Hard Court Singles Rankings, 3/21/11

About two weeks ago, I introduced my ranking system.  Much of the rationale is explained here.  The important thing to keep in mind is that the system is designed to be predictive–that is, it values the things that tend to correctly forecast the outcome of matches.

Since then, I’ve made a few tweaks under the hood.  For the most part, the changes don’t affect the rankings, they just adjust the differences between players to better reflect surface-specific skills.

Still, Roger Federer is hanging on at the top, though it’s so close that it should be considered virtually a tie.  My algorithm to predict the outcome of individual matches also takes head-to-head results into account, and given Novak Djokovic’s recent dominance, that algorithm now gives Djokovic the slight edge in a battle with Federer.

The real value, here, is a little further down the list, as this system is much better than the ATP rankings at measuring the skill level of players who are scoring big upsets and enjoying recent success.  To wit, Ivo Karlovic is up to #33 here, in part thanks to his giant-killing run last week.  Also, my system places Ryan Harrison at #71 and Donald Young at #82 for similar reasons.

I intended for this to be a top 100, but #101 is Somdev Devvarman, notable due to his string of upsets, which moved him all the way up from #147.
