The leader board for a given PGA event typically contains each golfer that participated in the outing. A PGA Tour Money board leaders list typically includes any players with accumulated earnings in PGA-sanctioned events during that year.
In addition to over/under par, many event leader boards include round-by-round results, and they change in position from the previous day of play. MC and WD designations are used to identify players who did not complete each round of the event due to a missed cut or withdrawal.
The money leader board ranks players by total earnings and includes the number of events in which they played. From Chris DiMarco's $6,370.00 to Rory McIlroy's $8,280,095.50, the 2014 PGA Tour season saw 377 different players win money.
