Pak suffered a first-round loss this week to rookie Azahara Munoz. Munoz improved four places to No. 86. Also dipping in the rankings this week are Brittany Lang and Pat Hurst. Both players dropped three places to sit at No. 32 and No. 59, respectively.

On the Japan LPGA, former LPGA member Na Ri Kim catapulted herself up the rankings with a 2nd place finish at the Chukyo TV Bridgestone Ladies Open. She jumped 53 spots to break into the top-100 for the first time in her career. She sits at No. 88.

The Rolex Rankings ( 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.
