Rafael Nadal and Roger Federer, world number 1 and 2 respectively, continue to lead an unchanged ATP ranking among the top ten, after the update.
After the Spanish and the Swiss, Andy Murray appears on the third step of the podium, who will surely not play again this season to recover from his physical problems.
Among the South Americans, the best classified is Juan Martín Del Potro, who repeats in 19th position, after entering the top 20 last week.
The Argentine, in great shape at the end of the season, won his first title of the year in Stockholm on Sunday by beating Bulgarian Grigor Dimitrov 6-4 6-2 in the final. AFP
