The 26 year-old guaranteed his spot at the season finale in Turin by reaching the final eight in Paris, where he'll take on Alexander Bublik.

Before De Minaur qualified last year, the most recent Australian who played in the tournament was Lleyton Hewitt in 2004. Now De Minaur is returning to compete at Inalpi Arena for the second time.

The seventh Turin qualifier won the third ATP 500 of his career this year in Washington, where he saved three championship points in a dramatic final against Alejandro Davidovich Fokina.

De Minaur also made the final in Rotterdam and semi-finals in Monte-Carlo, Beijing and Vienna. He earned the 300th tour-level victory of his career in Vienna.

The Australian leads the ATP Tour in hard-court wins with 42 as of his third-round victory over Khachanov.

Only one spot remains at the year-end championships, with Carlos Alcaraz, Jannik Sinner, Alexander Zverev, Novak Djokovic, Ben Shelton and Taylor Fritz already qualified. Lorenzo Musetti is eighth in the ATP Live Race To Turin, with Felix Auger-Aliassime 290 points behind. The Canadian is into the Paris quarter-finals.
