Now the 15th non-member to ever win an LPGA event, Seo gets another chance this week at the Kraft Nabisco Championship. She qualified for the first major of the year based on her number one ranking on the KLPGA money list in 2009.
Also seeing significant jumps on the Rolex Rankings were Inbee Park and Morgan Pressel due to their top-10 finishes at the KIA CLASSIC Presented by J Golf. Inbee Park's impressive final-round score of 65 gave her a second-place finish in the event and moved her 11 spots higher in the Rolex Rankings to 27th. Morgan Pressel jumped five spots to 21st in the Rolex Rankings.
The Rolex Rankings (www.rolexrankings.com) are sanctioned by the five major women's professional golf tours: the LPGA; Ladies European Tour (LET); Ladies Professional Golfers' Association of Japan (LPGA of Japan); Korea Ladies Professional Golf Association (KLPGA); Australian Ladies Professional Golf (ALPG); as well as the Ladies Golf Union (LGU), which administers the RICOH Women's British Open.
The Rolex Ranking Board and Technical committee recently agreed on several modifications to the Strength of Field calculations which include: an increase in the World Points factor from 200 to 400; a minimum value of 100 for Strength of Field for all Tours, except the Duramed FUTURES Tour; and the implementation of a true Strength of Field calculation for Duramed FUTURES Tour events, rather than the fixed points ratio of the past.
The Rolex Rankings are the only women's world rankings that incorporate player performances from the five major tours and the Duramed FUTURES Tour, the official developmental tour of the LPGA.
