Many of you may have noticed that Kim Clijsters has fallen in the rankings, from No.3 to No.5, right after winning the US Open. On the other hand, the loser of the final Vera Zvonareva is now ranked higher, having risen from No.8 to No.4. Forty Deuce provided us with a wonderful insight into how this has happened and how it is actually perfectly fair and legitimate.
The rankings measure performance over the past 365 days, not just the current year and apparently not your whole career. Clijsters has had a better 2010 season than Zvonareva and it shows in the Race points, which sum up your points from the ongoing tennis season, that is from 2010 only. In the Race Clijsters is at No.3 ranked one spot higher than Zvonareva.
However, when we look at the last 365 days, Zvonareva has had better results. For example, Clijsters won the 2009 US Open and didn't play for the rest of the season, while Zvonareva earned some points in that period. (photos: © Neal Trousdale)
