By beating Daniil Medvedev in the final in Beijing, the Italian Jannik Sinner took a nice 4th place in the world by climbing three places, but he is still far behind the Russian who is still 3rd. Holger Rune, Stefanos Tsitsipas and Andrey Rublev therefore all lost a place in the top 10.
On the French side, Adrian Mannarino gained eleven places by winning the ATP 250 in Astana and moved to 23rd, but he narrowly missed entering the top 20 by being eliminated in the 3rd round in Shanghai by Andrey Rublev. He is still French number 1 ahead of Ugo Humbert, who is 34th in the world. There are eleven French people in the top 100, and even the French who are not there (or not yet) shine since they won 24 Challenger tournaments this year, a record for a country over a season, after the victory of Constant Lestienne (107th) in Alicante this week.
What is the ATP ranking?
Novak Djokovic regained the place of world number 1 at the expense of Carlos Alcaraz. The ATP ranking:
The ranking is updated every week and the points are valid for one year, but instead of being added, they are compared. In other words, the player's performance in a competition in the current year is compared to that in the same competition last year. The points obtained are added to the total to obtain a new total for the week, for a new ranking which comes out every Monday.
