateness of filling, no one wanted to step into said spots, and card would not have enough players to be a valid card. Seems that would be pretty rare though.
