Rolex Rankings Movers of the Year 2015 - Final

As we wait for the 2016 season to begin (we are about a month away), it gives me a little time to look back at the players that made the biggest moves in the Rolex Rankings in 2015.

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 requirements for my list are: A player must have been ranked in the top 100 at the start of the year, or be in the top 100 now. 


Brooke Henderson was the biggest mover of 2015

  1. Always an interesting collection, Tony. A changing of the guard of sorts. I am doubtful I will see the original Seoul Sister again. Other standards such as Matthew and Webb are nearing the end. On the other hand, I look forward to Ko and Henderson for years to come. Also Alison Lee and Minjee Lee. No need to mention my approval of Lexi continuing her rise, you are well aware of that sir.

  2. Appreciate the effort and time you spent to give us your Rolex Movers. The Rolex World Ranking calculations are still a bit nebulous to me, especially the 91 decrement calculations. Anyway, it seems to be more difficult to maintain and move up in ranking once a player reaches 50+ events (25+ events/yr). That could be seen with Stacy and it might affect Lydia in 2016 as she started 2015 with 43 and is now at 53. I was also surprised by the total points gained stats so below are 20 for 2015. Total points lost were too :( ...

    01- Lydia Ko: events 43 > 53, points 415.38 > 624.16 = +208.78 (whoa!)
    02- Sei Young Kim: events 50 > 54, points 122.94 > 315.42 = +192.48
    03- In Gee Chun: events 49 > 59, points 170.91 > 313.13 = +142.22
    04- Sung Hyun Park: events 28 > 53, points 23.55 > 156.13 = +132.58
    05- Brooke M. Henderson: events 07 > 23, points 17.69 > 142.90 = +125.21
    06- Minjee Lee: events 18 > 42, points 50.62 > 171.26 = +120.64
    07- Alison Lee: events 01 > 25, points 3.11 > 113.99 = +110.88
    08- Bo-Mee Lee: events 62 > 63, points 161.07 > 269.23 = +108.16
    09- Amy Yang: events 44 > 45, points 146.24 > 242.29 = +96.05
    10- Lexi Thompson: events 49 > 49, points 260.29 > 346.48 = +86.19
    11- Ha-Na Jang: events 52 > 57, points 177.42 > 260.47 = +83.05
    12- Jin-Young Ko: events 29 > 54, points 84.78 > 165.61 = +80.83
    13- Candie Kung: events 51 > 52, points 38.62 > 105.84 = +67.22
    14- Cristie Kerr: events 46 > 50, points 193.82 > 256.35 = +62.53
    15- Morgan Pressel: events 54 > 56, points 116.59 > 178.73 = +62.14
    16- Teresa Lu: events 60 > 59, points 162.00 > 221.51 = +59.51
    17- Ji-Hee Lee: events 58 > 58, points 63.52 > 121.16 = +57.64
    18- Yani Tseng: events 49 > 52, points 66.72 > 123.25 = +56.53
    19- Mi Hyang Lee: events 48 > 61, points 97.22 > 151.47 = +54.25
    20- Xiyu Lin: events 42 > 56, points 58.33 > 112.26 = +53.93

    Cheers and Happy New Year!

    1. Ranking them by total points makes for an interesting comparison but that is not what is used to determine the final Rolex rankings. The total points have to be divided by the number of tournaments played or the player that plays the most tournaments would have a huge advantage. Average points per tournament is what is used to determine the ranking. That is what I used in my study.

    2. No matter how you look at it it shows just how hard it's going to be for anyone else besides Inbee or Lydia (5 wins 2015) to not be RR #1 all season. Should either get off to a hot start the rest can only look to next year maybe with the exception of Brooke with a divisor of 35 who would also have to have many wins this season to come close and Inbee and Lydia would have to have a very poor year...Just can't see that happening. Even Stacy at #3 with her points retiring for wins 2 years ago would have to come back with a stellar year or am I wrong with this assumption....

  3. I guess this really puts Lydia Ko's consistency in real perspective. Inbee Park gained in points, but still dropped to #2 in the rankings. That can only happen with a superlative #1.

  4. Always enjoy your posts, Tony. I'm waiting to see what the new LPGA priority list will look like for the start of the 2016 season. It should be out soon. The first two events are limited fields- 120 players-(due to daylight). So a few of the players who earned full status cards at Q School may not get into them. I remember last year that Nannette Hill and Kelly Shon, who both did well at Q School, did not make it into the Coates event in Ocala. They were 1st and second alternates at the Coates event. A few others below them at Q School also did not get in. Happy Year Year! Pars and birdies!

    1. Yes, I am waiting for the new priority list myself. I hope it comes out sooner than later as I need it to set up all my sheets for next year's statistics. Have a great New Year and thanks for everything. Hope to see you at an event soon.

      PS: Will be doing Shoprite, US Open, International Crown, and Canadian Open.

  5. Thanks again, Tony, for the captivating analysis ! Pressel's resurgence, along w Henderson's fearless burst of talent and enthusiasm, were Season highlights! I'm looking for Charley Hull to have a Big Year in 2016. It will also be interesting to see what impact the Olympics have on Player performances. Happy New Year !!
