HOW THE RANKING SYSTEM WORKS
Eligible tournaments from the leading professional Eligible Golf Tours around the world are included in the Official World Golf Ranking (OWGR), as well as the Major Championships, World Golf Championships, Olympic Golf Competition, and the World Cup of Golf. Team events are not eligible for inclusion.
Any players competing in these tournaments will receive ranking points subject to their respective finishing position.
The OWGR System is run over a two-year "rolling" (104-week) period.
Ranking Points are derived from each tournament's Total Field Rating.
Ranking Points are maintained at full value for a 13-week period to place additional emphasis on recent performances.
Ranking points are then reduced in equal decrements for the remaining 91 weeks of the two-year Ranking period.
Each player is then ranked according to their average points per tournament, which is determined by dividing a player’s total number of points by the number of tournaments they have played over that two-year period.
There is a minimum divisor of 40, and a maximum divisor of a player's last 52 tournaments applied to the tournaments that the player concerned has played over the two-year ranking period.
TOTAL FIELD RATING
Every player in a tournament field contributes performance points as determined by the player's individual Strokes Gained World Rating. The sum of these Performance Points determines the Total Field Rating.
The Ranking Points Breakdown is derived from each tournament's Total Field Rating.
Ranking points are awarded to all players who make the cut and complete an event, subject to their finishing position in the tournament.
Points awarded will be fractionally greater than the Total Field Rating when more than the projected number of players make the cut and complete the tournament.
Points awarded will be fractionally less than the Total Field Rating when players who have made the cut are disqualified, retire, or withdraw from the later rounds causing the number of players completing the tournament to be less than the projected number of players to make the cut.
The four Majors: the Masters Tournament, PGA Championship, U.S. Open Championship, and The Open Championship, are rated separately and awarded 100 First-Place Points.
THE PLAYERS CHAMPIONSHIP
THE PLAYERS Championship is rated separately and awarded 80 First-Place Points.
STROKES GAINED WORLD RATING
A player’s Strokes Gained World Rating is based on a player’s actual scores in stroke-play events and adjusted for the relative difficulty of each round played over a rolling two-year period.
To place more emphasis on recent performances, a similar weighting system as that applied to World Ranking Points is utilised (i.e., a 13-week period of full weight, thereafter, reduced in equal decrements).
Scores from completed 18-hole round stroke-play events are eligible for inclusion in the Strokes Gained World Rating.
Each Strokes Gained World Rating has a corresponding value of Performance Points determined by the Performance Curve.
Players with 10 or fewer recorded scores are assigned a value of 0.01 Performance Points.
Players with fewer than 50 recorded scores can each contribute a maximum of 10% of the tournament Field Rating.
Each player's scores from stroke-play events over two years are used in a series of simulated events to determine the average Ranking Points expected per each Strokes Gained World Rating, which is then plotted to create the Performance Curve.
For tournaments curtailed to 36 holes because of inclement weather or other reasons, the points breakdown will be reduced by 75%.
A tournament will not be reduced below its historic minimum points level.
Shall mean a tournament that includes both men and women, playing the same course(s) but from different tees, for one prize fund on one leader board.
Only the men's individual results will be eligible for inclusion.
LIMITED FIELD TOURNAMENTS*
Limited field tournaments are defined as events with fewer than 30 players.
Special Tournaments are defined as a tournament that is sanctioned by an Eligible Golf Tour but does not count towards the Eligible Golf Tour's end-of-season ranking list.
*Limited Field and Special Tournaments must be individually reviewed by the Technical Committee and approved for inclusion by the Governing Board.
