Iga Swiatek will have a chance to win her third career grand slam after defeating Aryna Sabalenka 3-6 6-1 6-4 in a gutsy come-from-behind win in Thursday's semi-final.
Poland's Swiatek, who has also won the French Open in 2020 and 2022, will play Ons Jabeur in the decider after the Tunisian won her semi-final against the in-form Caroline Garcia in straight sets earlier on.
It continues a remarkable season for the 21-year-old Swiatek, having also reached the semi-final at the Australian Open, before rattling off a 37-match winning streak that saw her claim six titles in a row and put a massive gap on the field as the world number one.
Belarus' Sabalenka was impressive in the opening set, attacking Swiatek's second serves to generate plenty of break points. She won 10-of-12 opportunities against Swiatek's second serve in the first frame, creating six break point chances and taking three.
Things flipped in the second set, and it was all about Swiatek making the adjustments, increasing her first serve accuracy from 64 per cent in the opener to 94 per cent in the second.
She won 14-of-17 points in those situations in the second frame, and converted all three of her break point opportunities as Sabalenka got sloppy, committing 15 unforced errors with only six winners.
Sabalenka threatened to run away with things late – twice managing to go up a break in the third set – but Swiatek showed composure beyond her years as she continued to fight back.
From 4-2 down in the decider, Swiatek rattled off the next four games in a row, going up 40-0 against Sabalenka's serve in the final game and finishing things off with her second match point.

She is also the first number one seed to reach the US Open final since Serena Williams did it back in 2014, snapping the equal-longest drought at any grand slam in the Open Era.
