Swiatek overcame a second-set crisis and a third-set deficit to beat Muchova 6-2, 5-7, 6-4 and collect her third career championship at the French Open and fourth Grand Slam title.
The No. 1-ranked Swiatek raced to a 3-0 lead after just 10 minutes in Court Philippe Chatrier — taking 12 of the initial 15 points — and then was ahead 3-0 in the second set, too, before Muchova made things more intriguing.
