For the first time since the ATP Rankings was introduced in 1973, players from five different regions of the world have been represented in the top 10, including six from Europe, and one each from Africa, Asia, North America, and South America.
The ATP Rankings has witnessed the year-end top 10 from 10 different countries for the second time in three years.
