don't forget the tiebreaker which is the total # of birdies in the entire tournament..there are 88 players in the 1st 2 rounds and 50 plus ties in the final 2 rounds---might need a calculator :-)
also, if any of your 4 picks WD, DQ, or misses the cut, you can replace them from a player in the same category before the start of the next round...
