The US Open semi-finalist leapfrogged Italy's Lorenzo Musetti into eighth place in the ATP world rankings and could secure his second appearance at the year-end tournament in Turin after 2022 if he wins Monday's (AEDT) final.

The 25-year-old, though, will need to be at his best to beat rampant four-times grand slam champion Jannik Sinner, who crushed world No.3 Alexander Zverev 6-0 6-1 in their semi-final.

Sinner's motivation to win the final will be the possibility of returning to No.1 in the world as a result of Carlos Alcaraz's shock early exit from Paris.

"I'm so happy. A Masters 1000 final sounds so good. You don't play those finals every week. Hopefully, I can go all the way and get the title," Auger-Aliassime said.

"But in terms of today, you get into a Masters and every match is tough. 

"You're always kind of curious to see how your game is going to match up.

"I have deep self-confidence in my game, I know what I can do against the best players in the world but you still have to go and execute. Today I did really well and I'm happy with the result."

The opening set was a serving clinic from both players, with neither conceding a break or even a break point. Locked at 6-6, the set went to a tiebreak, where Auger-Aliassime seized a 4-2 lead and closed it out comfortably.

In a scrappy second set, No.13 seed Bublik, who defeated Australia Alex de Minuar to get here, started brightly, breaking Auger-Aliassime early to take a 2-0 lead.

But the Canadian world No.10 responded immediately by breaking back, drawing frustration from Bublik, who smashed his racquet.

Bublik recovered to take a 4-1 lead, but Auger-Aliassime came to life, reeling off five straight games to seal his place in the final in one hour and 36 minutes.

Auger-Aliassime showcased his serving prowess in the first set, firing 10 aces compared to Bublik's four. The Canadian also delivered 31 winners overall, more than double the tally of his opponent.

Playing his 10th ATP Tour-level semi-final of the season, Auger-Aliassime extended his head-to-head record against Bublik to 4-2, having previously beaten the 28-year-old in the Round of 32 at the Dubai Tennis Championships in February.

Auger-Aliassime is chasing his fourth title of the season, having triumphed in Brussels, Montpellier and Adelaide.
