Last dance

Growing up, Keats was on my Leaving Cert English. One of the poems I loved was Ode on a Grecian Urn. It’s a lovely poem and the last few words are “Beauty is truth, truth beauty,that is all you know on earth, and all you need to know.”
 
That’s what I mean. He epitomises physical beauty in the way he plays and for anything we see that is beautiful in life we always feel there is a certain truth in it. It is an exposing of truth and that’s why people love sport. 
 
In a world of greys where nothing is clear, sport is clear. Sport defines stuff. We get winners and losers, villains and heroes. We get beautiful and ugly. He is the closest definition to beautiful as you can imagine playing any sport. Ali in his prime would have been a beautiful way to watch boxing. Definitely.
 
Roger also reminds me of a super hero in comic books. Real super heroes like Superman; even when he is under extreme pressure he never looks fully extended. If there is an avalanche or he has to lift up a mountain, he never looks like he is straining. 
 
He lifts the mountain with one hand. He never sweats. That’s Federer: you never feel that he is fully, fully extended. You always feel there is something left in reserve.
 

That's Mario Rosenstock on Roger Federer ahead of last weekend's Australian Open showdown with Rafael Nadal.

I stayed up until 5:30am watching the match. I had not seen near peak Federer and Nadal play in ages, and I'd given up hope that it would ever happen again. It felt like a privilege, a one time entry pass to a time machine that would take me to see two greats clash in their prime. I had some caffeine, to which I'm very sensitive, and plopped down in front of my TV for the night.

Perhaps they are a step slower than before. No one would expect anything less given their ages and accumulated wear and tear. And yet, to my eye, they seemed as good as ever.

I agree with Rosenstock that Federer's chief appeal has always been the aesthetic elegance of his game. Every shot of his seems choreographed for slow motion in an art gallery, like a piece of Bill Viola video art. That he never seems rushed or over-exerted implies that when you master the physical action of something, it becomes easy, not just in practice but in form. 

I disagree that Federer has never been fully extended, though. While his physical movements have never seemed strained, it is Nadal above all who has pushed Federer past his redline. I'll never forget the time Federer cried, after losing the 2009 Australian Open to Nadal, another match I stayed up all night to watch. Nadal owns a 23-12 edge vs. Federer head to head, but more than that numeric edge it's the way he's beaten Roger, almost physically overpowering him, to the point where he's seemed to break Federer's will. Rarely do you see Federer concede sets or go on strategic tilt, except vs. Nadal.

It's such a stylistic contrast, Nadal with almost no strokes that seem as effortless as any shot in Federer's arsenal (watch the highlights from their match and note that Nadal grunts after each stroke while Federer never makes a sound except for the occasional squeak of his sneakers). Every shot Nadal hits seems to require his full exertion, none more so than his forehand, which he hits with more topspin than anyone has ever hit a forehand . His follow through is so severe, the racket whipping up over his head and then back down over his opposite shoulder like a priest trying to whip himself on the back, that even without seeing the RPM statistics it is easy to believe they are unmatched in history.

It is that forehand, aimed at Federer's backhand wing, that has been decisive in so many of their matches. The one handed backhand is beautiful, especially Federer's, but it's a stroke uniquely vulnerable to shots with extreme topspin. Because of the way the human body is engineered, it is difficult to handle high balls, but the alternative, to stand closer and try to take those shots earlier off the bounce, requires incredible timing, strength, and coordination.

That's what was so incredible about Federer's win last weekend. In the past, he'd often shank backhands trying to handle Nadal's forehand, but in this match, I've never seen him hit his backhand so cleanly and aggressively. He sometimes won exchanges in which Nadal hit forehands at his backhand repeatedly (see for example the exchange that starts at 5:37 in this video), something that seemed unimaginable in the past.

More importantly, Federer finally changed tactice. Watch the highlights and look at where Federer's feet are in each exchange. Right up against the baseline. Now go back and watch Federer play Nadal in the French Open in 2007, to take an earlier confrontation between the two, and stare at Federer's feet again. He's several feet behind the baseline. He was taking backhands on the rise off the court, and whether it was his new, larger racket, which he switched to in recent years, or just improved timing, he was hitting the backhand as clean and as hard as he's ever hit it.

Commentators have long remarked that they'd love to see him switch up his strategy to challenge Nadal, his nemesis. Attack more second serves, approach net more, anything but trade with Nadal from the baseline. He did some of that in the Aussie Open final, but quite he was the aggressor while staying at the baseline. It was a surprise. The faster courts in Melbourne helped, but to switch things up at age 35 required, most of all, a fluidity of mind. What is it they say about old dogs and new tricks?

The chief obstacle to seeing them meet like this again is probably their health, and so I hope they start taking more extended breaks between the majors to rest rather than work themselves to death in practice or in other tourneys on the circuit. They've done the grind in the past. What we want now are just the peaks.

The aesthetics of tennis

While the graphically inclined would no doubt find the layouts of other athletic playing courts and fields intriguing, there is something special about the tennis court: pleasingly symmetrical, relatively small in size, and, since they contain at most four contestants, never so crowded that the design can be smothered by action. One does not play atop a tennis court so much as inside it. The same basic design is utilized by women and men, young children and the elderly, ball-chasing buoyant players and hard faced, serious drillers.

"It's set up with particular parameters in mind—like there's a doubles alley; it's a very functional grid, and it's a grid that I connect with," Fletcher said.

"It's a geometry that has a story to it."

B. David Zarley on why artists love tennis.

The path traced by a tennis ball during a rally conjures triangles and arcs and other geometric patterns that really tickle that union of math and art.

And don't even get me started on Roger Federer. I suspect the reason he's so many people's favorite player is not because he's one of the greatest players of all time but instead for the sheer aesthetic perfection of all his strokes. There are dozens of YouTube videos of Federer hitting tennis balls in slow motion, and watching them triggers such strange pleasure sensations in the brain that they can't be called anything but pornographic.

[Since Federer is out of this Australian Open, the most beautiful stroke left in the men's draw is his countrymen Stanislav Wawrinka's one-handed backhand. Here are 70 backhand winners of his in HD. When he keeps his front shoulder closed and wings the ball down the line from the backhand side...lord have mercy.]

Miscellany

  1. High frequency trading, betting on tennis edition. Given that in tennis the gap in the number of points won between the winner and the loser is often quite low, the difference of knowing who one a particular game can often swing the result expectations from one side to the other, opening up quick and short-lived arbitrage windows.
  2. Lance Stephenson, basketball buffoon. “Back when he was in high school, Stephenson appeared in a documentary directed by Adam Yauch, of the Beastie Boys, which centered on a pickup game between eight young basketball phenoms at Rucker Park, in Harlem. Joshua Hersh wrote about Stephenson’s role in the film for The New Yorker: “Stephenson appears to be having a lot of fun, throwing down slam dunks, and even, at one point, dancing a little jig. In the fourth quarter, muscling his way to a rebound, he smacks Love”—Kevin Love, then a player for U.C.L.A.—“in the face with his forearm, busting open his lip.”” This was prescient given Stephenson's slap of Norris Cole in the Heat's series-clinching victory the other day. I like the term “basketball buffoon.”
  3. The ideological Turing Test. “The Ideological Turing Test is a concept invented by American economist Bryan Caplan to test whether a political or ideological partisan correctly understands the arguments of his or her intellectual adversaries: the partisan is invited to answer questions or write an essay posing as his opposite number. If neutral judges cannot tell the difference between the partisan’s answers and the answers of the opposite number, the candidate is judged to correctly understand the opposing side.”
  4. Is it time to abolish the 7-day week? It is somewhat arbitrary, but I think the author minimizes the value of coordination in the knowledge economy. The tech world has already hacked the 7-day work week quite a bit. Many developers are nocturnal and work on a different cycle than other job functions.
  5. Selfish Play Increases during High-Stakes NBA Games and Is Rewarded with More Lucrative Contracts. This isn't meant to be another veiled reference to Lance Stephenson, though I wouldn't blame you for thinking it was. There's no “I” in “team,” but there is in “raise.” One of the reasons basketball is one of the hardest sports to quantitatively assess player value in is that an individual's statistical performance doesn't always correlate to the team's performance. That's much less true in a sport like baseball which is much more of a series of discrete individual confrontations.
  6. Virgin Atlantic reaches deal with US FAA on launching flights into space from New Mexico; first flight expected by end of 2014. Let's hope the Virgin Atlantic website is better than the Virgin America website. I'm not sure I can deal with the first world privilege that will be tweets from gazillionaires complaining they couldn't log on to purchase a space flight.

Are top tennis players aging more gracefully?

It was once a truism in pro tennis that you were over the hill at age 30. Consider, though, Roger Federer (32) and Serena Williams (33), to take two recent pro tennis players still competing at the highest levels.

Analysis indicates they are not anomalies.

In this paper, I investigate aging patterns among top ATP singles players between 1991 and 2012 and consider how surface effects, career length, and age at peak performance have influenced aging trends. Following a decade and a half of little change, the average age of top singles players has increased at a pace of 0.34 years per season since the mid-2000s, reaching an all-time high of 27.9 years in 2012. Underlying this age shift was a coincident rise in the proportion of 30-and-overs (29% in 2012) and the virtual elimination of teenagers from the top 100 (0% in 2012). Because the typical age players begin competing professionally has varied little from 18 years in the past two decades, career length has increased in step with player age. Demographics among top players on each of today’s major surfaces indicate that parallel aging trends have occurred on clay, grass, and hard court from the late 2000s forward. As a result of the changing age demographic over the past decade, the age of tennis’s highest-ranked singles players is now comparable to the age of elite long-distance runners. This evolution likely reflects changes in tennis play that have made endurance and fitness increasingly essential for winning success.
