Rolex Rankings move of the week: Miyazato moves up four spots with win

Japanese star Ai Miyazato picked up her second career victory and moved up four spots in the Rolex Rankings with her win at the season-opening Honda PTT LPGA Thailand at Siam Country Club in Chonburi, Thailand this past weekend. Miyazato is now ranked fourth in the world, the highest ranking of her career.

The fifth-year player recorded a career-low 63, also a tournament record, in the final round to win by one stroke over six-time Tour winner Suzann Pettersen. Miyazato (21-under-par 267) was 10-under-par in her final 16 holes, and chipped-in for birdie at 18 to clinch her first victory since the 2009 Evian Masters Presented by Societe Generale.

Fellow Japanese player Momoko Ueda made the jump into the top-25 of this week's Rolex Rankings after finishing tied for sixth in Thailand. Ueda, now ranked 25th, is in her third year on the LPGA Tour and looks to become a Rolex First-Time Winner in 2010. In 2007 as a non-member, Ueda won the Mizuno Classic in her homeland of Japan.

As global as the LPGA Tour is and continues to become, the top-7 players in this week's Rolex Rankings represent a different country.

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.
