The Greatest Upset in Sports Recency

Last night, Lukas Rosol shocked the tennis world by beating Rafael Nadal.  Immediately, the verdict was in: One of the greatest (the greatest?) upsets of all time.  Completely unthinkable.  Impossible to see coming.

And to a certain extent, that’s correct.  Nobody picked Rosol to beat Nadal; I’d be surprised if anyone went on the record forecasting that the Czech would win a single set.  But for all that, the superlatives have gone too far.  It’s one thing to predict that Djokovic/Nadal/Federer/whoever will win a certain match.  It’s another to make the broader claim that they will always beat opponents of a certain level.  The first claim is a sound one; the second is madness.

One way to look at this is a glance at the betting market.  For high-profile matches, punters and sportsbooks give us a good idea of the conventional wisdom going into a match.  Pre-match odds varied from (very roughly) 25:1 to 75:1.  Even if we go to an extreme and take odds of 100:1, that means that the market gave Rosol a 1% chance of victory.  A small chance, but far from a zero chance.

So, of course, Nadal should have gotten through to the third round–he probably should have gotten to the semifinals.  But with 1% underdogs at every step, every once in a while it’s not going to happen.  Consider that each of the top three play two matches against unseeded opponents at every slam.  That’s six opportunities at every slam for a greatest upset of all time.  The occasional first- or second-rounder doesn’t fit the bill, like Nadal-Isner at last year’s French, but later-round matches take their place, like Federer-Goffin last month.

Given 24 opportunities per year, there should be one such upset every four years.  That’s still newsworthy, but statistically speaking, it’s not the greatest upset in tennis history, it’s the greatest upset in very recent memory.  And that’s just counting slams.

No nobody

Part of the reason we overreact to these things is that our brains aren’t wired to think about small probabilities–it’s either likely or it’s not.  Another reason is the historically unprecedented dominance of the big three.

Contributing to the effect is something that Steve at Shank Tennis pointed out:  The media is inaccurately portraying Rosol as a “nobody.”  Sure, Rosol has never played a Wimbledon main draw before, and he’s beaten a top-20 opponent only once. But this is the third-ranked player from the Czech Republic, a man who has been in the top 101 for more than a year, peaking inside the top 70.  In any major team sport, a top-100 player is among the top five on his team; number 65 might make an all-star team.

When Donald Young beat Andy Murray, we were shocked, but not to the same extent–we all know about Young’s potential, and besides, American fans have been talking about him for years.  Even when Alex Bogomolov registered the same upset the following week, it was a recognizable name, also in part due to US wild cards and press attention.

Rather than dismissing yesterday’s match as a freak event involving a player who we’ll never hear from again, we’re better off to treat it as a sign of just how strong the back of the field is.  Rosol is not the only man outside of the top 50 with a thunderous game.  He’s not the only threat on tour who was never talked up as a junior.  And he’s certainly not going to be the last “journeyman” to register a high-profile upset over an “unbeatable” opponent.

The Aging Wimbledon Men’s Draw

Men’s tennis is getting older, and the drift toward middle age is evident at Wimbledon this week.

Of the 128 men in the main draw, 34 are at least 30 years old, while only two are in their teens.  This is just the latest step in a trend that has been evident for at least a decade.

The 34 30-somethings are not just a modern-day record–the number blows recent years out of the water.  Last year’s main draw had 24 30-somethings, and that was the highest such total since 1979.  Teenagers have been on the wane for years–there have only been two in the main draw in each of the last four years, but as recently as 2001, there were eight.  In several years in the late 80s and early 90s, there were more teenagers than 30-year-olds.

Whatever the explanation for this–and there are many possible ones–it’s clear that something is going on.  It takes longer than it ever has for a young rising star to establish himself on tour, and top players are able to stay healthy and competitive for as long as ever before.

2012 Wimbledon Men’s Projections

Here are my projections for this year’s Wimbledon men’s draw.  Djokovic is far and away the favorite now that we’ve moved away from clay.  Federer comes in a close third behind Nadal, helped in part by what is probably the easiest of the four quarters.

Intuitively, these numbers seem about right, especially for the top players.  But a few developments in the ATP recently have exposed some gaps in my ranking system.  Brian Baker’s quick ascendance has yet to do much for him in my system, in part because he hasn’t played very much top-level matches.  But after his performance in Nice, it seems wrong to give him less than a 35% chance against a journeyman like Rui Machado.

The other head-scratcher is Tommy Haas.  After winning Halle, my system isn’t giving him much credit, in large part because he’s 34. Since players start going downhill by age 26, a player’s rate of decline in his mid-30s would generally be staggering.   But, of course, most players are gone by then.  If someone like Haas is still playing (and winning), he probably isn’t subject to exactly the same laws.  Perhaps 34-year-olds on tour are rare enough that it isn’t all that important, but in this one case, it generates a forecast that doesn’t jibe with common sense.

Women’s odds were posted earlier today, and both forecasts will be updated throughout the tournament–I’ll post those links when I have them, probably mid-day Tuesday.

2012 Wimbledon Women’s Projections

Here are my forecasts for the Wimbledon women’s draw.  Despite Maria Sharapova’s performance at the French, my ranking system still has her third, behind both Serena and Azarenka.  Also, you might also be surprised by the significant chance I give Kim Clijsters.  While she hasn’t played much, she’s played well, and my system operates on the assumption that if someone takes the court, she is doing so fully healthy.  (Or, at least, as healthy as she’s been other times she took the court.)

If you’re interested in the rankings behind these forecasts, click here; for more background on the system, here.

I’ll post men’s odds later today, and the forecast will be updated throughout the tournament–I’ll post those links when I have them, probably mid-day Tuesday.

TennisAbstract.com, Supersized

I’m proud to announce the new, improved TennisAbstract.com, now with challengers, qualifiers, Davis Cup, and ATP matches back to 1968.

Previously, the site was limited to ATP-level matches back to 1991.  Now, the number of matches available has increased from 70,000 to 240,000, and the number of players with a page on the site has jumped from roughly 1,600 to almost 7,500.

Historical Matches

TA now includes every tour-level match ever played.  (In theory, anyway.)  You can check out Arthur Ashe’s career record, or his head-to-head with Rod Laver, or his performance in finals.  This dataset goes back to 1968.

Challengers

The biggest addition to the site is at the challenger level.  I’ve added nearly 90,000 challenger matches, which include all main-draw results since 1991.  Stats, including ace percentage and first serve percentage, are available for most challenger matches of the last five years.  For instance, see the epic 2011 Challenger season of Cedrik-Marcel Stebe.

Qualifying Rounds

Many players split their time between challengers and qualifiers, so it wouldn’t make sense to have one without the other.  Qualifying matches for tour-level events back to 2007 are now in the database, and most have stats.   A glance at David Goffin’s page now tells the more complete story of his path to the French Open round of 16.

Davis Cup

Since I launched the site, Davis Cup has been the most frequent request.  Now it’s here.  World Group back to 1981.  World Group play-offs back to 2003.  Groups I and II back to 1994.  You can now check out the Davis Cup career of Andy Roddick, among hundreds of others.

I hope you enjoy these additions to TennisAbstract.  As always, please let me know if you find bugs or errors, or if you have suggestions to improve the site.
