Carlos Alcaraz of Spain has been on a winning spree of late. While he earned his number one ranking in the ATP Singles for the first time in his career a few months back, on Tuesday, he assured his year-ending finish as the world number one. It all happened after Casper Rudd of Norway defeated Taylor Fritz of the United States of America (USA) in the group stage of the ATP Finals 2022 at Pala Alpitour in Turin on Tuesday. As a result of this number-one finish for Alcaraz, he has become the youngest lad to ensure a year-end numero uno finish at 19. Notably, he is the first teen to achieve this accomplishment.
