French Open Odds Update: Quarterfinals

The draw looked odd this morning — Andy Murray and Viktor Troicki were still in the fourth round, while Novak Djokovic was safely in the semis following Fabio Fognini’s withdrawal. (Djokovic’s odds of advancing didn’t change much with Fognini’s withdrawal!)

Now that things are back to normal, we can update the odds. My rankings make Novak the 2-1 favorite to reach the final over Federer–probably a little optimistic for Roger, but you have to admit, the Swiss has looked surprisingly good this week. Largely thanks to Djokovic, there’s a 60% chance that the tournament winner comes from the bottom half.

Here are the odds for the remaining players:

Player                  SF      F      W  
(1)Rafael Nadal      68.9%  49.6%  24.9%  
(5)Robin Soderling   31.1%  17.1%   5.1%  
(4)Andy Murray       86.8%  32.1%  10.0%  
Juan Ignacio Chela   13.2%   1.1%   0.1%  
(3)Roger Federer    100.0%  33.1%  16.2%  
(2)Novak Djokovic   100.0%  66.9%  43.8% 

The French Open’s New Balls

Italian translation at settesei.it

Much has been made over the new balls at Roland Garros this year–players have complained that they are lighter, heavier, that they bounce differently.  As far as bounce and spin is concerned, there isn’t much we can glean from the available data.  But we can take a broad look at server dominance to get a sense of how the French is playing this year.

Several months ago, I looked at most of the ATP-level matches from 2010, and determined that the server wins points on different surfaces at the following rates:

  • Clay: 61.5%
  • Hard: 63.7%
  • Grass: 65.9%

The gaps between those numbers may not look very big, but they represent a major indicator in the differences between surfaces.  If the gap between clay and hard is 2.2%, then 2.2% must be a pretty big deal!

I’ve also determined the following regarding ace rates–again, using 2010 data.  “Ace rate” is simply the percentage of serves that are aces:

  • Clay: 5.5%
  • Hard: 8.5%
  • Grass: 10.5%

Now that’s a big difference.

Roland Garros

What about the French?  Taking the 2010 event as a whole, players won 62.4% of service points, and served aces 6.6% of the time.  Thus, I think it’s reasonable to conclude that the courts at RG last year played faster than most other clay-court ATP events.  Weather and–you guessed it–other equipment, such as balls, can also make a difference.

This year, 112 of the 127 men’s matches have already been played, including over 17,000 points, so I think it’s safe to start drawing conclusions.  This year, servers are only winning 62.0% of points–roughly halfway between the clay-court average and the results from last year’s “fast” RG.  More dramatically, players are only scoring aces on 5.6% of points, well below last year’s figure at the French.

I can’t shed any light on the specific quirks shown by the new balls, but for whatever reason, the French is playing more like an average clay-court event than it did last year.

French Open Odds Update: 4th Round

With Juan Martin del Potro out of the way, Novak Djokovic is once again the odds-on favorite to win the French Open. His chances of winning are up to 38.7%, while Rafael Nadal’s haven’t budged much, now sitting at 25.8%.

Djokovic seems set to cruise into the semifinals, at least. Tomorrow he’ll face Richard Gasquet, and then in the quarters it gets even easier, with either Fabio Fognini or Albert Montanes. Things have worked out nicely for another Serbian, as well. Viktor Troicki will play Andy Murray–not the easiest draw, of course, but made easier by Murray’s ankle-twisting today. And whoever comes out of that match should be able to reach a semifinal date with Nadal, as the next opponent will be either Alejandro Falla or Juan Ignacio Chela.

French Open Odds Update: 3rd Round

Three-quarters of the field has been eliminated, and we’re left with 32 men standing. Who’s left: 6 of the top 8, 13 of the top 16, and 21 of the top 32. All the wild cards and lucky losers are out (though Marsel Ilhan went down fighting!) but of the 11 unseeded players still in the draw, an amazing six are qualifiers.

In the odds below, you might notice an interesting twist. Suddenly, Nadal is the favorite! As Juan Martin del Potro has taken care of business and ensured a third-round clash with Novak Djokovic, Djokovic’s chances of reaching each successive round have decreased. But the men in Nadal’s section have done him favors–especially qualifier Antonio Veic, who knocked out Nikolay Davydenko today. The Russian is always a threat, but I don’t think we can say the same about Veic.

Nadal’s chances are up to 26.9%, while Djokovic’s have fallen to 25.8%. Of course, both of those numbers are far beyond anyone else in the field. On the other end, qualifiers Veic and Steve Darcis have the smallest chances of winning the title–they each won it all only once per 50,000 simulations. The qualifier with the best chance is Lukasz Kubot, who is about 15 times more likely than Darcis to take home his first grand slam championship.

French Open Odds Update: 2nd round

64 men are out of the draw, with the usual handful of first-round surprises. Murray’s quarter has gotten even weaker with the early exit of Nicolas Almagro, while Berdych’s 1st-round defeat doesn’t affect Djokovic’s odds much.

Oddly enough, there are more very-lopsided matchups in the 2nd round than there were in the first. Nadal, del Potro, and Djokovic all have a 93% chance of advancing to the third round, while Federer is above 91%. The only two ultra-tight matchups this round are in Melzer’s section, where Kevin Anderson and Juan Ignacio Chela are close to dead even, and Carlos Berlocq is roughly equal with qualifer Lukasz Kubot.

Remarkably, 8 of the 16 qualifiers got through to the second round, while 2 of the 6 lucky losers did so. 3 of the 8 wild cards advanced, though one of those was a foregone conclusion, as two WCs faced off in the first round.

Here are the odds for the rest of the tournament:

Winners and Losers in the French Open Draw

Yesterday I offered a full breakdown of the French Open draw, with each player’s chances of advancing to each of several rounds.  In any draw of this kind, there are winners and losers, thanks to the luck of the … well, draw.

In a 128-player field seeded in the manner that Grand Slams are seeded, there are nearly 100,000 permutations of the draw.  The vast majority don’t matter — for instance, if you swapped Thiemo de Bakker and John Isner so that de Bakker played Nadal in the first round and Isner played Djokovic in the first round (instead of vice versa), no one’s chances of winning the title would change much.

But, of course, many of the possible permutations would matter a whole lot.  Just ask de Bakker or Isner!  Imagine how much better it would be for Isner to have a first round draw against, say, Yen-Hsun Lu, followed by a probable second-rounder against Sergiy Stakhovsky.  In fact, that’s Kei Nishikori’s draw, and in that sense, Nishikori was very lucky that the chips fell where they did.

Stepping back

In my previous draw simulations–like the one I published yesterday–I took the actual bracket as a given.  To generate the probabilities you see in yesterday’s chart, I had a computer program “play” the tournament 100,000 times, each time pitting Isner against Nadal in the first round, then the winner of that match against the winner of Giraldo/Andujar, and so on.

There’s a different way we could approach this.  Instead of starting the simulation from the point at which the draw is set, we could start from the point at which the field was set and seeded.  At that point, Isner would know that he is not seeded–and thus, that he would probably face a seed in the first or second round–but not which higher-ranked player he would face.

So, instead of 100,000 simulations of the actual French Open bracket, we can do 100,000 simulations of the draw itself, followed by simulating each ensuing bracket.  Sometimes, Isner draws Nadal, sometimes he draws Hanescu, and so on.

Measuring draw implications

A good way to gauge a player’s overall chances at a tournament is his predicted prize money.  Most players don’t have a significant chance of winning most tournaments (especially slams), so to compare Giraldo’s 0.01% chance of winning the title with Cuevas’s 0.02% chance doesn’t tell us much.  But if we consider the possibility that each player reaches each round, we can estimate that Giraldo will take home E24,600, while Cuevas will collect E29,500.  These numbers represent an average of the first-round prize money, second-round prize money, and so on, weighted by the probability that the player will reach each of those stages.

With this metric, we can compare the implications of the actual draw with the implications of the randomized draw, in which, for instance, Nadal could play any one of the 96 unseeded players in the first round.

Let’s compare the two outcomes in an extreme case.  As we’ve seen, the draw was not kind to John Isner.  My algorithm gives him a 12% chance of reaching the second round, and less than a 1% chance of reaching the semis.  Crunch the numbers, and you have predicted prize money of E22,700.  When you randomize the draw and he no longer has to beat Nadal in the first round, his chances of reaching the second round leap to 60%, and he has a 2% shot at a semifinal berth.  Predicted prize money: E40,100.

As it turns out, Isner is our biggest loser.  His predicted prize money fell more than 40% between the beginning and end of the draw ceremony.  What’s remarkable is that the next four players on the list all come from the same 1/16th of the draw–you guessed it, Djokovic’s section.

The draw effect on Thiemo de Bakker is similar to that on Isner–it doesn’t get any worse than drawing Djokovic in the first round.  Next on the list are Ernests Gulbis, Ivo Karlovic, and Juan Martin del Potro.  Karlovic and Gulbis not only have the misfortune of drawing Delpo in the first two rounds, but if by some chance they get past the Argentine, then they face Djokovic!  Each of those players lost more than 30% of their predicted prize money through the vagaries of the draw.

Del Potro is an interesting case.  As is, his predicted prize money is E184,600.  Before the draw was set, he could expect E266,000.  The biggest difference, of course, is his chance of reaching the round of 16.  In real life, he’ll need to beat Djokovic to get there, and he has a 30% chance of getting that far.  Before the bracket was drawn, the expectation was that he’d need only to defeat someone in the top 16 (or possibly, a player who had upset someone in the top 16).  He had a 63% chance of doing so.

Winners

Naturally, if there are so many players whose predicted prize money decreased, some players must have benefited from the way the draw played out.

One of the biggest winners was Andy Murray.  As we’ve seen, plenty of dangerous players are concentrated in Djokovic’s quarter; in fact, Djokovic, Nadal, and Federer were all hurt by the draw.  But Murray’s draw boosted his predicted prize money from E191,700 to E240,800.  He’ll face a qualifier or lucky loser in each of the first two rounds, then no one more challenging than Milos Raonic in the third.  Next would be Dolgopolov or Troicki–no walkovers, but compare that to Nadal’s possible fourth-rounder of Verdasco, and you see how the breaks went in Andy’s favor.

Murray’s quarter is the softest of the four, and other men benefit even more.  In fact, the two players whose chances the draw boosted the most are Nicholas Almagro and Jurgen Melzer, who will likely play in the fourth round for a matchup with Murray in the quarters.  Almagro, Melzer, and Juan Ignacio Chela (also in this section) all saw their predicted prize money jump by more than 40%.  For example, Almagro went from E76,100 to E112,400–and more than doubled his chances of winning the title from 0.6% to 1.3%–by landing where he did in the bracket.

Regardless of any player’s specific placement, the best man will probably win.  But the draw certainly has a say in how tricky the route to the title will be.

French Open Predictions

The qualifying rounds are over, and the draw is set.  I plugged the full 128-man bracket into my simulator, combined it with my most recent clay-specific rankings, and the full results are below.

A few quick hits on the draw and the simulation results:

  • All of the top three players have challenging draws.  Nadal faces Isner in the first, then possibly Davydenko in the third, Verdasco in the 4th, and Soderling in the quarters.  Federer drew Feliciano Lopez in the first.  And Djokovic got the worst possible outcome: Del Potro in the third.  There probably isn’t an upset there, but if anybody’s going to take Novak out before the final, Delpo’s my bet.
  • There are eight Americans in the draw.  The odds that a US player–any US player–wins the tourney is 0.83%.  The odds that all eight are knocked out in the first round?  0.85%.  Only Fish and Sweeting are favorites in their opening matches.
  • On the country-by-country theme, France has 20 men in the main draw, with a likelihood of just under 4% that a Frenchmen will win the title.  Spain has 14, for a total title shot of 26.4% — just below Djokovic’s chances by himself.
  • Some tight matchups in the first round: Fognini/Istomin, Hewitt/Montanes, Brands/Kukushkin, Paire/Hanescu (home court advantage flips that in Paire’s favor), Teixeira/Millot (two wild cards), Tomic/Berlocq, Gimeno-Traver/Haase, and Tursunov/Malisse.
  • The most lopsided first-rounder–according to the numbers–is Djokovic vs. de Bakker, followed by Andy Murray vs. Eric Prodon, the only two where my system gives the favorite a 90% chance of advancing.  There are plenty in the high 80’s, as well.

Updated Clay Rankings and Roland Garros Qualifying Threats

Last week, I wrote up a piece for ESPN.com that is supposed to run today.  I’ll post a link as soon as it’s up.  The article uses my ranking system to order the top players on clay, and of course, between last week’s deadline and this week’s publication, the ranking changed.

Here are some gainers and losers in my system heading into the French:

  • Djokovic is #1.  Now that he’s beaten Nadal twice in a row, it isn’t even close.  In Rome, my system gave Rafa a slight edge; if they meet in the French Open final, it thinks Novak has a 58% chance of winning.  Oddly enough, that percentage is a little stronger on clay now than it is on hard courts, though of course Djokovic is favored on all surfaces.
  • Murray is at #6, but basically tied for #5 with Soderling.  Coming into the clay season, he was outside the top ten on the surface; a couple of good results and he’s moving up the list.  If anything, his ranking underrates him, as we saw in his match against Djokovic last week.
  • Richard Gasquet is #8.  He’s been going deep almost every week, and he has lost only to the best.  If I were a top-8 player, I wouldn’t want to see him in my quarter of the draw.
  • A trio of disappointment: Mikhail Youzhny, Alexandr Dolgopolov, and Juan Monaco.  Three very different players, none of whom are posting any results to be proud of.  Dolgo, especially, should do better–this could have been his season to break through. They sit at #33, #37, and #41, respectively.
Here are a handful of players who do well in my ranking system and are fighting through Roland Garros qualifying this week:
  • #60 Thomas Schoorel — he’s been a beast on the European challenger circuit lately, and he could make trouble for players who have yet to face the big serving of this tall lefty.
  • #66 Ryan Harrison
  • #71 Ilya Marchenko
  • #73 Andrey Kuznetsov (he’ll play Marchenko in the second round)
  • #87 Horacio Zeballos — I’ve mostly given up hope on the Argentine breaking through, but you never know.
  • All between #90 and #100, all into the second round: Facundo Bagnis, Evgeny Donskoy, Cedrik-Marcel Stebe, and Federico del Bonis.
As soon as the qualifiers are placed in the main draw, I’ll run a simulation for the entire tournament.

Breaking In and Breaking Through

Yesterday we looked at players who broke into the top 100 when they were teenagers.  As expected, those guys generally went on to great success–17 of the last 25 eventually reached the top 10, and at least two more may still do so.

We can gain a broader perspective by analyzing more than just teenagers.  If a 19-year-old entering the top 100 is likely to become a top-10 player, what chances do 22-year-olds or 26-year-olds have?  By examining a few decades of the ATP ranking system, we can begin to answer these questions.

I used a sample of 590 players–everyone who entered the top 100 between 1980 and 2005.  (It’s possible that a few recent players will continue to improve, but the vast majority of players get close to their peak within five years, so 2005 seems like  a reasonable cutoff date.)  A bit less than half of those 590 broke into the top 100 between the ages of 20 and 22, about a third were older, and the remainder were teenagers.

As you can see in the table below, there is a clear correlation between breaking into the top 100 at an early age and reaching the higher echelons of the pro game.  In the last 30 years, only one #1-ranked player (Pat Rafter) hadn’t reached the top 100 as a teenager, and he made it into the top 100 when he was 20.  Almost every eventual top-10 player had broken into the top 100 by age 21.

Age  Players  Top50  Top20  Top10  Top5  Top1
16         4   100%   100%   100%   75%   50%
17        16   100%    88%    69%   56%   38%
18        38    87%    76%    61%   34%   11%
19        61    89%    48%    41%   20%    8%
20        88    86%    48%    25%   13%    1%
21        99    63%    22%    12%    7%    0%
22        83    47%     8%     5%    2%    0%
23        61    44%    16%     3%    0%    0%
24        62    31%     3%     0%    0%    0%
25        32    25%     0%     0%    0%    0%
26        10    60%    10%     0%    0%    0%
27        16    31%     0%     0%    0%    0%
28        10    20%     0%     0%    0%    0%
29+       10     0%     0%     0%    0%    0%

It’s not entirely clear that these trends are consistent from decade to decade–yesterday, I noted that fewer teenagers had reached the top 100 in the last ten years or so.  It’s possible that as the quality of the game improves and a larger amount of training is necessary to prepare for the pro tour, there will be fewer prodigies like Nadal, who broke in at age 16, and Richard Gasquet, who arrived as a 17-year-old.

But even if the ages shift by a year or two, the overall conclusions should hold.  The older you are when you arrive in the top 100, the less likely it is that you will advance considerably further.

One obvious application of this data is to make predictions regarding players as they enter the top 100.  The last two men to break in are Benoit Paire (age 22) and Matthias Bachinger (age 24).  Paire is still young enough to have an outside shot at the top 10; Bachinger will have a hard time doing much better than #50.  Another recent newbie is Go Soeda, a 26-year-old.  To find someone who made a top-20 success out of so late a breakthrough, you have to go back to Steve Denton in the mid-80s.

Another way to use this information is to find top prospects among current players.  Among active tour pros, the four men who broke in at the youngest ages are Nadal, Gasquet, Juan Martin del Potro, and Novak Djokovic.  The next two might surprise you: Kei Nishikori and Donald Young.  Nishikori has only now recovered from battles with injury–perhaps he will start to make good on his promise.  Young may be a unique case–were it not for his many, many wildcards, he would not have reached the top 100 so early.

Another surprise is the active player with the 10th-youngest age-of-reaching-100: Evgeny Korolev.  The Russian has also struggled with injury, but he did crack the top 50 last year.

The more oft-mentioned “prospects” are a little further down the list.  Grigor Dimitrov broke in at 19.7 years of age, while Milos Raonic appeared just after his 20th birthday–a few days older than the first appearance of Mischa Zverev.  Alexander Dolgopolov is further down than you might expect, having broken in at age 21.3, while Ryan Sweeting didn’t get there until 23.5.

Of course, “age of first appearance in the top 100” is just one metric, and it doesn’t tell the whole story.  Perhaps players who spend several years in college account for that blip in the table at age 23–John Isner, for instance, didn’t reach the top 100 until he was nearly 23, and he has already hit a peak ranking of #18.  The metric might also underrate the chances of those who suffer prolonged injury at an early age–perhaps if Nishikori had lost his two years to injury one season sooner, he would have only recently reached the top 100 with the same skills and potential.

Warts and all, this angle is a good reminder of why we should keep a close eye on youngsters in the futures and challenger tours–the latest, greatest 23-year-old is almost guaranteed not to be the future of the sport.
