Novak Djokovic's spot as World No. 1 is not in immediate danger, with Serb recording a 412th week in that position.
Djokovic has not been in action since surrendering his Australian Open crown in the semifinal stage last month and remains with 9,855 points. He did not feature in Serbia's Davis Cup qualifying tie against Slovakia and has seemingly decided to skip all tournaments in February.
Although his rivals can slightly bridge the gap, it is impossible for him to relinquish the No. 1 spot this month. That means Carlos Alcaraz, who is in second place, must defend 550 points during the Golden Swing to avoid losing further ground.
Daniil Medvedev sits in third position, although he could be overtaken by Jannik Sinner by the end of the week should the Italian triumph at the Rotterdam Open. There are no entrants into the world's Top 10 this week.
Grigor Dimitrov lost the chance to unseat Stefanos Tsitsipas from the ATP's elite group after losing the Marseille final. The Bulgarian remains in the 13th spot, but the eventual champion, Ugo Humbert, motors three spots to a career-high ranking of World No. 18.
Dallas Open runner-up Marcos Giron soared 15 places to 52nd in the rankings, just three spots shy of his best-ever ATP ranking. The biggest mover in the world's Top 100 is Italy's Luciano Darderi.
The 21-year-old, who was actually born in Argentina, won the Cordoba Open in his first ATP final in an all-qualifier battle against Facundo Bagnis. He was assured a Top 100 debut regardless of Sunday's outcome but has now risen to the dizzying heights of World No. 76 - a leap of 60 spots.
Sumit Nagal became the 10th Indian man to break the world's Top 100 (up to 98th) after winning the Chennai Challenger in his home country without dropping a set. You can stay up to date with all the changes from this past week by visiting our dedicated rankings page.
