In September, during the US Open, defending champion Stefanos Tsitsipas became the first player to qualify.[4] In October, he announced his withdrawal, having qualified for the 2019 ATP Finals.
On 16 September, Jannik Sinner was announced as the Italian wild card.[5] As of the October 28 deadline, Sinner reached the ranking of 8th player born in 1998 or later.
On 9 October, Félix Auger-Aliassime became the second player to qualify.[6]
On 16 October, Alex de Minaur qualified for the second consecutive year, having been the runner-up in 2018.[7]
Between 21 and 23 of October, Frances Tiafoe, Casper Ruud, Miomir Kecmanović and Ugo Humbert all qualified.[8] Mikael Ymer then qualified the following day after Félix Auger-Aliassime withdrew due to injury. Denis Shapovalov also withdrew on 1 November, which meant Alejandro Davidovich Fokina qualified.
The top seven players in the ATP Race to Milan qualified. The eighth spot was reserved for an Italian wild card, as in the past two editions. Eligible players had to be 21 or under at the start of the year (born in 1998 or later for 2019 edition).[9]
