Iga Swiatek of Poland won the French Open on Saturday, becoming the third unseeded player in the previous four years to do so.
This is the fourth Grand Slam championship for Swiatek, who has dominated on Parisian clay.
Since rising to the top spot in April of last year, Swiatek has now lost just two of 26 Grand Slam matches. At the age of 22, she also became the youngest woman to win consecutive Roland Garros titles since Monica Seles, who did it from 1990 to 1992.
The winner of the US Open also joined Seles and Naomi Osaka as the only women in the Open Era to win each of their first four major finals, but despite a strong start, she had to put in a lot of effort.
“First of all, congratulations to Karolina,” Swiatek added. “I hoped there would be many more finals, but I knew it would be a tough match.
“I’m happy for your squad. I am well aware of the value of teams since I would not be present. I apologise to my employees for being such a hassle. I’ll work to improve.
“Thank you to my family as well; so many came from Poland and I feel the love,” he said. “I know we won this tournament but it’s not easy. Being on tour for two weeks, it’s tough.
It’s not just the show; I genuinely enjoy being here; this is my favourite location on the tour.
On a warm and windy afternoon on Court Philippe Chatrier, Swiatek handled the angles brilliantly from the baseline and raced ahead 3-0 before world number 43 Muchova calmed the nerves, scored, and made a comeback attempt.
Muchova, 26, had opportunities in the fifth game of the first set but unable to convert on them. She then got into more danger in the following game before saving herself with a tight hold due to a lovely drop shot and backhand winner.
The Czech, who won the only matchup between the two in Prague in 2019, threw herself at Swiatek’s second serve, but she committed far too many errors and let her opponent take a set and a break lead in 44 minutes.
The Czech blasted a rocket of a forehand to break back and then even the score at 3-3 in the second set, but Swiatek continued to profit from Muchova’s errors from the baseline and at the net.
