This is my update to my ranking of the best countries on the ATP right now. The rankings are all based on a simple formula. Each country is ranked by the sum of all the singles ranking points earned by each player from that country that is ranked within the top 140.
Spain has been on top of this list since I started calculating it in 2011. Now, with most Spaniards into their 30s, it's just a matter of time before some other country supplants them. France has always been the biggest threat to Spain, but now that Djokovic is dominating more than ever before and Troicki is back, Serbia also has a chance. In fact, through the top 78 in the world, Serbia is ahead of Spain.
The United States is also doing better than at any other time since I began compiling this list. USA comes in fourth place and also has 14 players in the top 140, which is second only to Spain. Through the top 123, the United States actually has the most representatives with 13, while Spain and France both have 12.
Here are the rankings as of Aug. 1:
4. United States
5. Great Britain
10. Czech Republic
23. South Africa
31. Chinese Taipei
34. Bosnia & Herzegovina
35. Dominican Republic
39. South Korea
