Women's Golf World Rankings: "How Are They Calculated?"

Introduced in February 2006, Targeting 12 Tour Organizations
First No.1 Sorensutam, Weekly Rankings Announced Every Monday
Points Differentiated by Tour Scale and Participating Players

The women's golf world ranking is drawing attention because of Ko Jin-young, who is ranked number one in the world. On the 25th (local time), after the second major tournament of the year on the LPGA Tour, the KPMG Women's PGA Championship, held at Baltusrol Golf Club in Springfield, New Jersey, USA, she maintained her number one position. She has held the top spot for 5 consecutive weeks. Ko Jin-young surpassed Lorena Ochoa (Mexico), who was tied for first place, and set a record as the first woman in golf world ranking history to be 'Number 1' for 159 weeks.

Ko Jin-young is the 'Number 1' who has held the world No. 1 ranking for 159 weeks, the longest record in women's golf history.

The women's golf world ranking was first introduced in February 2006. Due to its sponsor, it is also called the Rolex Ranking. R2IT, a sports-related software development company located in Wellington, Florida, USA, manages the Rolex Ranking software. It is overseen by The Royal and Ancient Golf Club of St Andrews (R&A) and the United States Golf Association (USGA). The ranking covers tournaments operated by 12 organizations including the Ladies Professional Golf Association (LPGA), Ladies European Tour (LET), Japan Ladies Professional Golfers' Association (JLPGA), Korean Ladies Professional Golf Association (KLPGA), Australian Ladies Professional Golf (ALPG), and China Ladies Professional Golf Association (CLPGA).

The first world number one was the 'Golf Queen' Annika S?renstam (Sweden). All professional and amateur players who have participated in tournaments recognized by the Rolex Ranking are eligible. The ranking calculation method is similar to that of the men's golf world ranking. The Rolex Ranking Committee awards points differentially every Monday after all tours worldwide have concluded. The points are published on the official website. The average is calculated by dividing the total points earned over the past two years by the number of tournaments played.

The most recent 13 tournaments are weighted more heavily. Points vary depending on the tour, tournament scale, and the 'grade' of participating players. Points are awarded differentially for each tournament. The five major tournaments?Chevron Championship, KPMG Women's PGA Championship, U.S. Women's Open, Amundi Evian Championship, and AIG Women's Open?award 100 points. Tours such as the LPGA, LET, JLPGA, and KLPGA award 50 points.

Not all tournaments award points just for passing the qualifying rounds. However, major tournaments grant ranking points if a player advances to the main event. The world ranking serves as a criterion for eligibility in some tournaments. The LPGA grants entry qualifications for the five major tournaments and events like the HSBC Women's World Championship. Players who hold ranking points but do not participate in tournaments for two years, or 104 weeks, are removed from the list. They must compete at least once during that period.
