14th (2,275 points) – Ben Shelton
The American has given himself an outside chance of qualifying for the Nitto ATP Finals after he won his maiden ATP Tour title in Tokyo. The 21-year-old defeated Aslan Karatsev in the title match at the ATP 500 event to become the sixth first-time tour-level winner of the year, jumping four places in the Pepperstone ATP Live Race To Turin as a result.

Shelton is still 825 points behind eighth-placed Holger Rune, who holds the final qualification spot. The lefty will need deep runs in Vienna and Paris if he is to seal his spot in Turin.

Sixth (3,705 points) – Stefanos Tsitsipas
The 25-year-old has consolidated his sixth-placed position in the Pepperstone ATP Live Race To Turin after reaching his fifth semi-final of the season in Antwerp. The Greek, who will compete in Vienna this week, is 650 points ahead of ninth-placed Taylor Fritz, who is outside of the cut.

Tsitsipas has fond memories at the Nitto ATP Finals, having won the title on debut in 2019. He is seeking his fifth consecutive appearance at the event.

Novak Djokovic, Carlos Alcaraz, Daniil Medvedev and Jannik Sinner have all qualified for the Nitto ATP Finals.
