Jannik Sinner returned to World No 1 by winning the Paris Masters on Sunday, but the Italian will hold top spot over Carlos Alcaraz for just one week before returning to World No 2 at the ATP Tour Finals in Turin.
Sinner defeated Felix Auger-Aliassime in the final to win the Paris title without dropping a set, with the Italian adding his 23rd career tournament and extending his indoor hard court winning streak to 26 matches.
