The Rolex world No. 1 ranking is up for grabs yet again at the Evian Championship this week.
The top five in the world all have a chance to leave France with the top ranking.
With so many world-ranking points up for grabs, Sung Hyun Park has some work to do to extend her reign as No. 1 to a fifth consecutive week.
No. 2 Ariya Jutanugarn is just .297 average world ranking points behind Park. She can get back to No. 1 for the third time in her career with a finish of fourth or better this week, depending on what Park and the other players among the top five do.
No. 3 So Yeon Ryu, No. 4 Inbee Park and No. 5 Lexi Thompson can also ascend to the top spot.
Ryu and Inbee Park have both reigned as No. 1s before. Thompson is seeking to move to the top of the world rankings for the first time in her career. She has a chance to become the seventh different player to hold the No. 1 ranking over the last 15 months, but she has to win to ascend.
