19-year-old Jannik Sinner makes his Cincinnati debut on Monday - a very different player to the one who appeared in the same tournament - the Western & Southern Open - when hosted last year in New York, due to COVID restrictions. "You know, the goal is the same - trying to improve as a player," said the Italian on Sunday. The 11th seed captured the biggest title of his career with victory in the Citi Open final little more than a week ago - his maiden ATP 500 crown. He faces the left-handed Federico Delbonis for the first time in the Round of 64.
