How Sinner can retake World No. 1 from Alcaraz in Paris

  • Posted: Oct 28, 2025

Jannik Sinner has an opportunity to reclaim World No. 1 from Carlos Alcaraz this week at the Rolex Paris Masters.

Alcaraz took the spot from his rival after winning the US Open and has held it since. The Italian can return the favour at the final ATP Masters 1000 event of the season… at least for now.

Sinner must win the title to have a chance of returning to World No. 1 next Monday. If the 24-year-old lifts the trophy and Alcaraz does not reach the semi-finals, No. 1 will change hands.

PIF ATP Live Rankings (entering Paris)

 Paris Result  Carlos Alcaraz  Jannik Sinner
 R32  11,250  10,510
 R16  11,340  10,600
 QF  11,440  10,700
 SF  11,640  10,900
 Finalist  11,890  11,150
 Champion  12,240  11,500

If Sinner does not claim his first Masters 1000 title of the season, he does not have a chance of returning to No. 1. Alcaraz can guarantee he will retain No. 1 by advancing to the semi-finals.

No matter what happens this week, Alcaraz remains in firm control of the battle for ATP Year-End No. 1 presented by PIF honours. The Spaniard currently leads the PIF ATP Live Race To Turin, a barometer for the year-end No. 1 battle, by 2,040 points.

Sinner, whose opening opponent in France will be Zizou Bergs, must move to within 1,750 points by the end of the Rolex Paris Masters to have any chance of claiming a second year-end No. 1 finish. There are ATP 250 events in Athens and Metz, which Alcaraz and Sinner have not entered, and then the Nitto ATP Finals, where an undefeated champion would earn 1,500 points.

Alcaraz begins his tournament on Tuesday when he takes on Cameron Norrie in the second round.
