Rolex Rankings Movers of the Year - Part 1

Now that we have completed about 1/3 of the LPGA season, I would like to look at the players that have made the biggest leaps, and taken the biggest falls in the Rolex Rankings this year.

The Rolex Rankings system awards points to players based on an accumulated 104-week "rolling" period, with the points awarded in the most recent 13-week period carrying a stronger value.
A player is then ranked according to her average points per tournament, as determined by dividing her total number of points by the number of eligible tournaments played during the 104-week period. A minimum divisor (35) is also used.

I have gone back to the first Rolex Rankings of the year and compared them to the current rankings. The only requirement for my list is that a player must have been ranked in the top 100 at the start of the year, or be in the top 100 now.

The Year's Biggest Winners:

1- Ariya Jutanugarn - 0.54 to 3.98 = Gain of 3.44 (moved from #236 to #18)
2- Lizette Salas - 1.47 to 3.81 = Gain of 2.34 (move 89 to 20)
3- Inbee Park - 8.03 to 10.19 = Gain of 2.16 (move 4 to 1)
4- Beatriz Recari - 1.89 to 3.24 = Gain of 1.35 (move 57 to 26)
5- Suzann Pettersen - 7.04 to 8.31 = Gain of 1.27 (move 6 to 3)
6- Lydia Ko - 2.40 to 3.56 = Gain of 1.16 (move 43 to 22)
7- Carlotta Ciganda - 2.13 to 3.24 = Gain of 1.11 (move 50 to 27)
8- Jessica Korda - 1.61 to 2.41 = Gain of 0.80 (move 78 to 46)
9- Stacy Lewis - 8.39 to 9.10 = Gain of 0.71 (move 3 to 2)
10- Jodie Ewart Shadoff - 1.00 to 1.51 = Gain of  0.51 (move from 137 to 72)
11- Gerina Piller - 1.31 to 1.77 = Gain of 0.46 (move 95-46)

The Year's Biggest Losers:

1- Yani Tseng - 10.58 to 7.69 = Loss of 2.89 (move #1 to #5)
2- Mika Miyazato - 6.54 to 4.44 = Loss of 2.10 (move 10 to 13)
3- Sun Ju Ahn - 5.15 to 3.47 = Loss of 1.68 (move 13 to 23)
4- Brittany Lincicome - 4.60 to 3.23 = Loss of 1.37 (move 18 to 28)
5- Chi Arimura - 4.53 to 3.19 = Loss of 1.24 (move 20 to 29)
6- Shanshan Feng - 7.27 to 6.07 = Loss of 1.20 (move 5 to 8)
7- Ji-Hee Lee - 3.79 to 2.60 = Loss of 1.19 (move 25-39)
8- Sun Young Yoo - 4.08 to 2.99 = Loss of 1.09 (move 23-33)
9- Amy Yang - 5.01 to 3.98 = Loss of 1.03 (move 15-17)
10- Brittany Lang - 3.51 to 2.48 = Loss of 1.03 (move 29 to 42)
11- Azahara Munoz - 4.98 to 4.01 = Loss of 0.97 (move 16 to 16)
12- Na Yeon Choi - 9.08 to 8.12 = Loss of 0.96 (move 2 to 4)

Other Tidbits:
Ariya Jutanugarn, who is not an LPGA member, has played 4 LPGA tournaments this year and finished 2nd, 4th, 3rd, and tied for 3rd.

Titleholders Update:
Cristie Kerr, Ihlee Lee, and Gerina Piller are the latest to qualify. Azahara Munoz is the highest ranked player on the priority list, not yet qualified.

Rolex Movers of the Week:
Suzann Pettersen moved from #5 to #3. Cristie Kerr sneaks into the top ten by moving up 2 places to #10.
Ariya Jutanugarn continues her surge by moving from #23 to #18.
On the down side, Yani Tseng drops another spot to #5.

  1. Very interesting, Tony. Thank you. What I notice the most is the relative difference depending where each player is on the rankings list. Lizette gains 2.34 points and moves 69 spots. Inbee gains 2.16 points and moves 3 spots. Granted Inbee is moved to #1, but still it demonstrates the difficulty in entering the true elite level of players in the world. Week in, week out the top ladies produce.

    1. Glen, I love playing with numbers and actually did (for myself), an analization of the movement within sections of the rankings. It's nice to see someone who not only reads this but does his own analysis. Your observations are always right on the mark.

  2. Your top 10 movers are consistent with current form on the LPGA. As Glen said, the winners are the players we see on the leader board week in and week out. All of your top ten have had fantastic results in 2013 which also demonstrates the recent 13 week weighting.

    Just curious, that's a lot of numbers to process. Do you keep this on a spreadsheet?

    Keep the good stuff coming.

  4. educative and entertaining, and let me inform you. you might have hit the nail on the
    head. Your idea is outstanding; the problem is something that not sufficient people are speaking intelligently about. I am very joyful that I stumbled across this in my seek for
    something referring to this.
