Italian tennis player Jannik Sinner has a golden opportunity to finish the year as the world number one, although it depends not only on him. Sinner, currently ranked second in the ATP, won the ATP 500 in Vienna, defeating German Alexander Zverev in a tight final. He has now reached the quarter-finals of the Paris Masters 1000, the last tournament of this category in the season. The surprising defeat of Spanish world number one Carlos Alcaraz in Paris has opened the door for the Italian to dream of finishing the season at the top of the rankings, but he must win everything in the coming weeks and hope for some favorable results. Should he win the Paris Masters 1000, Sinner would return to the world number one spot with 11,500 points, surpassing Alcaraz, who has 11,250. However, the situation becomes more even at the ATP Finals, the year-end tournament for the top eight players of the season. Since Sinner is the reigning champion, he would not add any ranking points by winning the title again, whereas Alcaraz is only defending 200 points. Therefore, Alcaraz would only need to score 600 points at the ATP Finals, which is possible if he wins all three of his group-stage matches to secure the year-end world number one ranking. There is also a scenario where Alcaraz and Sinner could face each other in a match that could be decisive for the world number one ranking.
