Wimbledon Seedings - mightyjeditribble - 18-Mar-2017 08:51 PM

(Edited to correct the formula.)

There has been some discussion about 2017 Wimbledon seedings. In particular, the question was raised whether Federer will achieve a top 4 seeding.

It is really far too early, and there are too many unknowns. Still, we can take a look at the points that we already know will be added.

The formula is as follows: Take the points as current ahead of Wimbledon, add the previous 12 months grass court results again (i.e., 2017 warm-ups + 2016 Wimbledon), and 75% of the best result of the previous 12 months (2016 warm-ups and 2015 SW19).

Fed has 2015 Wimbledon F (1200), 2016 Stuttgart, Halle, Wimbledon SF (90/180/720).

75% of 1200=900
So points to be added are 1620 + grass-court results from 2017.

So Fed will indeed have a significant advantage through the seeding system. Apart from Murray and Djokovic, there would seem to be only Raonic at a similar level.

He has 2015 Wimbledon R3 (90) 2016 Queens F (300), Wimbledon F (1200).
So he gets an extra 1425 + grass-court warm-ups 2017 for the seedings.

So we see that Fed is ahead even of Raonic on the extra grass-court points. If Fed wins IW, he will be almost equal with Raonic on current ranking points. Nishikori and Stan are higher, but have almost nothing in grass-court results to be added for the formula (Nishikori has 2016 R16, Wawrinka 2015 QF, adding 180/270 points; very little otherwise).

Currently, Fed's deficit in the rankings behind the top 3-6:
Wawrinka: 1800 (2200 if Stan wins IW, 1400 if Fed does);
Nishikori: 825 (425 if Fed wins IW);
Raonic: 575 (175 if Fed wins IW);
Nadal: 240 (Roger overtakes Rafa if he wins IW).

A lot can still happen between now and Wimbledon, but as things stand, a top 4 seeding for Federer no longer seems entirely fanciful, particularly if he wins the IW title.

The formula you are using is wrong.

The points won on grass beginning from 2016 Wimbledon will be added. From the 12 months before that time, they will pick the best result of a player on grass and add 50% of that.

So, Fed's addition will be 600 (half of 1200) + 720 + 2017 Stuttgart pts + 2017 Halle pts.

Actually, we were both wrong.

It's 75% not 50%.

Quote:While the seeds are still the top 32 players according to rankings, the seeding order is determined using the formula: ATP Entry System Position points + 100% points earned for all grass court tournaments in the past 12 months + 75% points earned for the best grass court tournament in the 12 months before that.,_Wimbledon

Do it, for the top 10 folks.

Total grass-court points added for Wimbledon seedings in 2017, minus the 2017 warm-ups.
Murray 2540
Djokovic 1590
Wawrinka 315
Raonic 1425
Nishikori 213.75
Federer 1620
Nadal 33.75
Cilic 630
Thiem 232.5
Tsonga 427.5

So Murray unsurprisingly with the most added points; Fed is second, after Djokovic (thanks to his 2015 win) and Raonic.

It would be fun to have a "race to SW19" ranking taking these points into account. But for that you need to have a good database.

Instead, let's add the additional points above to the corresponding players' points total as they are now (or rather, as they will stand tomorrow after Fed's IW win). It doesn't mean very much, but can maybe give an impression of where things stand.

Murray 14545
Djokovic 10505
Raonic 6155
Wawrinka 6020
Federer 5925
Nishikori 4694
Nadal 4180
Cilic 4095
Tsonga 3737
Thiem 3652

So, where things stand, things are quite close between Raonic, Wawrinka and Fed. Clearly a top 4 seeding for Roger is now very much possible. One more good tournament before the grass-court season, and decent results in the warm-ups, may be enough to make it a reality.

Coincidentally, with Murray and Djokovic absent, Fed will be #4 seed in Miami.

RE: Wimbledon Seedings - mightyjeditribble - 20-Mar-2017 08:19 AM

Because I apparently have nothing better to do, I have tried to create the numbers for the "Race to Wimbledon 2017" for the current top 10. I have done this by adding up the clay-court and grass-court points from 2016 for each of these players, so these numbers should be taken with a grain of salt as there are probably some errors. It also doesn't take into account matters such as non-countable tournaments that might become countable when clay-court results are removed etc. But hopefully it is robust enough to give a relatively accurate picture.

So here are the standings of the "Wimbledon seedings race" going into Miami:

Murray 10840
Djokovic 5895
Federer 5385
Wawrinka 4990
Raonic 4840
Cilic 3795
Tsonga 3152.5
Nishikori 3098.75
Nadal 2038.75
Thiem 1867.5

So Fed is in a good position at the moment, but of course Miami, the upcoming clay-court season results and the grass-court warm-ups (counting twice) will be added to these totals.

So it will be interesting to see what this looks like after Miami. To make it easier to keep the points updated; according to my calculations, the following are the totals of the 2016 results from Wimbledon onwards, plus the extra points used for the seedings (calculated above). Until the beginning of the grass season, the "race to Wimbledon" points can be computed by adding the number below to the 2017 race total.

Murray 10000
Djokovic 5420
Wawrinka 3580
Raonic 4240
Nishikori 2438.75
Federer 2340
Nadal 403.75
Cilic 3470
Thiem 737.5
Tsonga 1897.5
