Due to the multiplicity of names, there is often confusion as to what the PGA Tour organization does and does not run. Of the events in the PGA Tour schedule, it does not run any of the four major championships (the Masters Tournament, the U.S. Open, The Open Championship and the PGA Championship), or the Ryder Cup. The PGA of America, not the PGA Tour, runs the PGA Championship, the Senior PGA Championship, and co-organizes the Ryder Cup with Ryder Cup Europe, a company controlled by the PGA European Tour. Additionally, the PGA Tour is not involved with the women's golf tours in the U.S., which are mostly controlled by the LPGA. The PGA Tour is also not the governing body for the game of golf in the United States; this, instead, is the role of the United States Golf Association (USGA), which organizes the U.S. Open. What the PGA Tour does organize are the remaining 43 (in 2009) week-to-week events, including The Players Championship and the FedEx Cup events, as well as the biennial Presidents Cup. It also runs the main tournaments on five other tours: PGA Tour Champions, the Korn Ferry Tour (formerly known as Web.com Tour[31]), PGA Tour Canada, PGA Tour China, and PGA Tour Latinoamérica.[32]
Alternate: Events which are played in the same week as a higher status tournament (either a WGC or the Open Championship) and therefore have weakened fields and reduced prize money. They are often considered an opportunity for players who would not qualify for certain events due to their world rankings, positions on the FedEx Cup points list, or position on the Tour's priority list to move up more easily or have an easier attempt at a two-year exemption for winning a tournament. Because of their weaker fields, these events usually receive the minimum amount of world ranking points reserved for PGA Tour events (24 points) and fewer FedEx Cup points than most tournaments (300 points instead of 500). Alternate event winners also do not earn Masters invitations. Fields for alternate events have 132 players. These events have 12 unrestricted sponsor exemptions, four more than the regular events.
The number of Race to Dubai points available in the last three events of the season was increased, and the field size reduced. The aim was to make more players still have a chance of winning the Race to Dubai entering the final events. In addition, although the prize money was not increased, the bonus pool of US$5m would now be split among the top five players rather than the top ten. The money saved from restricting field sizes was used solely to increase the first prizes, which means that the tournaments would not have the standard prize fund distribution, and the DP World Tour Championship, Dubai would have the largest tournament first prize in golf of US$3m.[7]
