Golf tournament fields are bigger than the total number of spots paid out. A cut is used to decide which players will advance to the weekend and, as a result, qualify to earn a payment from the tournament based on their finish position. The player who ranks lowest among those remaining plays over the next day or two to determine whether they remain in the tournament at all. The most common type of cut is called the "cutoff". At a golf tournament that uses this system, everyone who finishes inside the top nth percentile (where n is usually between 100 and 150) qualifies for the payouts. Those who don't make the cutoff are eliminated from further consideration. The reason there is a cutoff is so that only the best golfers remain in the tournament. If everyone who entered the tournament were guaranteed a place in the final group, no one would have an incentive to do well after entering. Also, with more people participating in golf tournaments, the better players are likely to find other opportunities to win money. Having a cutoff ensures that these higher-ranking players stay in enough events to continue finding good opportunities to win money. There are several other types of cuts used by different golf tournaments. For example, some tournaments allow you to improve your score each day in order to keep playing. These are called "replay" cuts because you can replay the previous day's round under new rules.
