Thanks to all who have suggested trivia topics — you’ve sent me some good ones. Keep them coming. Today I’ve got tidbits on three winners from Indian Wells: Belinda Bencic, Tallon Griekspoor, and Camila Osorio.

Better Belinda Bencic

Great dig from Oleg:

Those numbers include Bencic’s upset of Coco Gauff, but not her loss yesterday to Madison Keys. So the current top-five tally is 19-16, still comfortably better than her record against the next five, or the next ten after that.

The top five typically does not allow things like this. Since 1984, when my week-by-week ranking data begins, the WTA top five has won 79% of matches. That’s a healthy margin ahead of 69% for players ranked 6-10 and 64% for 11-20.

So, is Bencic alone? We’re looking for players with plenty of meetings against each of the three groups. She has 35 or more against each; let’s set the bar lower, at 20. I found 151 such players. Of those, we want to find those who have a better winning percentage against the top five than against the next five, and a better winning percentage against 6-10 than versus 11-20.

No dice. Belinda is the only one. 18 women managed a better record against the top five than the next five:

Player                    W% v1-5  W% v6-10  
Serena Williams             76.5%     62.7%  
Belinda Bencic              54.5%     48.6%  
Karolina Pliskova           46.0%     39.5%  
Jelena Ostapenko            44.8%     37.0%  
Maria Sakkari               41.2%     39.4%  
Kristina Mladenovic         40.9%     33.3%  
Daria Kasatkina             40.5%     24.2%  
Donna Vekic                 37.5%     20.0%  
Flavia Pennetta             37.2%     28.6%  
Marion Bartoli              30.2%     29.7%  
Samantha Stosur             29.0%     26.4%  
Elise Mertens               25.0%     19.0%  
Iva Majoli                  23.9%     22.6%  
Katarina Srebotnik          23.8%     20.0%  
Barbora Strycova            17.9%      9.7%  
Marianne Werdel Witmeyer    17.4%     13.0%  
Karina Habsudova            17.2%     11.1%  
Raffaella Reggi Concato     17.2%      5.9%

(All of these numbers, including Bencic’s, exclude Indian Wells.)

Comparing records against “next five” and “ten after that” is a bit odd in isolation, so instead, let’s compare top-ten and next-ten records. That’s an even more limited group:

Player               W% v1-10  W% v11-21  
Belinda Bencic          51.4%      35.0%  
Kiki Bertens            47.9%      38.2%  
Anett Kontaveit         40.4%      40.0%  
Kristina Mladenovic     37.0%      34.0%  
Donna Vekic             27.8%      26.8%  
Tsvetana Pironkova      25.0%      17.2%  
Katarina Srebotnik      21.7%      20.8%

Lots of these margins are close; Belinda’s is not. Maybe this explains the recent downward ranking moves of Elena Rybakina and Jasmine Paolini. They fear their colleague from Switzerland, so they’ve fled the top five so as to give her less motivation.

Tallon Griekspoor is no Bencic

Heading to the desert, Tallon Griekspoor held a 0-18 career record against the top five:

Some good fights in there, but a zero is a zero. That changed last Friday, when the Dutchman outlasted Alexander Zverev in a third-set tiebreak. Zverev has given several men a top-five victory in the last few weeks, but it still counts.

We have a few questions, then:

  1. Is Griekspoor’s top-five losing streak the longest ever to start a career?
  2. Is it the longest to be broken?
  3. How does it compare to top-five losing streaks, including those that don’t start a career?

Losing your first 18 matches against top-fivers gets you into the conversation, but Griekspoor stopped five defeats short of the record. These numbers all go back to 1982, the first year for which I have week-by-week ATP rankings. Here’s the all-time list:

Player             Losses  Broken?  
Fabio Fognini          23      Yes  
Jeff Tarango           23       No  
Jarkko Nieminen        23      Yes  
Simone Bolelli         22      Yes  
Diego Schwartzman      22      Yes  
Francisco Clavet       21      Yes  
Potito Starace         20       No  
Tomas Carbonell        20      Yes  
Victor Hanescu         19       No  
Tallon Griekspoor      18      Yes  
Leonardo Mayer         18       No  
Ryan Harrison          18       No  
Alex De Minaur         18      Yes 

It’s easy to dunk on Fabio Fognini, but in fairness, he came up at a very difficult time to score a top-five win. Check out the list of opponents for those 23 losses:

And yes, after all that, Fognini ended the string by beating Nadal. On clay. Twice.

I also need to mention Tomas Carbonell. He ended his 20-match losing streak with an upset of 5th-ranked Jonas Bjorkman … and that was it! He finished his career on at least one winning streak.

What about top-five losing streaks, not limited to those at the beginning of a career? Here are the longest runs of top-five futility, again going back to 1982:

Player                 Streak     
Andreas Seppi              32     
Viktor Troicki             28     
Philipp Kohlschreiber      27     
Jeff Tarango               23  *  
Fabio Fognini              23  *  
Jarkko Nieminen            23  *  
Jimmy Connors              23     
Eliot Teltscher            22     
Simone Bolelli             22  *  
Diego Schwartzman          22  *  
Andres Gomez               22     
Marin Cilic                22     
Gilles Muller              22     
Francisco Clavet           21  *

(Starred players are those from the previous list.)

Before we get to Seppi, Teltscher deserves an honorable mention here. His 22-loss streak started in early 1982, right after he upset John McEnroe at the season-ending Masters event. Had he lost that match, the string would have extended to 34, since the McEnroe upset broke a separate 11-loss streak.

Seppi’s long run of frustration would have been hard to predict: He had beaten Lleyton Hewitt and Nadal before he broke into the top 40 himself. But the 2008 victory over Rafa would be his last top-five win for nearly seven years:

As with Fognini, not an easy time to knock out anybody in the top five.

Finally, did you notice Jimmy Connors on the list? He is by far the greatest player to suffer such a long losing streak, and it was all the more notable because it began when he was a top-two player himself. He was responsible for 15 of Teltscher’s losses, but by 1985, things turned south for Jimbo:

Connors was 32 years old when the streak began, so it didn’t entirely come out of the blue. Still, that’s a tough run for a top-ten player.

Defeats of former number ones

Camila Osorio opened her Indian Wells campaign with a straight-set win over Naomi Osaka. It wasn’t exactly a shock, as Osorio is ranked slightly above Osaka. But here’s a different spin on it:

Is this something we’re doing now? I mean, great for Camila and Colombia–I’m always happy to see a tennis non-powerhouse getting attention. But “former number one” spans a fair few players, some of whom have stuck around long after they fell from the top of the list. Victoria Azarenka alone has lost over 100 matches since she first dropped out of the top ten in 2014.

Still, what the hell, let’s play.

Going back to 1984, there have been 27 WTA number ones. I’m going to count wins against the current number one as well–presumably those are at least as noteworthy as beating a former top player. Since the beginning of my week-by-week ranking data, current or former number ones have lost 2,587 matches.

Here are the stars who have handed out the largest number of noteworthy(?) victories. Unlike some loss leaderboards, this isn’t necessarily a bad thing. Azarenka is a good example: Inclusion here says more about longevity than anything else. So, losses after first reaching the number one ranking:

Player                   Losses  
Venus Williams              219  
Jelena Jankovic             205  
Caroline Wozniacki          192  
Arantxa Sanchez Vicario     168  
Ana Ivanovic                162  
Victoria Azarenka           142  
Karolina Pliskova           131  
Maria Sharapova             130  
Serena Williams             116  
Angelique Kerber            114

Osorio represented Osaka’s 49th such loss. Venus Williams has allowed 108 different women to put “beat a former number one” on their CV, and Osaka is already up to 33.

All told, 369 women have now beaten a current or former number one in the last four decades. They represent 52 different countries, now including Colombia.

It really isn’t that elite of a group. Osorio has better achievements to brag about, including–to bring us full circle–a top-five win, one that took her far fewer than 18 tries to accomplish.
