Which players have the most volatile games and what does it say about them?

Not volatile temper, silly, volatile game. Volatile in the sense that a volatile player will break serve often but will also lose his serve a lot.

I, for one, believe that we are much better off embracing gambling and educating ourselves than bemoaning the trend and pointing fingers. To that end, I’ve been reading gambling advice on Betfair.com’s blog and found an interesting piece about volatility.

Matthew Walton rated all of the ATP players as follows: if the player broke serve or lost his serve, his volatility ranking would increase. If he held serve or failed to break serve, his volatility ranking would go down.

As you can imagine, big servers who don’t move all that well had low volatility rankings. Andy Roddick has the huge serve but he doesn’t break his opponent’s serve that much. Sam Querrey is in there too and so is Benjamin Becker who depends on his serve far too much. That may be why he’s slipped down to number 87 in the rankings. Querrey might want to take note of that and spend a lot more time on the clay developing his sliding skills.

Clay court players, as you’d also expect, since it’s harder to hold serve on clay, are the most volatile and Filippo Volandri is the most volatile of all. He’s already pretty popular with the bettors if you look at the number of suspicious matches his names pops up in but this is one more reason he’s popular and here’s why.

Betfair is a betting exchange. Bettors offer bets to each other rather than making bets with a bookmaker. A betting exchange is also different than the usual betting operation in that you can make bets throughout a match, not just before a match starts.

As Walton points out, there are a lot more mid-match betting opportunities on a match with volatile players than non-volatile players because Roddick and Querrey are in trouble if they lose their serve so the outcome is more predictable. If Volandri loses his serve, no big deal, because he breaks serve a lot too.

Why should you care if you’re not a day trader in the tennis market? The volatility ranking tells us some interesting things. As Walton also points out, if you’re in the middle of the pack it probably means you hold your serve well and break your opponent’s serve, which is a good thing.

Roger Federer and Rafael Nadal are in this group but so, surprisingly, is Ivo Karlovic. You’d think that being 6ft 10in would automatically put him in the “doesn’t move so well” category but apparently it doesn’t and that explains why his ranking has shot up in the latter part of this year.

Two other people in that mid-group are Paul-Henri Mathieu and Marcos Baghdatis and that means one thing: they have the potential to be top players, they just aren’t fulfilling their potential.

I don’t have time to lay down hundreds of bets but I would love to be on Betfair because they stream tennis matches from around the world. I can’t use Betfair, though, because I live in the U.S. and offshore gambling is illegal. If you have a few coins in your piggy bank and you love tennis, it could be worthwhile to set up an account just so you can see tennis matches from Beijing and Bangkok on your computer screen.

Just don’t come complaining to me if you lose your pennies. In other words, if you have any addictive tendencies, stick to the telly.
