Despite his absence at this year's Asian swing, Novak Djokovic will remain as the ATP's No. 1 ahead of rival Carlos Alcaraz, who only partially reduced the arrears in the latest ATP rankings.
The Serbian lost 500 points this past week, which he earned from winning the Astana Open last year. His points total stands at 11,045. Alcaraz added 90 points to his tally, bringing the difference between them to 2,240 points.
The Spaniard will need a minor miracle to overhaul that deficit, especially with reports that he could potentially withdraw from Basel. There are also changes with the other Top 10 players. Russia's Andrey Rublev rises to fifth - his previous career-best ranking after a runner-up finish in Shanghai.
That means Holger Rune and Stefanos Tsitsipas each drop down a spot to sixth and seventh respectively. While American Taylor Fritz falls to 10th after his winner's points from last year's ATP 500 in Tokyo were wiped off (because of calendar changes, Fritz will be able to defend those points this week).
Hubert Hurkacz is the biggest mover in the world's Top 20, rising six places to 11th after winning his second Masters title in Shanghai. While Grigor Dimitrov who had a sizzling run at the tournament, made even more special by knocking out Carlos Alcaraz, soars to 16th spot.
Another player who had a brilliant week in Shanghai was Sebastian Korda, who stunned Daniil Medvedev for the second time this season en route to the semis. The American climbs to a career-high mark of No. 23. France's Ugo Humbert rejoins the Top 30 after a quarterfinal run at the penultimate Masters event.
Canada's Denis Shapovalov and Spain's Roberto Bautista Agut are on the verge of a Top 50 exit. Shapovalov hasn't played since Wimbledon, while Bautista Agut last featured on the ATP Tour in July (due to return at this week's Stockholm Open).
Hungary's Fabian Marozsan continues his ascent, adding 150 points, after earning a second Top 10 scalp of his career in Shanghai with a run to his first Masters 1000 quarterfinal. He'll make his Top 70 debut at No. 65. Tomas Machac's fine season on the Challenger Tour continued.
The powerful Czech captured the Mouilleron-Le-Captif Challenger title a week ago, vaulting to 81st in the rankings - his career-high, while France's Constant Lestienne re-enters the Top 100 after winning the Alicante Challenger in that same week.
