Carlos Alcaraz and Novak Djokovic were among those to be negatively impacted in the latest ATP rankings.
Alcaraz's struggles at indoor tournaments continued at the Paris Masters last week. All 21 ATP finals the Spaniard has reached throughout his impressive career were at outdoor events.
The four-time Grand Slam champion entered this year's iteration of the Paris Masters, having never gotten past the quarterfinal in his three previous appearances, and there was no improvement this time either.
Alcaraz was stunned by home favorite Ugo Humbert in the round of 16. The Frenchman played outstandingly in a 6-1, 3-6, 7-5 triumph and finished as the runner-up to Alexander Zverev.
Unfortunately for Alcaraz, he opened up an opportunity for Zverev to overtake him at No. 2 after his early exit in Paris. The German took full advantage and sits at No. 2 ahead of the 21-year-old in the latest rankings.
Zverev has a great chance to finish as the year-end No. 2 after the ATP Finals that start on November 10th, but the Paris Masters champion believes Alcaraz is still ahead of him because he won the French Open and Wimbledon this year.
Novak Djokovic fell one place to No. 5 after dropping the 1000 points he earned last year from winning the Paris Masters. The Serbian withdrew from the tournament before it began.
That means Daniil Medvedev moved up to No. 4 despite losing in his opening match of the Paris Masters to Alexei Popyrin. Djokovic will likely qualify for the ATP Finals this week, but it is unknown whether he plans to compete at the tournament.
The Serbian won last year's ATP Finals but is open about his main priorities being the Grand Slams and representing Serbia. Greg Rusedski is among those who believe he will skip the year-end tournament to get 100% fit for 2025.
Sinner also withdrew from the Paris Masters, citing illness. That led to Zverev's cutting of his lead at the top. However, the Italian remains over 4,000 points ahead of Zverev and already secured the year-end No. 1 ranking weeks ago.
The players inside the Top 10 have not changed, but the order is different. Casper Ruud rose one spot to No. 7, and Alex de Minaur's run to the quarterfinal of the Paris Masters was enough for him to jump two places to No. 8.
Andrey Rublev, who had an angry meltdown in his loss to Francisco Cerundolo in Paris, fell to No. 9. Grigor Dimitrov dropped to No. 10, but reaching the quarterfinal last week allowed him to hang onto a place in the Top 10 after dropping his points from being the runner-up in Paris last year.
Ruud, de Minaur, and Rublev all still have a chance of qualifying for the ATP Finals, meaning the final week of tournaments to decide the qualifiers at the Moselle Open and the Belgrade Open should be thrilling.
Other ATP rankings changes include Holger Rune moving up to No. 11, Ugo Humbert rising to No. 14 after reaching the final of the Paris Masters, and Ben Shelton falling two places to No. 21.
