The Canadian ninth seed clinched a 7-6 (7/3), 6-4 victory at the La Defense Arena, as Bublik crumbled from 4-1 up in the second set of his maiden Masters 1000 semi-final.

“It’s a pleasure. All finals of Masters 1000s are a dream, but (especially) in Paris, a tournament with so much history and important past champions,” said Auger-Aliassime.

“I hope I can get the support of the French crowd for one more day to push me to the end.”

Auger-Aliassime climbs above Lorenzo Musetti into the eighth and last qualifying spot for the ATP Finals in Turin later this month.

The 25-year-old can seal his second appearance in the season-ending tournament with victory in Sunday’s showpiece match.

Auger-Aliassime fell just short of a Masters title at the 2024 Madrid Open against Andrey Rublev.

Bublik, who made the French Open quarter-finals in Paris earlier this year, can no longer reach the Finals despite an excellent year in which he has won four ATP titles.

A tight first set flew by without a single break-point opportunity, before two weak forehands into the net from Bublik allowed a rock-solid Auger-Aliassime to win the tie-break.

The match burst into life early in the second. Bublik seized a 2-0 lead only to give the break straight back.

He reacted by smashing his racquet, repeatedly, against the court, earning himself a code violation.

Auger-Aliassime swept up some of the racquet remnants with a towel ahead of the next game, to the gratitude of his opponent.

The Canadian presented Bublik with another gift, firing a simple volley well wide as he slipped 3-1 behind.

World number 16 Bublik could not maintain his momentum.

Auger-Aliassime reeled off five successive games against an increasingly forlorn Bublik, taking his first match point with a thumping cross-court forehand.
