For most professionals making a living from tournament golf can be challenging, as tournaments have entry fees and the associated costs of travel and lodging, plus the hire of a caddie. Moreover, most tournaments have a "cut" after the second of four rounds in which a minimum aggregate score is selected to eliminate roughly half the field and advance the remaining golfers into the final rounds. Of those players remaining, only some will take home significant winnings and those that missed the cut do not earn any prize money.
