U.S. Open: Pegula stuns Swiatek, Sinner overcomes Medvedev in quarterfinals

American Jessica Pegula and Italian Jannik Sinner advance to U.S. Open semi-finals, guaranteeing new champions this year.

Jessica Pegula ousted top seed Iga Swiatek in the quarter-finals to continue the rich vein of American success at the U.S. Open on Wednesday (September 5, 2024) while men's world number one Jannik Sinner beat Daniil Medvedev to book his spot in the semi-finals.

Pegula took advantage of an error-strewn performance from Swiatek to book a spot in her maiden Grand Slam semifinal 6-2 6-4, while Sinner prevailed 6-2 1-6 6-1 6-4 to reach the last four at Flushing Meadows for the first time.

The losses for Swiatek and Medvedev ensured that the U.S. Open will crown two new champions this year.

Sinner will face Jack Draper for a spot in a second Grand Slam final after the British surprise package earlier stunned hobbled Australian Alex de Minaur 6-3 7-5 6-2 to become the first British man to reach the semis since 2012.

Pegula, who had lost six previous Grand Slam quarter-finals, will take on Karolina Muchova after the unseeded Czech beat Brazilian Beatriz Haddad Maia 6-1 6-4 in the day session at Arthur Ashe stadium despite battling a "bug".

"I'm really happy to be through to the semi-finals," said Pegula, who joined male compatriots Taylor Fritz and Frances Tiafoe at the business end of the tournament.

"I thought I played a really clean match. I feel like I didn't really do anything that bad, and was able to kind of jump on her really early and I think frustrate her."
