In 2007 the 64-woman field was selected as follows:
The top-30 players on Rolex Rankings List through the U.S. Women's Open (July 2, 2007) who commit to play in the event. (Numbers 31 and higher on the Rolex Ranking List were not eligible even if one of the top 30 did not commit.)
The top-30 players on the Official Money List through the U.S. Women's Open (July 2, 2007), who commit to play in the event.
Two sponsor exemptions.
Only the number-one ranked player on the Ladies European Tour Order of Merit through the U.S. Women's Open (July 2, 2007), who commits to play in the event.
The defending champion, if not otherwise qualified.
Any spots remaining after the above criteria have been applied will be taken from the Official Money List through U.S. Women's Open (July 2, 2007), who commit to play in the event, to complete the field.
