After being two points away from securing the second set and match, Sabalenka was able to run away with the second set and come out in the third set with a 5-2 lead. Muchová did not give up, rallying to bring the match to 5 games a piece in the final set.
Muchová sealed the win with a beautiful kick serve outwide in the ad-box followed by a lethal backhand down the line, which Sabalenka returned but sprayed out.
Much of Muchová success came from incredible serving, executing six aces and winning 63% and 64% of first and second serve points, respectively.
In an impressive turn of events, Muchová broke Sabalenka's serve 5/5 times, a remarkable feat against such a strong server. Sabalenka won nearly 70% of her first serve points.
Muchová will face the winner of No. 1 seed Iga Swiatek and No. 14 Beatriz Haddad Maia in the French Open final on Saturday.
