A short look at how the tennis ranking system works


Just before the French Open in May/June, Rafael Nadal was ranked No 4, based mainly on the strength of his breathtaking return to tennis after a seven-month injury lay-off. He was seeded 4 for the 2nd major of the year in Paris, ahead of World No 5 David Ferrer. As expected, he won the tournament with a dominant 6-3 6-2 6-3 victory over fellow Spaniard David Ferrer. It therefore came as a surprise when the following day, Rafael Nadal dropped to No 5 and was replaced by the man he defeated the previous day, David Ferrer in the World Number 4 position.

So what happened?

The current tennis ranking system calculates how many points a player earns over a rolling 12-month period. Rankings are updated weekly throughout the year, except when a grand slam is underway they are updated after the tournament. How does it work? I’ll  give a very short explanation using a few examples from the US Open 2013. First, let me start by giving a summary of how many points are awarded for the tournaments.

 
ATP (Men’s Tennis)

Tournament level
Winner

Note:
1.       Points are also earned for Davis Cup and Olympic wins. As a general rule, The Top 30 players (based on previous year's year-end ranking) must play a minimum of four ATP 500 level tournaments during the calendar year, including at least one event following the US Open.

2.       To qualify for the year-ending Barclays ATP Tour finals, the points earned in the preceding 12 months will be used.

Now let’s consider the US Open 2013 and the top 3 male players

Player
Pre-US Open 2013 Points
2012 US Open results
Scenario
Novak Djokovic
10980
Finalist
-  If he wins, he’ll add 800 points
-  If he finishes runner up, he’ll not add any point
-  If he doesn’t make the final, he’ll lose points
 
Rafael Nadal
8860
Absent
Any point he wins adds to his existing points because he didn’t win any point from last year.
Andy Murray
8700
Winner
-  If he wins, he’ll not add any point
-  If he doesn’t win, he’ll lose points
 


Let me explain.


When coming into this year’s US Open, every point won by a player in last year’s US Open automatically gets deducted from his total points because it doesn’t form part of the new rolling 12-month period. He will have to earn those points all over again.

Consider Murray. He had 8700 points pre-US Open 2013. Because he won the 2012 event, he immediately loses the 2000 points this year. And since he was knocked out in the quarter final stage, he wins only 360 points. His total points post-USOpen 2013 therefore will be (8700-2000+360) = 7060

Ditto Djokovic.  He had 10980 points pre-US Open 2013. Because he finished as runner-up 2012 event, he immediately loses 1200 points this year. Because he finished runner-up again this year, his total points post-US Open 2013 therefore will be (10980-1200+1200) = 10980.

For Nadal, there were no points to lose, so all the 2000 points he won in winning this year’s US Open event will count towards his total points. Hence his new points total post-US Open 2013 will be (8860+2000)= 10860, just behind Djokovic.
In fact, because he was out injured between July 2012 - January 2013, every point he wins until end of January 2014 will add to his ranking points. In tennis parlance, he’s said to “have no point to defend”. This is also why he’s likely to finish the year as World Number One (Novak Djokovic has to defend the 3,000 points he won in London, Shanghai and Dubai before the end of the year).

For the Women, there was no change in either ranking points or position in the Top 2 because they (Serena Williams and Victoria Azarenka) finished the same way they did last year. But the general rules are the same.
 

The tennis ranking system is designed to recognise the current form of players and to discourage top players from missing tournaments. A player is prevented from earning points from the same event two years in a row unless he/she performs better than the previous year. In my opinion, it’s the fairest system that the tennis bodies could have come up with, despite the pockets of criticism. At least it is very easy to calculate, unlike the FIFA and UEFA Ranking Systems that no one seems able to interpret with relative certainty.
