Having been searching for her best form in recent months, Iga Swiatek, who struggled in the previous round, was in total control in the opening set.

Lorenzo Musetti reached his first semifinal at the French Open and second at a Grand Slam tournament. The 23-year-old Italian beat Frances Tiafoe of the United States 6-2, 4-6, 7-5, 6-2 in the same stadium where he won a bronze medal at last year’s Olympics.

Four-time champion Iga Swiatek has posted a 26th successive win at Roland-Garros and set up a French Open semifinal clash against top-ranked Aryna Sabalenka.
