Stay tuned for more Rolex Rankings shake-ups when the world’s best compete at the Tres Marias Championship in Morelia, Mexico, April 29-May 2. Rolex Rankings No. 1 Lorena Ochoa will compete to defend her title and solidify her spot atop the 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.
