Świątek's victory not only propels her closer to a second consecutive French Open title but also guarantees her retention of the top spot ranking after the tournament.
The 22-year-old Polish tennis sensation is now eyeing her third title at Roland Garros and fourth major championship overall.
Awaiting Świątek in the final is unseeded Karolina Muchova, a 26-year-old from the Czech Republic, who earlier on Thursday reached her first-ever Grand Slam final with a thrilling 7-6(5), 6-7(5), 7-5 victory over No.2 seed Aryna Sabalenka, the reigning Australian Open champion.
Despite a shaky start in the opening set, being broken at love in the first game, Świątek swiftly turned the tide in her favor.
In the second set, Haddad Maia gained a 3-1 lead, only for the Pole to fight back and level the score. The intense tiebreaker saw Haddad Maia squander a set point at 6-5 with a costly error, ultimately sealing her defeat.
With Sabalenka's defeat, Świątek,'s triumph also guarantees her continued reign at the top of the women's tennis rankings, solidifying her status as the World No.1 even beyond the conclusion of Roland Garros.
